Examples
The following code example demonstrates how to override the OnClick method. This code example is part of a larger example provided for the ToolStripItem class.
// The method defines the behavior of the Click event.
// It simply toggles the state of the clickedValue field.
protected override void OnClick(EventArgs e)
{
base.OnClick(e);
this.clickedValue ^= true;
}
' The method defines the behavior of the Click event.
' It simply toggles the state of the clickedValue field.
Protected Overrides Sub OnClick(e As EventArgs)
MyBase.OnClick(e)
Me.clickedValue = Me.clickedValue Xor True
End Sub
Remarks
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnClick method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnClick(EventArgs) in a derived class, be sure to call the base class's OnClick(EventArgs) method so that registered delegates receive the event.
