Hi In a repeater it is displaying Date as - 01-01-0001. I want if Date is null / blank it should be displayed as "" htmlTable.Append(" " + Convert.ToDateTime(colum.GrpSessionStartDate).ToString("dd-MM-yyyy") + " "); Thanks

Try this: htmlTable.Append(" " + (column.GrpSessionStartDate != null ? Convert.ToDateTime(column.GrpSessionStartDate).ToString("dd-MM-yyyy") : "") + " "); Thanks

Hi Amit It is giving error Cannot convert from system.date.time? to string Thanks

Try this htmlTable.Append(" " + (String.IsNullOrEmpty(colum.GrpSessionStartDate) ? "" : Convert.ToDateTime(colum.GrpSessionStartDate).ToString("dd-MM-yyyy")) + " ");
