Hello,
I have an Avalondock that incorporates both a LayoutDocumentPane and an LayoutAnchorablePane the DocumentsSource and AnchorablesSource both binding to the same datasource which in this case returns a collection of airport codes and airline codes.
![Image]()
What I have currently is when I check an airline code both the tab in the Document pane and also the tab in the Anchorable pane have style applied to change the background color of the tab.
What I have at the moment when checking the check box![Image]()
What I want is in addition to the background color of the tab being updated when I check a check box I want the appropriate document in the Anchorable pane to be the active content. In the example below the effect I need when checking the check box would be the same as clicking on the tab for LGW from the Anchorable pane, the data for LGW would show. Any pointers on how this could be achieved? Thank you.
What I really want when checking the check box![Image]()
Below is the XAML and code behind that I used
