Hi,

I am getting the following error while setting the datasouce of the Wingrid. The error is sporadic. The data source is a list of business objects. 

The line of code is : grid.DataSource = dataSouce;

The error seems to occur when the grid is bound to a list of objects and I try to rebind the grid with a new list of objects (typically I need to do this when there is a new item to be added to the list).

When I inspect this list (of business objects), everything looks okay. None of the objects themselves are null.

I would appreciate any help. Thanks.

System.NullReferenceException was unhandled
