Setting QDSCV FilterDescriptors

[Scott]

I have been setting filter descriptors like the following:

DDS.AutoLoad = false;
DDS.FilterDescriptors.Clear();
Telerik.Windows.Data.FilterDescriptor fd = new Telerik.Windows.Data.FilterDescriptor("Name", Telerik.Windows.Data.FilterOperator.Contains,
                                                                                         filter) { IsCaseSensitive = true };
DDS.FilterDescriptors.Add(fd);
DDS.AutoLoad = true;

and it used to work. I updated to 2011 Q2 SP1 and now when the filter doesn't find any records in the query it throws an exception (attached). I'm beginning to question the right way to programatically alter a field descriptor's value and was hoping you could tell me if the above way is correct or not. If not what would be the correct way of altering a filter?

Hello Scott,

I've tried to reproduce the reported exception, unfortunately to no avail.
I'm attaching my test application (requires Northwind database). Could you please take a look and let me know what I'm doing wrong?
Thank you in advance.

Thanks for the help Nedyalko.

All I needed to do is add a standard Silverlight DataForm to the MainPage.xaml like this.

<controls:DataForm Grid.Row="2" ItemsSource="{Binding DataView, ElementName=rdds}" />

If you want me to send you the broken project just email me.

Hi Scott,

I've managed to simulate the problem, and it is already fixed in our source code. The fix will be publicly available with next internal build (Monday 17 Oct).
Sorry for the inconvenience caused.
