Close RadPane Instances
Each RadPane is closable by default via the Close button or the Hide menu item shown on the snapshots above.
You can also hide/show your RadPane instances programmatically using the boolean RadPane's property IsHidden. When a RadPane is closed it is actually hidden and you can always make it visible again when needed.
When you set the IsHidden property of a RadPane to True or close it, it is actually removed from the visual tree.
Example 1: Set IsHidden
<telerik:RadPane x:Name="radPane" IsHidden="True"/>
Example 1: Set IsHidden
radPane.IsHidden = true;
radPane1.IsHidden = True

<!-- ... -->
</telerik:RadPaneGroup>
Example 2: Set CloseTabsOnMouseMiddleButtonDown
