How To Know DocumentHost is Empty

[Kelly]

I have some RadRibbonContextualGroups in a RibbonView. I'd like to bind their IsActive props to something in a RadDocking that shares the same window. I'd like IsActive to be false when the Docking's DocumentHost is empty, and true if there is at least one pane in the DocumentHost. Can this be done through bindings?

Thank you,

Hi Kelly,

The best way to achieve this is to cast the DocumentHost to RadSplitContainer, enumerate its panes and check if there are any panes that are not hidden. Here is sample code:

bool hasVisiblePanes = ((RadSplitContainer)this.Dockings.DocumentHost).EnumeratePanes().Any(x => x.IsHidden == false);

For the binding you can use a TypeConverter and use the code above.

Hope this helps.
