System.NullReferenceException while setting data source in UltraWinGrid.v8.2
posted

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.

    I realize I'm sort of reopening an old thread, but I had a similar issue and discovered with the help of this StackOverflow thread that I'd somehow blown out the InitializeComponent() call in my constructor. Adding it back fixed the problem.
