Hi Edward, >>the same commands from outside of grid, for example from Click event of >>Command button, all goes just fine, the column goes away. >workarounds, e.g. you can even move focus out of grid programmatically and >fire some form method to delete a column. If for some reason, this will not >work either, then eventually you can make Column.Visible=.f. instead of This method gives you an weird results because you'll have a thick vertical line on the columns place, also it will give you the empty column when you'll try to hide the last column. I dunno why it happens by this way, but I've found (again right after posting question ;) the great workaround that is to have an Custom object with calling the appropriate DeleteColumn method. Works just fine.
