Error In simple task???? gridview

[John]

Why does this simple task not work on radGridView when the FilterMode is FilterRow?

I put the test code below behind a button click event for what I thought was a simple 5 minute test.

Data is loaded, grid is looking good, then I click the button

 

FilterDescriptor Test = new FilterDescriptor();

 

Test.Value = "ABC";

Test.Operator = FilterOperator.StartsWith;

Test.Member = "COLUMNNAME";

 

GridTest.FilterDescriptiors.add(Test); <------------- EXCEPTION

 

This throws and exception with message "The method or operation is not implemented"

I have implemented the provided code snippet in a sample application, in order to reproduce the mentioned exception, however, I was unsuccessful. On my end, when the above code snippet is executed on a RadButton's Click event, the newly created FilterDescriptor is correctly applied, and the RadGridView control is filtered. 

With that said, I have attached the test application, so, could you give it a try and let me know if I am missing something?
