Simple sample does not work

[andrew rekvils]

I am trying to combine RadDocking and RadTreeView as it published in simple sample. My user control loads just fine if I have either RadDock or RadTreeView but not both. When I add radTreeView to RadPane I get an error that I can see from the frowser status bar that reads "... SysInvalidOperationException. InitializeError error #2101 in control 'Xaml1': Failed to initialize the application's root visual". Here is complete XAMl of my control.

Thank you,
Andrew

Hello andrew rekvils,

Do you have reference to the following assemblies: Telerik.Windows.Controls, Telerik.Windows.Controls.Navigation and Telerik.Windows.Controls.Docking in your project?
They are need in order to run Docking example.

Hristo,

Yes, I have referenced to all three assemblies. As I wrote in my message if I have only one control (either RadDocking or RadTreeView) on my user control then each of them shows just fine which proves that I do have all required assembly references. The error happens only if I have both controls inside the same user control. I also noticed yesterday that if I place RadTreeView inside RadDocumentHost element RedTreeVew shows up, but not if it is inside RadPanel. XAML code attached to original message is exact content of my user control that does not work.

Thank you,
Andrew

Hello andrew rekvils,

Could you send us project demonstrating this error so we can investigate it further.
I was able to build your xaml without any modification and there is RadTreeView in the right pane.

Hi Carlos Alberto,

The code you sent doesn't present any errors. If it shows any errors to you, the problem might be in the references in your project. Also I see in your code something that is not correct - you have a TabControl just in the RadDocking and this is not correct. If you want to create something that looks like documents in visual studio you need to put your content in the DocumentHost of the RadDocking. Here is an example:

<radDock:RadDocking.DocumentHost>
    <radDock:RadSplitContainer>
        <radDock:RadPaneGroup>
            <radDock:RadPane Header="pane 1" Content="some content" />
            <radDock:RadPane Header="pane 2" Content="some content" />
            <radDock:RadPane Header="pane 3" Content="some content" />
            <radDock:RadPane Header="pane 4" Content="some content" />
        </radDock:RadPaneGroup>
    </radDock:RadSplitContainer>
</radDock:RadDocking.DocumentHost>

Please, let us know if have some troubles. If you still have problems, please open a support ticket, attach your project and write the error that you get.
