>>>I am new to grids. I have a form in which I have a 9 column grid. But when the form is run, the Grid shows 10 column (i.e one additional unwanted column at extreme right). Please see the attached Screen shot.

>>No 10 column. It is unused area. Reduce the width of the grid.

>Thanks. But sir I have kept the width of Grid up the 9 columns only. Not a single extra width has been kept beyond the 9th column.

Reduce the width of the whole grid.
