There is not much to the application I'm creating. Basically a RadDocking control in a user control what is being consumed into the content of a tab control. I get the following error, any ideas?

Webpage error details

Message: Unhandled Error in Silverlight Application
Code: 4004    
Category: ManagedRuntimeError       
Message: System.InvalidOperationException: UIElement.Arrange(finalRect) cannot be called with Infinite or NaN values in finalRect.
   at System.Windows.UIElement.Arrange(Rect finalRect)

   at System.Windows.FrameworkElement.ArrangeOverride(IntPtr nativeTarget, Single inWidth, Single inHeight, Single& outWidth, Single& outHeight)     

If I remove the docking stuff and replace it with a label, all is fine. here is the definition of my user control:

Hello Xav,

 As the exception says you cannot place the Docking control inside a control or panel that would measure it with infinite width or height. This could be a StackPanel, an Auto row or column of a Grid, ScrollViewer or something like this. You could work-this-around setting a Width and Height to the Docking control.

Miroslav, I followed your suggestion, so now I have:

        <telerik:RadDocking Name="radDocking1" Width="900" Height="760">

but that didn't help. Do I need to so the same for all sub controls like the RadSplitContainers? 

Thanks for your quick response

Miroslav,
  Setting the Height/Width properties on all RadSplitContainers eliminated the error- thanks!

  Can you recommend an approach to prevent my screen from being a static size? I'd like it to conform to the browser.

Hi Xav,

 The problem seems to be different than what I suspected. I tried your code at my side and found out that setting the TabStripPlacement property causes the problem. Once I removed its setters the problem was fixed.

Thanks for looking further Miroslav. Much appreciated.

Hi guys,
I know this thread is quite old already but thought sharing this would be of some interest.

My scenario was pretty similar of Xav's one as I embedded a RadTabControl into a RadPaneGroup.
I faced similar issue ...
Quite similar actually as I didn't have any runtime unhandled error but my Tabs simply didn't worked. they just highlight without releasing selection of previous tab.

I followed Miroslav's advice and got rid of my TabStripPlacement in the xaml, now seems to work fine...funny thing is that if I set that TabStripPlacement in the code behind (which I need to as want to give some liberty to my end user to customize his page) it's also working ...

Now question is did you find a permanent fix for this? Would be curious to know to understand this bug but right now don't have much time to investigate more ...

thanks anyway
Regards
Jim

Hi jean-Marc,

 We believe that the problem is due to the fact that TabStripPlacement is done using the LayoutTransform control and it gets messed in some sophisticated scenarios with RadDocking. It also has some flows with the Selection mechanism of both. We have this logged into our system and should fix it, but at the moment I can't give you exact date.
Sorry for any inconvenience. 

All the best,

Hi Sanjay,
