A Button is an essential part of an application, or software, or webpage. It allows the user to interact with the application or software. In Button, you are allowed to set a value which represents the button and its child buttons are displayed by using the Visible Property. It is provided by Button class.If you want to display the given button and its child controls, then set the value of Visible property to true, otherwise set false. The default value of this property is true. You can use this property in two different methods:
1. Design-Time: It is the easiest method to set the visibility of the button. Using the following steps:
Step 1: Create a windows form as shown in the below image:Visual Studio -> File -> New -> Project -> WindowsFormApp
Step 2: Drag the Button control from the ToolBox and Drop it on the windows form. You are allowed to place a Button control anywhere on the windows form according to your need.
Step 3: After drag and drop you will go to the properties of the Button control to set the Visible property of the Button.Output:
Output:
2. Run-Time: It is a little bit trickier than the above method. In this method, you can set the Visible property of the Button programmatically with the help of given syntax:
public bool Visible { get; set; }
Here, the return type of this property is System.Boolean. Following steps are used to set the Visible property of the Button:
Step 1: Create a button using the Button() constructor is provided by the Button class.// Creating Button using Button class
Button MyButton = new Button();

// Creating Button using Button class
Button MyButton = new Button();

Step 2: After creating Button, set the Visible property of the Button provided by the Button class.// Set the visibility of the button
MyButton.Visible = true;

// Set the visibility of the button
MyButton.Visible = true;

Step 3: And last add this button control to from using Add() method.// Add this Button to form
this.Controls.Add(Mybutton);
Example:using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;  namespace WindowsFormsApp8 {  public partial class Form1 : Form {      public Form1()    {        InitializeComponent();    }      private void Form1_Load(object sender, EventArgs e)    {          // Creating and setting the properties of label        Label l = new Label();        l.AutoSize = true;        l.Text = "Do you want to submit this form?";        l.Location = new Point(222, 145);          // Adding this label to form        this.Controls.Add(l);          // Creating and setting the properties of Button        Button Mybutton = new Button();        Mybutton.Location = new Point(225, 198);        Mybutton.Text = "Submit";        Mybutton.AutoSize = true;        Mybutton.BackColor = Color.LightBlue;        Mybutton.Visible = true;          // Adding this button to form        this.Controls.Add(Mybutton);          // Creating and setting the properties of Button        // This button in not visible in the output because the        // visibility of this button is set to be false        Button Mybutton1 = new Button();        Mybutton1.Location = new Point(438, 198);        Mybutton1.Text = "Cancel";        Mybutton1.AutoSize = true;        Mybutton1.BackColor = Color.LightPink;        Mybutton1.Visible = false;          // Adding this button to form        this.Controls.Add(Mybutton1);    }}}Output:Before setting the visibility of cancel button to false the output is like this:After setting the visibility of cancel button to false the output is like this:
// Add this Button to form
this.Controls.Add(Mybutton);

Example:
using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;  namespace WindowsFormsApp8 {  public partial class Form1 : Form {      public Form1()    {        InitializeComponent();    }      private void Form1_Load(object sender, EventArgs e)    {          // Creating and setting the properties of label        Label l = new Label();        l.AutoSize = true;        l.Text = "Do you want to submit this form?";        l.Location = new Point(222, 145);          // Adding this label to form        this.Controls.Add(l);          // Creating and setting the properties of Button        Button Mybutton = new Button();        Mybutton.Location = new Point(225, 198);        Mybutton.Text = "Submit";        Mybutton.AutoSize = true;        Mybutton.BackColor = Color.LightBlue;        Mybutton.Visible = true;          // Adding this button to form        this.Controls.Add(Mybutton);          // Creating and setting the properties of Button        // This button in not visible in the output because the        // visibility of this button is set to be false        Button Mybutton1 = new Button();        Mybutton1.Location = new Point(438, 198);        Mybutton1.Text = "Cancel";        Mybutton1.AutoSize = true;        Mybutton1.BackColor = Color.LightPink;        Mybutton1.Visible = false;          // Adding this button to form        this.Controls.Add(Mybutton1);    }}}
