Hi Chris,
The error is at runtime. It says "object not set to an instance". I know
the grid is not the problem as I can see it after it is populated.
I think it refers to the TableStyles object within the Grid. I Added the
following line to verify:
int nStyles = oGrid.TableStyles.Count;
nStyles value is zero. I was expecting a value of 1 as the grid was
populated from a table.
Just in case you are wondering, the column formatting setGridColumnStyle()
is called after the grid is populated.
Any Ideas?
Thank you,
Carlos Lozano
