GeneralHere is a tough one - DataGrid throwing exception while repainting Pin

Luis Alonso Ramos25-Sep-02 8:25 
I have this code in my Clear() routine:

ds.Tables[0].Rows.Clear();
grdProducts.Refresh();


ds is an in-memory DataSet, not associated with any database, a simple way to access what's in the DataGrid. grdProducts if of course a DataGrid.

The problem is that most of the times I run this code there's an unhandled NullReferenceException exception ("Object reference not set to an instance of an object").

Looking at the stack trace, it happens when the DataGrid is painting itself (after a WndPaint event). If I omit the grdProducts.Refresh() call in my code, I don't see any of my functions in the stack trace, but adding it makes the function in progress appear several levels down the trace (obvious).

Any ideas??
