Occurs when the user changes the docking position of the active custom task pane.
Note
Custom task panes can be created in any language that supports COM and allows you to create dynamic-linked library (DLL) files. For example, Microsoft Visual Basic 6.0, Microsoft Visual Basic .NET, Microsoft Visual C++®, Microsoft Visual C++ .NET, and Microsoft Visual C#®. However, Microsoft Visual Basic for Applications (VBA) does not support creating custom task panes.

Syntax

expression.DockPositionStateChange(CustomTaskPaneInst, )

expression An expression that returns a CustomTaskPane object.

Parameters

Name Required/Optional Data Type Description
CustomTaskPaneInst Required Object The active custom task pane.

Example

The following example, written in C#, creates a custom task pane and adds a Microsoft ActiveX button control that was created in another project. A DockPositionStateChange event of type _CustomTaskPaneEvents_DockPositionStateChangeEventHandler is then defined. When the event is triggered, a message box is displayed telling the user that the docked task pane has been moved.

C# 
object missing = Type.Missing; public CustomTaskPane CTP = null; public void CTPFactoryAvailable(ICTPFactory CTPFactoryInst) { CTP = CTPFactoryInst.CreateCTP("SampleActiveX.myControl", "Task Pane Example", missing); sampleAX = (myControl)CTP.ContentControl; sampleAX.InsertTextClicked += new InsertTextEventHandler(sampleAX_InsertTextClicked); CTP.Visible = true; CTP.DockPositionStateChange += new _CustomTaskPaneEvents_DockPositionStateChangeEventHandler(CTP_DockPositionStateChange); } private void CTP_DockPositionStateChange(object sender, string dockpositionArgs) { Console.WriteLine("The custom task pane was moved"); }
