Simple IdeaBlade sample Application.

I used an UltraGridBindingManager, Added 4 Columns, "Name, "Last Name", "Country", "Race".

Set the UltraGridSource and run, showed me a few rows, I dragged Race column to the group by region, same exception.

Then I removed the "Race" column from GridBindingManager and added it using SortedColumns.Add(....) .. worked fine.

The thing I understand is it produces exception if the column is present in UltraGridManager, and in case of dragging its always present.

My Infragistics Grid has few columns binded using UltraGridBindingDescriptorTypeConverter.

When I use the Groupby option using either drag and drop orprogrammitcally using SortedColumns.Add ... it throws an InfragisticsException.

Error in custom data filter: Convert(...) throws an exception. Innerexception is: Object reference not set to an instance of an object.
  Exception(DataFilterException): Source="Infragistics2.Win.v7.2"; Target=null; Tag=null;
    Message = "Error in custom data filter: Convert(...) throws anexception. Inner exception is: Object reference not set to an instanceof an object."
    InnerException(NullReferenceException): Source="Infragistics2.Win.UltraWinGrid.v7.2"; Target=null; Tag=null;
      Message = "Object reference not set to an instance of an object."
      StackTrace =

             atInfragistics.Win.EmbeddableEditorBase.UpdateDataFilterCache(ConversionDirectiondirection, Object sourceVal, Type destinationType,


Can you Help? I saw this group by thing working,either in previous version of Ideablade or the same. I recently updatedto Ideablade 3.5.5.1,

Infragistics v7.2. is what I am using.
Thanx :).

Am Using Infragistics grid, I add binding descriptors to the grid.
When I use the group by option of that Grid, it throws exception. It works fine If either I dont use descriptors or not register that particular column as descriptor to the grid and group by it programmitcally.

Any suggestions?
