Occurs when the value of the Checked property changes.

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