RadioButton.CheckedChanged RadioButton.CheckedChanged RadioButton.CheckedChanged RadioButton.CheckedChanged Event

Definition

Occurs when the value of the Checked property changes.

public:
 event EventHandler ^ CheckedChanged;
public event EventHandler CheckedChanged;
member this.CheckedChanged : EventHandler 
Public Custom Event CheckedChanged As EventHandler 

Examples

The following code example demonstrates how the CheckAlign property can be changed at run time. The check box portion of a RadioButton is moved to the right or left of the text when the Checked value changes. This example requires that a RadioButton control has been instantiated on a form and that a reference to the System.Drawing namespace has been included.

private:
   Void radioButton1_CheckedChanged( System::Object^ sender,
      System::EventArgs^ e )
   {
      // Change the check box position to be opposite its current position.
      if ( radioButton1->CheckAlign == ContentAlignment::MiddleLeft )
      {
         radioButton1->CheckAlign = ContentAlignment::MiddleRight;
      }
      else
      {
         radioButton1->CheckAlign = ContentAlignment::MiddleLeft;
      }
   }
private void radioButton1_CheckedChanged(Object sender, 
                                         EventArgs e)
{
   // Change the check box position to be opposite its current position.
   if (radioButton1.CheckAlign == ContentAlignment.MiddleLeft)
   {
      radioButton1.CheckAlign = ContentAlignment.MiddleRight;
   }
   else
   {
      radioButton1.CheckAlign = ContentAlignment.MiddleLeft;
   }
}

Private Sub radioButton1_CheckedChanged(sender As Object, e As EventArgs)
    ' Change the check box position to be opposite its current position.
    If radioButton1.CheckAlign = ContentAlignment.MiddleLeft Then
        radioButton1.CheckAlign = ContentAlignment.MiddleRight
    Else
        radioButton1.CheckAlign = ContentAlignment.MiddleLeft
    End If
End Sub
