I think we are not understanding each other.

this is my situation, I have a DataGridColumnStyle Class with a TextBox and a Button, in the class i add a Handler to the DataGridColumnStyle.TableStyle.DataGrid.Scroll, this handler hide the TextBox and The Button when the grid is scroll.

what i want is from a event in a form force the DataGrid to call the Scroll event to disapear the TextBox and The Button, but i don't want to add a Method to the DataGridColumnStyle Class to do That.

I found this ISystemDebugEventFire.FireEvent in The MSDN but i don't know how to use.
