Binding RadDocumentPanes to a collection

[Dennis]

We are trying to bind a collection of items to a set of RadDocumentPanes through the ItemsSource & SelectedItem properties on the RadPaneGroup control. Unfortunately we were unable to create viable documents in this manner, and had to create a custom converter to return our items wrapped as RadDocumentPanes. Is this a limitation of the Rad control or is there a better way to do this?

Hello Dennis,

 Unfortunately this is not supported by the RadPaneGroup control. If you need to add and remove items from a RadPaneGroup you will need to use the Items collection instead.

Is this going to be addressed going forward? I was looking into how you can bind the RadPaneGroup to a collection of RadPanes that is populated by MEF via a View model. I don't want to start putting stuff in the code behind for the view. Are there any other ways of achieving this in the meantime?

Thanks

Hi Matt,

 We are not planning to add this functionality directly to the PaneGroup as it is not supported by design. What I could suggest you is to implement custom attached property that will allow you to achieve this. Please find the attached project.

Hi Miroslav,

I am having a similar requirement for myself and I tried out the sample provided by you. The one problem I am facing with your example is that if i close a particular RadPane using the Close (X) button at the top right of the RadPane and then try adding a new RadPane, it throws a ArgumentOutOfRangeException. I guess this is due to the reason that, the ItemSource of the RadPaneCollection is not aware of that one item is removed from the collection when the close button is clicked. How do we achieve this?

Any help is appreciated.

Thanks

Hi Syam,

 You might work this problem around by postponing the operation using Dispatcher.BeginInvoke.

Hope this helps.

Hi,

Has there been any further updates or simplifications since the post containing the attached solution on 29 April 2010? I'm finding the attached project difficult to wrap my head around, and there seems to be parts in the attached project that require further work or that I need to modify myself.

Thanks

Hello Peter,

Please, refer to the following forum thread about using the RadDocking control in MVVM scenarios - http://www.telerik.com/community/forums/wpf/docking/data-templates-and-mvvm-support.aspx where you can find more information.

Hope this helps.
