So, what is the content of txtquantity.Text?

[no name] 25-Nov-11 1:13am

integer, maybe?

If the txtquantity text is insteadof numeric, it will always disaply such error.
So make sure that your input is in correct format.

My 5 for "TryParse" suggestion.

thank you very much.

This is right API to use, but it won't help OP as the issue is the argument of TryParse or Parse. OP needs to check the value, use Debugger, get understanding of what's going on. If OP replace Convert with TryParse, the result will be the same, only without exception which was suggestive. :-<

Solution 1

First of all make sure that text box contains a value.. In case of null value it also shows that. Then make sure that it contains proper integer value.
I think it can help you.
