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?

My Infragistics Grid has few columns binded using UltraGridBindingDescriptorTypeConverter.

When I use the Groupby option using either drag and drop or programmitcally using SortedColumns.Add ... it throws an Infragistics Exception.

Error in custom data filter: Convert(...) throws an exception. Inner exception 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 an exception. Inner exception is: Object reference not set to an instance of 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 =
          "   at Infragistics.Win.UltraWinGrid.EmbeddableEditorOwnerInfo.GetExternalContext(Object ownerContext)
             at Infragistics.Win.EditorDataFilterConvertArgs.get_Context()
             at IdeaBlade.UI.WinForms.InfragisticsControls.UltraDataFilter.Convert(EditorDataFilterConvertArgs pConvertArgs)
             at Infragistics.Win.EmbeddableEditorBase.UpdateDataFilterCache(ConversionDirection direction, 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 updated to Ideablade 3.5.5.1,

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

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.
