Error is occuring while debugging

Hi,

I think this error is happen when your lbleno.Text does not contains any values and you parse it. Use below code.

if (!string.IsNullOrEmpty(lbleno.Text))
{
int eno=int.Parse(lbleno.Text);
}
else{
// write here error message which you want.
}

By looking at the code (Label lbleno=(Label)row. FindControl("lblempno"); ) posted here, everything seem ok. But I'm not sure how your GridView being designed or where it being called. I would check to make sure the "lblempno" match the aspx markup, it case sensitive.

Here some links that might give youo more insight.
