How to set the Visibility of the Label in C#?

30 Jun, 2019
In Windows Forms, Label control is used to display text on the form and it does not take part in user input or in mouse or keyboard events. You are allowed to set the visibility of the Label control using the Visible Property in the windows form. The label is visible when the value of this property is set to be true.If the value of this property is set to be false, then the Label does not visible in the form. The default value of this property is true. You can set this property using two different methods:
1. Design-Time: It is the easiest method to set the Visible property of the Label control 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 Label control from the ToolBox and drop it on the windows form. You are allowed to place a Label control anywhere on the windows form according to your need.
Step 3: After drag and drop you will go to the properties of the Label control to set the Visible property of the Label.Output:
Output:
2. Run-Time: It is a little bit trickier than the above method. In this method, you can set the visibility of the Label control in the windows forms programmatically with the help of given syntax:
public bool Visible { get; set; }
Here, the value of this property is of System.Boolean type. Following steps are used to set the Visible property of the Label:
Step 1: Create a label using the Label() constructor is provided by the Label class.// Creating label using Label class
Label mylab = new Label();

// Creating label using Label class
Label mylab = new Label();

Step 2: After creating Label, set the Visible property of the Label provided by the Label class.// Set Visible property of the label
mylab.Visible = true;

// Set Visible property of the label
mylab.Visible = true;

Step 3: And last add this Label control to form using Add() method.// Add this label to the form
this.Controls.Add(mylab);
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 WindowsFormsApp16 {  public partial class Form1 : Form {      public Form1()    {        InitializeComponent();    }      private void Form1_Load(object sender, EventArgs e)    {        // Creating and setting the label        Label mylab = new Label();        mylab.Text = "GeeksforGeeks";        mylab.Location = new Point(222, 90);        mylab.AutoSize = true;        mylab.Font = new Font("Calibri", 18);        mylab.ForeColor = Color.Green;        mylab.Visible = true;          // Adding this control to the form        this.Controls.Add(mylab);          // Creating and setting the label        Label mylab1 = new Label();        mylab1.Text = "Welcome To GeeksforGeeks";        mylab1.Location = new Point(155, 170);        mylab1.AutoSize = true;        mylab1.Font = new Font("Calibri", 18);        mylab1.Visible = false;          // Adding this control to the form        this.Controls.Add(mylab1);    }}}Output:When the value of Visible Property is set to be true:When the value of Visible Property is set to be false:
// Add this label to the form
this.Controls.Add(mylab);

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 WindowsFormsApp16 {  public partial class Form1 : Form {      public Form1()    {        InitializeComponent();    }      private void Form1_Load(object sender, EventArgs e)    {        // Creating and setting the label        Label mylab = new Label();        mylab.Text = "GeeksforGeeks";        mylab.Location = new Point(222, 90);        mylab.AutoSize = true;        mylab.Font = new Font("Calibri", 18);        mylab.ForeColor = Color.Green;        mylab.Visible = true;          // Adding this control to the form        this.Controls.Add(mylab);          // Creating and setting the label        Label mylab1 = new Label();        mylab1.Text = "Welcome To GeeksforGeeks";        mylab1.Location = new Point(155, 170);        mylab1.AutoSize = true;        mylab1.Font = new Font("Calibri", 18);        mylab1.Visible = false;          // Adding this control to the form        this.Controls.Add(mylab1);    }}}
Output:
When the value of Visible Property is set to be true:
When the value of Visible Property is set to be false:
