SplitContainer.OnMouseUp(MouseEventArgs) Method

protected:
 override void OnMouseUp(System::Windows::Forms::MouseEventArgs ^ e);

protected override void OnMouseUp (System.Windows.Forms.MouseEventArgs e);

override this.OnMouseUp : System.Windows.Forms.MouseEventArgs -> unit

Protected Overrides Sub OnMouseUp (e As MouseEventArgs)

Parameters

Remarks

By default, the OnMouseUp event handler allows the user to track the splitter position while it is moved up with the mouse. OnMouseUp also draws the SplitterRectangle to show the current position of the splitter while it is moving. The SplitContainer keeps track of the initial SplitterDistance in case the user cancels the move.

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

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