Yes - the exception message can tell you. My guess is that the Text property is either empty or not a number of one of the cells. You need to include the error message to get better help!

Solution 5

"Input string was not in a correct format".
This simple means that the value of GridView1.Rows[i].Cells[0].Text is not an integer and hence when you are trying to convert it, it throws an exception.

All you need is to put a DEBUG point and see it by yourself using Visual Studio debugger.

Correct, my 5. What to do with it is a different problem.

Thanks SA.

Exactly the reason why I replied, wamted to tell root cause which none of the answer covered.

Yes, this is the only answer I would accept on this page (at the time of my first comment).
