OnBeforeDragSizeGrip Method

Raises the BeforeDragSizeGrip event before the drag of the size grip for the UltraStatusBar begins

Syntax

Visual Basic

'Declaration
 
Protected Overridable Sub OnBeforeDragSizeGrip( _
   ByVal e As CancelEventArgs _
) 

C#

protected virtual void OnBeforeDragSizeGrip( 
   CancelEventArgs e
)

Parameters

e

A System.ComponentModel.CancelEventArgs that provides data for the event.

Remarks

Raising an event invokes the event handler through a delegate.

The OnBeforeDragSizeGrip 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 OnBeforeDragSizeGrip in a derived class, be sure to call the base class's OnBeforeDragSizeGrip method so that registered delegates receive the event.

Example

The following sample code illustrates what information is available in the BeforeDragSizeGrip event.

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.
