Accessing The Label Inside The GridView RowDataBound

 If I have a Label (lblAmount) in my GridView's TemplateField, one of the simplest way to access it and modify its format is shown below:

if (e.Row.RowType == DataControlRowType.DataRow)
    {
            Label myLabel = (Label)e.Row.FindControl("lblAmount");
            string newLabelFormat = myLabel.Text;
            const string fmt1 = "#,##0.00;(#,##0.00)";
            double newAmountFormat = Double.Parse(newLabelFormat);
            string myAmountFormat= newAmountFormat .ToString(fmt1);
            newLabelFormat = myAmountFormat;
            myLabel.Text = newLabelFormat;
      }
