How to set the Visibility of the Label in C#?
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:
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();
- 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;
- Step 3: And last add this Label control to form using Add() method.
// Add this label to the form this.Controls.Add(mylab);

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 =
"w3wiki"
;
mylab.Location =
new
Point(222, 90);
mylab.AutoSize =

;
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 w3wiki"
;
mylab1.Location =
new
Point(155, 170);
mylab1.AutoSize =

mylab1.Visible =
false
;

When the value of Visible Property is set to be true:
When the value of Visible Property is set to be false:
