Of course your code wont work because simply you telling the program to get the sum of the first row first cell and second row second cell etc...
and in one point you will get an error if your rows are more than your columns
you need to add another for loop to loop over the cells in each row this is how its going to work

Hope this helped

Solution 2

The better way to do this would be to

1. have a form level variable to store the sum,
2. initialize it to 0
3. and then in RowDatBound event add the current rows value into this member variable.

When the grid is bound this varable will contain the sum.

4. you can put this value in a textbox in unlod event.
