DataGridViewColumn.Visible=False is being ignored.

Hi All,

I have a DGV with many columns bound to a binding source and I've set the DataGridViewColumn.Visible property to False for several of the columns including the first column. At design time, the first column is not visible, but when I run the program, the first column is visible. I see this problem intermittently but don't know what's going on. Does anyone know what's going on here?

Thanks,

Andy Moyer
