[Solved] Grid asynchronous interaction

[Phillip Garrett]

Hi,

My senario:
I have a RadGridView whos DataContext is a separate ViewModel. I bind the RadGridViews ItemsSource to an ObservableCollection in the ViewModel. I then have several GridViewComboBoxColumns & GridViewDataColumns.
I populate the ObservableCollection with data from a WCF service. When I recieve a completed event from a asynchronous call to that service I clear the ObservableCollection and re-populate with the new data.

My problem:
The RadGridView loading animation generated automatically because I have DataLoadMode set to Asynchronous appears, but the animation freezes. Furthermore any other animations I create freeze up while the RadGridView updates its ItemsSource bindings.

Do you have any advice on how I can use RadGridView so that the user can still interact with items / see animations while ItemsSource is being updated?

Thanks
Phill

Hi,

 Since your binding (WCF service) is asynchronous itself you do not need the grid asynchronous mode. If you want you can bind IsBusy grid property to your model relevant property to show the busy animation similar to this demo. 

Kind regards,
