RadioButton::CheckedChanged Event

Occurs when the value of the Checked property changes.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public:
 event EventHandler^ CheckedChanged {
	void add (EventHandler^ value);
	void remove (EventHandler^ value);
}

For more information about handling events, see Consuming Events.

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;
      }
   }
