I downloaded and used PureServerSideFiltering as my basis. If you look at my code you will see I created a view SSFiltering, and also added the necessary code to typeextension.cs and ssradCustomers.xaml...
I had to change some references, as they must have been for a previous version of silverlight, but it all executes now.
My question is that since you have the following code, that assumes autogenerated columns, what code do I use instead for the manual columns.
this.radGridView1.AutoGeneratingColumn += this.OnGridAutoGeneratingColumn;
private void OnGridAutoGeneratingColumn(object sender, GridViewAutoGeneratingColumnEventArgs e)
