RadTabItem :setting dataContext before Loaded event

[Marc-André]

Hi,

I'm using a RadTabControl with a different usercontrol inside each tabs.  Each user control has it's own viewModel.  Now I'm trying to assign the datacontext of a usercontrol BEFORE the tab has been Loaded (the user did not visit this tab).  Here is the code I'm using:

ucProjectLayoutV2 = new ProjectLayoutV2View();
ucProjectLayoutV2.DataContext = new VM.ProjectLayoutViewModel();

This works fine, except when the user navigates to the tabItem, it looks like my initialization is gone and a new usercontrol is created from scratch.  Am I misunderstanding something in the RadTabControl behavior?

Is there a way maybe to PreLoad all tabItems? Or maybe there's a better way to handle this... Please help me out.

Thanks

Marc

Hello Marc-André,

You can try handling the PreviewSelectionChanged event of the RadTabControl, but if you want you can send us your sample project so I will be able to help you better.

On a side note, I'd like to inform you that we've just released an online tool that allows you to reduce the size of your Silverlight applications. For more information, please visit http://blogs.telerik.com/blogs/posts/10-06-10/telerik_assembly_minifier.aspx
