protected:
 virtual void OnDoubleClick(EventArgs ^ e);

protected virtual void OnDoubleClick (EventArgs e);

abstract member OnDoubleClick : EventArgs -> unit

Protected Overridable Sub OnDoubleClick (e As EventArgs)

Parameters

e: EventArgs

An EventArgs that contains the event data.

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.
