Using the xamDockManager™ control, you can hide a pinned content pane by unpinning it. Likewise, you can pin a hidden pane when it flies out so that it is always visible. A content pane can be pinned and unpinned in code or by the end user at run time.
The following example code demonstrates how to unpin a content pane.
In XAML:
...
<igDock:XamDockManager Name="xamDockManager1">
<igDock:XamDockManager.Panes>
<igDock:SplitPane>
<igDock:ContentPane
Name="contentPane1"
Header="Pane 1"
IsPinned=">
<!--TODO: Add content here-->
</igDock:ContentPane>
</igDock:SplitPane>
</igDock:XamDockManager.Panes>
</igDock:XamDockManager>
...
In Visual Basic:
Me.contentPane1.IsPinned = False
In C#:
this.contentPane1.IsPinned = false;
