Getting a Radio Button's State

You can check if a radio button is selected or not with the Checked property (formerly the Value property in VB6 and earlier). Radio buttons' Checked property only has two settings: True if the button is selected, and False if not.

Here's an example showing how to determine whether a radio button is selected or not. In this case, we display a message in a message box that indicates if a radio button, RadioButton1, is selected or not:

Private Sub Button1_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button1.Click
    If RadioButton1.Checked Then
        MsgBox ("The Radio Button is selected.")
    Else
        MsgBox ("The Radio Button is not selected.")
    End If
End Sub

And that's all there is to it.
