  Modify your data source for GridView before assigning to it, and use ColumnSpan in RowCreated or RowDataBound event if underlying DataItem is blank. To modify DataSource, just loop through the data source and check current data row with previous value and if both Date and Dc No matches then modify that data source row with blank value.

  And further as I said, use ColumnSpan in RowCreated or RowDataBound event if underlying DataItem is blank.

  hope that helps./.
