Examples
The following code example demonstrates how to override the OnDoubleClick method. This code example is part of a larger example provided for the ToolStripItem class.
// The method defines the behavior of the DoubleClick
// event. It shows a MessageBox with the item's text.
protected override void OnDoubleClick(EventArgs e)
{
base.OnDoubleClick(e);
string msg = String.Format("Item: {0}", this.Text);
MessageBox.Show(msg);
}
' The method defines the behavior of the DoubleClick
' event. It shows a MessageBox with the item's text.
Protected Overrides Sub OnDoubleClick(e As EventArgs)
MyBase.OnDoubleClick(e)
Dim msg As String = String.Format("Item: {0}", Me.Text)
MessageBox.Show(msg)
End Sub
Remarks
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnDoubleClick 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 OnDoubleClick(EventArgs) in a derived class, be sure to call the base class's OnDoubleClick(EventArgs) method so that registered delegates receive the event.
