Error occurs when row inserted via binding source into GridGrouping control

Hello,

I have a GCC bound to a Forms.BindingSource. When I insert a row via my DataBinding source, I get an exception on the grid grouping control. I call BindingSource.AddNew() a few times, and get the exception.

Here is the exception dialog contents:

An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in Syncfusion.Shared.Base.dll

Additional information: Count = 2 FilteredRecordCount = 0 YAmountCount = 2 ElementCount = 0 RecordCount = 0 CustomCount = 0 VisibleCustomCount = 0 out of range Count = 0 FilteredRecordCount = 0 YAmountCount = 0 ElementCount = 0 RecordCount = 0 CustomCount = 0 VisibleCustomCount = 0

Thanks for your help on this,
-Mike
