I want to sum GridView column value with a variable and show the result in second column. I am trying to do this.But when I convert the GirdView column into an integer the following
"Input string was not in a correct format." Error is occuring.
Please help.
Here is my C# code:
for (int i = 0; i < GridView1.Rows.Count; i++)
{
long sum = openingBalace + Convert.ToInt64((GridView1.Rows[i].Cells[6].Text));
GridView1.Rows[i].Cells[8].Text = sum.ToString();
}
Thanks
