Does the gridview have (at least) 11 columns and (at least) 1 row?

This means you are trying to access something that does not exist. What exactly is your question then?

The error means that either there are now rows and therefore .Rows[0] is null or There are not that many cells in your row.

Note, the cells will be zero based so perhaps Cells[10] does not exist.

However, this is a very easy thing for you to fix on your own if you just debug the code. Put a breakpoint on the code and you can see exactly what the problem is and how to fix it.

Pay attention to which line of code actually causes the error and then you'll know.

Solution 2

The grid cells index starts from zero, so probably if your table contains 10 columns, then your grid columns should start from cells[0] to cells[9].
