If I understand you correctly, you can call the .Clear method of the
datatable object its bound to. that will eliminate all of the rows and the
grid will be empty. Is this what you meant?

Hi Ryan

Actually i don't want my DataGrid to get empty. I want to reset the value in
the cells (or values held in the datatable) to 0 (Zero). On click on button
it should change all the values to 0.

Job,

You never can set a value in a datagrid (windowforms) to zero when the
underlaying datasource has another value than zero.

So when you want what you ask you have to set that field to zero. You can
reset a datarow by the original state (last filled) with
datarow.rejectchanges

I hope this helps?
