Binding SortDescriptors

[haagel]

I'm using the MVVM pattern for my application.

 

Is it possible to bind the SortDescriptors collection of a RadGridView to a list in my viewmodel, and if so how do I do that?

 

Creating a property of type SortDescriptionCollection in my viewmodel is easy, but I don't know how to bind the gridview to that.

 

Thanks // David

Hello David Haglund,

 You can do two things: you can either expose your data through a property of type QueryableCollectionView on your ViewModel, which has SortDescriptors, GroupDescriptors, etc., which will be directly used by the RadGridView and which you can modify yourself from your ViewModel, or you can adapt this approach to your scenario.

Hi Yavor!

Let me see if I understand you correctly...

This QueryableCollectionView... should I have a property of that type in my viewmodel and bind the ItemsSource of the gridview to that?

Your other solution, the one in the blogpost, also seems interesting. :)

Hello David Haglund,

 Your understanding is correct, that is exactly how it is used in this scenario.
