You error has nothing to do with colors and all that stuff. Error must be at first line of your code.That is:

int esal = int.Parse(e.Row.Cells[3].Text.ToString());

Replace this with below code:

C#

int esal= string.IsNullOrEmpty(e.Row.Cells[3].Text) ? 0 : int.Parse(e.Row.Cells[3].Text);

Then check the value which you tried to convert to int. The reason i provided this is,in your code,if you have empty text that is e.Row.Cells[3].Text as empty string than it will throw an error.If you use mine,then it will take 0 whenever there is empty string. If you still get an exception,its clear that the value in e.Row.Cells[3].Text is not valid to be converted to int.
