I think what he meant was that when you modify the RadGridView.FilterDescriptors directly the Filtered event for the GridView is not fired. I have just encountered that bug now with Telerik controls version 2010.1.412.1030

In my case, the following code would not fire the Filtered event. (Assume that filters were added to the compositeDescriptor or that it's empty)
CompositeFilterDescriptor compositeDescriptor = new CompositeFilterDescriptor(); 
if (gv.FilterDescriptors.Count == 1) 
    gv.FilterDescriptors[0] = compositeDescriptor; 
else 
    gv.FilterDescriptors.Add(compositeDescriptor); 

It's not a big deal for me since I don't actually have to have that event, but I can see where it could be useful to fire that event even if the filters are modified programmatically.

Hi Francisco Amador,

That is not a bug. This is by design. The events are raised only when the end-user is using the UI to filter so you as a developer can respond to this. You have no other way of knowing that the user is clicking the filtering UI.

In case you are touching the filters programmatically, you are the one that is causing the filtering and thus you know what you are doing and you can take the respective action if needed. You do not need events in this case. I hope this makes sense.

Kind regards,

Yes it does. Like I said, I didn't really need it since I was making my own calls, but I just wanted to bring it up just in case.

Thank you for your clarification,
-Francisco
