How to: Check If Current Row In dataGridView Greater Than Zero?

How many rows are there in the datagridview? Check the Row Count and remember it is zero based indexing so row 4 by human counting (1 based indexing) is index 3.

Probably because you're trying to use braces ({4}) instead of square brackets ([4]).

If not, click the "Improve question" link and post the missing details - in particular, the details of the error you're getting.

Please, post it as an answer and let notify me ;)

It's not clear whether that was the answer, or if it was Michael's suggestion that solved the problem. :)
