Unbound Column Exception
posted

I have attached a simple project recreating my scenario.

Version : 10.2.20102.2005

When I click into different cells back and forth I get an unhandled exception

"Operation is not valid due to the current state of the object"

More of the exception information:

System.Windows.Data.BindingExpression.UpdateSource()
   at Infragistics.Controls.Grids.CellControl.EvaluateEditingBindings()
   at Infragistics.Controls.Grids.Cell.ExitEditMode(Object newValue, Boolean editingCanceled)

   at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)

Please Help!
