HTML Report sub-string

Question

I have an html report. I am to remove a string coming two times in this report. Please help. My code is as follows.

private void ShowEarnCard(string GrdNo, int Year)
{
PAY_REPORTSs objPAY_REPORTSs = new PAY_REPORTSs();
objPAY_REPORTSs.EarnCard_Pension(GrdNo, Year);
if (objPAY_REPORTSs.Count == 0)
{
Util.ShowNotification(this, "No Data Found");
return;
}

tt.BorderWidth = Unit.Point(1);

tt.CellPadding = 0;
