We are attempting to activate (focus) a RadPane by setting a bound IsActive property.
The set results in a InvalidOperationException, indicates IsActive is a read-only property.
The documentation seems to suggest this as a workable approach,
(bottom of http://www.telerik.com/help/silverlight/raddocking-panes-radpane.html
but Object Browser indicates that IsActive has no public setter (we are using Q3 2013).
Should we be able to set IsActive and thereby cause a RadPane to become focused?
