I need to call the
..Rows.Refresh(RefreshRow.ReloadData);

method for a grid on another form because the datable that it is attached to
is updated on the backend and since my application is MDI the user wants to
see the changes applied if they change a value of a cell in another grid
which is on another form. Values in the other grids on the other forms are
used in a calculation to display the resutls in the grid in question.

To make it easy,

Grid1 on form1

grid2 on form2

grid3 = (grid1*grid2) on Form 3

so if changes happen on grid 1 or grid 2 we need to immediately update
grid3.
