RadioButton Control in VB.NET

The RadioButton component lets you force a user to make a single selection from a set of choices. This component must be used in a group of at least two RadioButton instances. Only one member of the group can be selected at any given time. Now, we will create a RadioButtons that when chose it will change the background color of the Form. So, now let's start this tutorial! 1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application. 2. Next, add three RadioButton named RadioButton1 labeled "Yellow", RadioButton2 labeled "Blue", and RadioButton3 labeled "Red". Then add a Button named Button1. You must design your layout like this: design 3. Now, put this code in Button1_Click. This will display the result of changing the color of our form when choosing the preferred color in Radio Buttons.
  1. Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
  2. If RadioButton1.Checked = True Then
  3. Me.BackColor = Color.Yellow
  4. Exit Sub
  5. ElseIf RadioButton2.Checked = True Then
  6. Me.BackColor = Color.Blue
  7. Exit Sub
  8. Else
  9. Me.BackColor = Color.Red
  10. End If
  11. End Sub

Explaination:

We use the code statement of If-else Decision statement to choose from the three different choices. RadioButton1 labeled "Yellow", RadioButton2 labeled "Blue", and RadioButton3 labeled "Red". The checked = True here is our event for our RadioButton as it toggles on and off. When we check RadioButton1, it will have a background color of Yellow ( Me.BackColor = Color.Yellow. The "Me" here indicates that we are referring to Form1. Next, When we check RadioButton2, it will have a background color of Blue ( Me.BackColor = Color.Blue. Otherwise, it will have a background color of Red.
