Hiddeninput and readonly attributes in mvc
Tags: webdev, programming, aspdotnet, aspnet
Published: 2023-07-07 20:44:50

In the context of MVC (Model-View-Controller) frameworks, the `hiddeninput` and `readonly` attributes are commonly used in HTML forms to control the behavior of input fields.

1. Hidden Input:
The `hiddeninput` attribute is used to create an input field that is hidden from the user but can still be submitted with the form data. This is useful when you need to include certain values in the form submission that should not be visible or editable by the user. In MVC frameworks, you typically use a specific helper method or syntax to generate hidden input fields. For example, in ASP.NET MVC, you can use the `Html.Hidden` helper method to create a hidden input field:

```html
@Html.Hidden("FieldName", "FieldValue")
```

This will generate an HTML input field with the name "FieldName" and the value "FieldValue". When the form is submitted, this hidden field will be sent along with the other form data.

2. Readonly Input:
The `readonly` attribute is used to make an input field non-editable by the user. It allows the value to be displayed in the input field, but the user cannot modify or interact with it. This attribute is typically used when you want to display some data to the user that should not be changed. In MVC frameworks, you can apply the `readonly` attribute to an input field by setting it in the HTML attributes of the input element. For example:

```html
<input type="text" name="FieldName" value="Value" readonly>
```

In the above example, the input field with the name "FieldName" will display the value "Value" but will be non-editable.

It's worth noting that the `readonly` attribute only prevents user interaction with the input field on the client-side. It does not provide any server-side validation or security. Therefore, you should always validate and handle the data on the server-side to ensure its integrity and security.
Opening a page in new browser window in asp net mvc application
Tags: webdev, programming, aspdotnet, aspnet
Published: 2023-07-07 20:44:19

To open a page in a new browser window in an ASP.NET MVC application, you can use the `target` attribute of the anchor (`<a>`) tag. Here's an example:

```html
<a href="@Url.Action("ActionName", "ControllerName")" target="_blank">Open Page</a>
```

In this example, `ActionName` and `ControllerName` should be replaced with the appropriate values for the action method and controller you want to open in the new window.

The `target="_blank"` attribute tells the browser to open the link in a new window or tab, depending on the user's browser settings.

Alternatively, if you want to open a new window or tab using JavaScript, you can use the `window.open()` method. Here's an example:

```html
<a href="#" onclick="window.open('@Url.Action("ActionName", "ControllerName")'); return false;">Open Page</a>
```

In this example, when the link is clicked, the `window.open()` method is called with the URL generated using `@Url.Action()`. The `return false;` statement prevents the default action of the link, which is to navigate to the URL specified in the `href` attribute. Instead, the `window.open()` method is invoked, opening the URL in a new window or tab.

Remember to replace `ActionName` and `ControllerName` with the appropriate values for your application.

Using datatype and displaycolumn attributes in asp net mvc application
Tags: webdev, programming, aspnet, aspdotnet
Published: 2023-07-07 20:17:30

In an ASP.NET MVC application, you can use the `DataType` and `DisplayColumn` attributes to provide additional metadata for model properties, which can be used for validation and display purposes.

The `DataType` attribute allows you to specify the data type of a property. This can be useful for validating user input or formatting data when displaying it. Here's an example:

```csharp
public class Person
{
    [DataType(DataType.Date)]
    public DateTime BirthDate { get; set; }

    [DataType(DataType.EmailAddress)]
    public string Email { get; set; }
}
```

In this example, the `BirthDate` property is annotated with the `DataType` attribute and set to `DataType.Date`, indicating that the property represents a date value. Similarly, the `Email` property is annotated with the `DataType` attribute and set to `DataType.EmailAddress`, indicating that the property represents an email address.

The `DisplayColumn` attribute allows you to specify a column to use for display purposes when scaffolding views. It can be applied to a class to specify a default display column or to individual properties to override the default. Here's an example:

```csharp
[DisplayColumn("FullName")]
public class Person
{
    public string FirstName { get; set; }
    
    public string LastName { get; set; }

    [Display(Name = "Full Name")]
    public string FullName => $"{FirstName} {LastName}";
}
```

In this example, the `DisplayColumn` attribute is applied to the `Person` class, specifying that the `FullName` property should be used as the default display column. The `FullName` property is also annotated with the `Display` attribute, which sets the display name to "Full Name". This way, when scaffolding views, the `FullName` property will be used as the default display column, and its display name will be "Full Name".

These attributes can be helpful when working with form validation, generating views using scaffolding, or displaying data in a user-friendly format.
Using displayname, displayformat, scaffoldcolumn attributes in asp net mvc application
Tags: webdev, programming, productivity, api
Published: 2023-07-07 20:03:06

In an ASP.NET MVC application, you can use various attributes like `DisplayName`, `DisplayFormat`, and `ScaffoldColumn` to customize the way properties are displayed in views. These attributes provide metadata to the view engine and allow you to control the rendering of data.

1. `DisplayName` Attribute:
The `DisplayName` attribute allows you to specify a friendly name or label for a property that will be displayed in views. It is mainly used to provide a more user-friendly name for properties instead of using the property name itself. Here's an example:

```csharp
public class MyModel
{
    [DisplayName("First Name")]
    public string FirstName { get; set; }

    [DisplayName("Last Name")]
    public string LastName { get; set; }
}
```

In this example, the `DisplayName` attribute is used to specify custom names for the `FirstName` and `LastName` properties.

2. `DisplayFormat` Attribute:
The `DisplayFormat` attribute allows you to control the formatting of a property's value in views. It is useful when you want to display dates, numbers, or other data types in a specific format. Here's an example:

```csharp
public class MyModel
{
    [DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}")]
    public DateTime BirthDate { get; set; }
}
```

In this example, the `DisplayFormat` attribute is used to specify that the `BirthDate` property should be displayed in the format "yyyy-MM-dd".

3. `ScaffoldColumn` Attribute:
The `ScaffoldColumn` attribute controls whether a property should be automatically rendered in views. By default, properties are scaffolded (rendered) in views, but you can use this attribute to exclude certain properties. Here's an example:

```csharp
public class MyModel
{
    public string Property1 { get; set; }

    [ScaffoldColumn(false)]
    public string Property2 { get; set; }
}
```

In this example, the `Property1` will be automatically scaffolded in views, but the `Property2` will be excluded from scaffolding.

These attributes can be used in conjunction with other ASP.NET MVC features like HTML helpers and data annotations to provide a rich and customizable user interface in your application's views.
ListBox in asp net mvc
Tags: webdev, programming, aspdotnet, api
Published: 2023-07-07 20:02:24

In ASP.NET MVC, there is no specific "ListBox" control like in traditional ASP.NET Web Forms. However, you can achieve similar functionality using HTML and Razor syntax within your views.

To create a ListBox-like control in ASP.NET MVC, you can use the `<select>` HTML element with the `multiple` attribute set to allow multiple selections. Here's an example of how you can create a ListBox in an ASP.NET MVC view:

```csharp
@{
    // Define a list of items
    var items = new List<SelectListItem>
    {
        new SelectListItem { Value = "1", Text = "Item 1" },
        new SelectListItem { Value = "2", Text = "Item 2" },
        new SelectListItem { Value = "3", Text = "Item 3" }
    };

    // Retrieve selected values
    var selectedValues = new[] { "2", "3" }; // Example selected values
}

@Html.ListBox("selectedItems", items, new { @multiple = "multiple", @class = "form-control" })
```

In this example, we define a list of `SelectListItem` objects representing the items in the ListBox. We also define an array of selected values for pre-selecting some items.

The `Html.ListBox` helper method is used to render the `<select>` element. The first parameter is the name of the ListBox control (`selectedItems` in this case). The second parameter is the list of `SelectListItem` objects, and the third parameter is an anonymous object used to specify additional attributes for the `<select>` element.

The `@multiple = "multiple"` attribute allows multiple selections in the ListBox. The `@class = "form-control"` attribute is optional and can be used to apply CSS classes for styling purposes.

When the form is submitted, the selected values from the ListBox will be bound to a corresponding property in your model or controller action method. For example, you can have a property named `SelectedItems` in your model or method parameter to capture the selected values.

Note: This is just a basic example, and you can customize it further based on your specific requirements.
Generating a radiobuttonlist control in mvc using HTML helpers
Tags: webdev, programming, aspdotnet, devops
Published: 2023-07-07 20:01:35

In MVC, you can generate a RadioButtonList control using HTML helpers. However, please note that MVC does not have a built-in RadioButtonList control like Web Forms. You can achieve the same functionality by using a combination of HTML helpers and loops. Here's an example:

Let's assume you have a model called `RadioButtonListModel` with properties for the list items and the selected value:

```csharp
public class RadioButtonListModel
{
    public List<SelectListItem> Items { get; set; }
    public string SelectedValue { get; set; }
}
```

In your controller action, you can populate the `Items` property with the options for your radio button list and pass the model to the view:

```csharp
public ActionResult Index()
{
    var model = new RadioButtonListModel
    {
        Items = new List<SelectListItem>
        {
            new SelectListItem { Value = "option1", Text = "Option 1" },
            new SelectListItem { Value = "option2", Text = "Option 2" },
            new SelectListItem { Value = "option3", Text = "Option 3" }
        }
    };

    return View(model);
}
```

In your view, you can generate the radio button list using a `for` loop and the `Html.RadioButton` helper method:

```html
@model RadioButtonListModel

@for (int i = 0; i < Model.Items.Count; i++)
{
    <div>
        @Html.RadioButtonFor(m => m.SelectedValue, Model.Items[i].Value)
        @Html.LabelFor(m => m.SelectedValue, Model.Items[i].Text)
    </div>
}
```

In the code above, we're iterating over the `Items` list and generating a radio button and label for each item. The `RadioButtonFor` helper generates the radio button, and the `LabelFor` helper generates the label associated with the radio button. The `RadioButtonFor` helper uses the `SelectedValue` property of the model to determine the selected radio button.

Make sure to include the necessary namespaces in your view or add them in the `Web.config` file:

```html
@using System.Web.Mvc
@using System.Web.Mvc.Html
```

This way, when you navigate to the corresponding action in your MVC application, you should see a radio button list with the options you specified in the controller.
#DEVDiscuss: Is Threads Truly Decentralized?
Tags: devdiscuss, discuss, activitypub, socialmedia
Published: 2023-07-07 20:00:00

Hey Devs, happy Friday 🦥💚

As always, it's been an eventful week in the tech industry. We've got a lot to talk about! And today I want to discuss...Meta's new Instagram app Threads, and whether or not it's really decentralized.

In case you missed it, Meta (fka Facebook) has launched its Twitter competitor: an app for Instagram called [Threads](https://www.zdnet.com/article/5-things-to-know-about-metas-threads-app-before-you-entangle-your-instagram-account/). Part of the promise of Threads is that it will allow users more control over their privacy and platform allegiance than Facebook and Instagram because it will eventually use a decentralized protocol.

{% embed https://www.wired.com/story/meta-threads-privacy-decentralization/ %}

> Meta is dangling an opportunity to essentially be on Threads without signing up for the platform at all. The company announced yesterday that it is planning to make Threads interoperable with other, non-Meta social networks that support a decentralized protocol already used by WordPress and 2022’s decentralization poster child, Mastodon. 

> This means that if Meta follows through, you’ll be able to see and interact with Threads content from other platforms and services that support the standard, which is known as ActivityPub.

Based on Meta's [checkered history with data mining](https://www.nytimes.com/2018/04/11/technology/facebook-privacy-hearings.html) and privacy concerns, though, lots of privacy-minded social media users are feeling skeptical.

So, what do you think? Can a product by Meta ever truly be decentralized? And will you use it regardless? Share your thoughts in the comments and let's discuss!

Short note: Asana > Jira
Tags: jira, asana
Published: 2023-07-07 19:45:57

It is way quicker to use Asana's UI than Jira's UI, especially when dealing with dozens or hundreds of tasks/subtasks. It is simpler to navigate through and all team members are clear on what is being worked on. Jira is a constant dumpster fire of people getting lost in different views, no one ever wanting to use it, and out of date data as a result.

Please, if you are launching a new startup, consider Asana before going straight for Jira.
Enhancing Software Development: The Power of Effective Error Handling
Published: 2023-07-07 19:43:42

We recently [posted on our blog this article](https://codaea.blogspot.com/2023/05/improving-software-development-by.html), where we urge developers to take a stand with us.  You've probably heard it from managers who say "don't bring me a problem unless you also have some suggestions for a solution."  We are saying, don't present the user (or write to a log) with an error message - unless you also present a list of known solutions.  This is the beginning of Integrated Centralized Error Management (ICEM).  With ICEM, you can finally put the power of fixing problems into the hands of the people - the end users, administrators, and support staff who have to deal with the software every day.  And, leverage known solutions every time someone gets that error.

In fact, there is nothing that says you only have to use it for errors - it is perfectly appropriate for any message, to add explanation, translation, or nuance to the message so people can better understand what to do.  The world is complex enough - let's make our software simpler!

Please respond with your thoughts.
CheckBoxList in asp net mvc
Tags: webdev, programming, aspnet, api
Published: 2023-07-07 19:21:25

In ASP.NET MVC, you can use the `CheckBoxList` to create a list of checkboxes that allows users to select multiple items. However, please note that there is no built-in `CheckBoxList` control in ASP.NET MVC like in ASP.NET Web Forms. You'll need to create your own implementation or use a third-party library to achieve this functionality.

Here's an example of how you can create a `CheckBoxList` in ASP.NET MVC using a custom implementation:

1. Create a ViewModel to represent the data for the checkboxes. For example:

```csharp
public class CheckBoxViewModel
{
    public int Id { get; set; }
    public string Text { get; set; }
    public bool IsChecked { get; set; }
}
```

2. In your controller, populate a list of `CheckBoxViewModel` objects and pass it to the view. For example:

```csharp
public ActionResult Index()
{
    List<CheckBoxViewModel> checkBoxes = new List<CheckBoxViewModel>
    {
        new CheckBoxViewModel { Id = 1, Text = "Checkbox 1", IsChecked = false },
        new CheckBoxViewModel { Id = 2, Text = "Checkbox 2", IsChecked = true },
        // Add more checkboxes as needed
    };

    return View(checkBoxes);
}
```

3. Create a view (`.cshtml`) to render the `CheckBoxList`. For example:

```html
@model List<CheckBoxViewModel>

@using (Html.BeginForm())
{
    for (int i = 0; i < Model.Count; i++)
    {
        @Html.HiddenFor(m => m[i].Id)
        <div>
            @Html.CheckBoxFor(m => m[i].IsChecked)
            @Html.LabelFor(m => m[i].IsChecked, Model[i].Text)
        </div>
    }

    <input type="submit" value="Submit" />
}
```

4. Handle the form submission in your controller action. For example:

```csharp
[HttpPost]
public ActionResult Index(List<CheckBoxViewModel> model)
{
    // Process the submitted checkboxes here

    return RedirectToAction("Index");
}
```

This is a basic example to get you started with a custom implementation of `CheckBoxList` in ASP.NET MVC. Keep in mind that you might need to enhance this implementation based on your specific requirements. Alternatively, you can explore third-party libraries or extensions that provide a pre-built `CheckBoxList` control for ASP.NET MVC.
Difference between Html TextBox and Html TextBoxFor
Tags: webdev, programming, aspdotnet, devops
Published: 2023-07-07 19:20:41

In the context of ASP.NET MVC, both `Html.TextBox` and `Html.TextBoxFor` are methods that generate HTML input elements for text entry. However, they differ in the way they bind to model properties and provide strongly-typed support.

1. `Html.TextBox`:
   - This method is typically used when you want to manually specify the name and value of the input element.
   - It does not provide compile-time checking or strongly-typed support for model properties.
   - Example usage: `@Html.TextBox("Name", Model.Name)`

2. `Html.TextBoxFor`:
   - This method is used when you want to bind the input element directly to a model property.
   - It provides compile-time checking and strongly-typed support, which helps catch errors at compile-time rather than runtime.
   - Example usage: `@Html.TextBoxFor(model => model.Name)`

The `Html.TextBoxFor` method has the advantage of being strongly typed, which means it can automatically infer the type of the model property and generate appropriate input elements (e.g., `<input type="text">`, `<input type="number">`, etc.). It also generates the correct name attribute for model binding, allowing the MVC framework to automatically populate the corresponding model property during form submission.

Using `Html.TextBoxFor` is generally recommended because it provides better type safety and helps catch errors early in the development process. Additionally, it simplifies model binding and reduces the amount of manual code you need to write.

Adding Dark Mode in a single line of HTML

![Dark Mode](https://kumaram.dev/images/dark-mode.png)

This weekend, I wanted to explore how I can add dark mode to my website, for the benefit of the ~2 people who read my blog. I decided to keep it simple, and use the system-wide preference for the colour mode. I thought I might have to use arcane CSS and Javascript incantations to first query the system dark mode preference, and then set the colours accordingly, but the browser vendors have made it so much simpler and easy to use.

## Enough Talk! Show me the code

Here's all the code required to add dark mode to any website (with a few caveats I'll explain later in this post):

```
<meta name="color-scheme" content="dark light">
```

That's it! It requires no custom CSS, and is [supported in all modern browsers](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/meta/name#browser_compatibility). There's also a corresponding CSS property: `color-scheme`, which works on individual tags.

There's a major caveat though. If you've set custom colours anywhere in your page, using the `color` or `background` CSS properties, this won't work for you. It'll invert the colours only for elements which have no explicit colour set.

## Other approaches

If you make substantial use of custom colours in your web pages, you can use the[`prefers-color-scheme`](https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-color-scheme)media query in your CSS to get a more fine-grained control on how your webpage looks in different modes.

Here's an example:

```
@media (prefers-color-scheme: dark) {
  body {
    background-color: black;
    color: white;
  }
}
```

I hope this helps!
