Hi,
I'm using the WPF RadGridView in an MVVM architecture.
My grid is sorted using a SortDescriptor defined on an "Order" property in XAML. The user is able to change the order using different ContextMenu Buttons. When I change the Order Property of the items in my ItemsSource, the changes are visible in the grid, but the sorting is not updated. Which means, the items are sorted in a wrong order.
How do I refresh the ItemsSource in my ViewModel? I do not want to aquire a reference to my RadGridView and call the Rebind() method.

Hello,

The filter will be automatically re-applied when the bound source collection raises CollectionChanged event. If the Action is Reset, the grid will re-create its entire view. It the Action is Add or Remove with a single item, the grid will evaluate its FilterDescriptors. So you could remove a data item, edit its Value property and then add it back to the collection again.
