[Solved] RadGridView - filters - MVVM

[guillaume]

Hi,
I choose a filter on a RadGridView ( img1.png) ,
I save the filter (xml file) ,
and I close the application.

When I open the same file, I load my backup :

private void FillFilter<T>(QueryableCollectionView collection, ObservableCollection<T> filters)
       {
           foreach (T item in filters)
           {
               collection.FilterDescriptors.Add(new FilterDescriptor(
                   "Code",
                   FilterOperator.IsEqualTo,
                   item.GetType().GetProperty("Code").GetValue(item, null).ToString()
                   , true));
           }
       }

It display the good result but my filter(s) do(es) not appear in the column (cf. img2.png)


Is there a way to display the filters in the column?
Thanks.

Hi guillaume,

You need to use the ColumnFilterDescriptor instead of the FilterDescriptor in this case.

Ok thanks for the answer, but I develop with MVVM...

I use a QueryAbleCollectionView in my "ViewModel" and I binds it to a RadGridView which is in my "View".

I do not have access to a RadGridView, just to a QueryAbleCollectionView :(

Hello guillaume,

I suppose you will still need to write some code to achieve what you want.

How come that RadGridView among other controls from Telerik is not working with MVVM?!? This is really FUNDAMENTAL!
