public:
 void OnSplitterMoving(System::Windows::Forms::SplitterCancelEventArgs ^ e);

public void OnSplitterMoving (System.Windows.Forms.SplitterCancelEventArgs e);

member this.OnSplitterMoving : System.Windows.Forms.SplitterCancelEventArgs -> unit

Public Sub OnSplitterMoving (e As SplitterCancelEventArgs)

Parameters

e: SplitterCancelEventArgs

A SplitterEventArgs that contains the event data.

Examples

The following code example raises the SplitterMoving event, signified in this example by a change to the cursor style when you move the splitter. The SplitterMoved event is raised when you stop moving the splitter. This is signified in this example by the cursor style reverting to the default.

Remarks

The SplitterMoving event is raised while the splitter is in the process of moving. After the SplitContainer has moved, use the SplitterMoved event and the OnSplitterMoved event handler.

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
