GridGroupingControl Problem : URGENT

Hi,
I'm using a GridGroupingControl that is bind with a Custom BindingSOurce (binded to a bindinglist) inherited from a BindingSource. I'm also using a custom notification of Changes in the list by using the SimulateListChanged method. I have a timer that send 200/300 notifications ItemChanged to the grid each second.

Everything works fine.

The problem is when I group the grid by column and I change the sort between two columns of different type, the grid throw an exception :

System.ArgumentException: Object must be of type Int32.
at System.Int32.CompareTo(Object value)
at Syncfusion.Grouping.Internals.SortColumnComparer._Compare(Object x, Object y)

Is there a way to correct this, or what can I do to prevent this problem.

Thanks
Simon.
