Filter not working on RadGridView bound to DomainDataSource

[HDC]

I got following grid definition :

<telerik:RadGridView x:Name="RssFeedsGrid"
                     ItemsSource="{Binding RssFeeds}"
                     AutoGenerateColumns="False"
                     IsReadOnly="False"
                     IsBusy="{Binding IsBusy}"
                     ShowGroupPanel="False"
                     Grid.Row="0"
                     CurrentItem="{Binding CurrentRssFeed, Mode=TwoWay}"
                     telerik:RadDragAndDropManager.AllowDrop="True"
                     BorderThickness="0"
                     Padding="0"
                     Margin="0"
                     DataLoading="RssFeedsGrid_DataLoading"
                     Background="Transparent"
                     >
</telerik:RadGridView>

It's bound to a viewmodel that is a singleton using following code:

this.DataContext = ViewModels.ExqiRssFeeds.RssFeedsParentViewModel.Instance;

 

The collection RSSFeeds is defined as follows:

public QueryableDomainServiceCollectionView<ExqiFramework.Shell.Web.RssFeed> RssFeeds
    {
      get
      {
        return this._rssFeeds;
      }
      set
      {
        _rssFeeds = value;

        this.OnPropertyChanged("RssFeeds");
      }
    }

Data for RssFeeds is loaded using following code:

EntityQuery<ExqiFramework.Shell.Web.RssFeed> getRssFeeedsQuery = this._ExqiPresenterDomainContext.GetRssFeedsSortedQuery();            
this.RssFeeds = new QueryableDomainServiceCollectionView<ExqiFramework.Shell.Web.RssFeed>(this._ExqiPresenterDomainContext, getRssFeeedsQuery);      

All of this works for loading data, but when i apply a filter to any of the columns, nothing happens.

Am i missing something?
 
Do i need to handle myself the filtering events and if so how do i do that with a viewmodel?

Best Regards,

Hello,

You do not need to do anything manually.

Can you please take a look at the sample project from my blog post? There filtering works as expected.

Also, take a look at this online example. Filtering works as expected out of the box.

Hi Ross,

I have double checked and it just isn't working for me.

Nothing happens when a filter is clicked.

Finally figured it out... this was caused by the type of collection i was binding to... don't bind a grid to a QueryableDomainServiceCollectionView object... it will not work.

I solved it by just pumping over the colection to a ObservableCollection.
