[tyrem]

I am using this query:\[code\]select EmployeeId, receptionist_name, date_of_sale, count(date_of_sale) from FrontOffice group By EmployeeId, receptionist_name, date_of_sale order by date_of_sale\[/code\]for filling the grid view. But I can bound the \[code\]EmployeeId\[/code\], \[code\]receptionist_name\[/code\], \[code\]date_of_sale\[/code\], so can you tell me how can I bound the 4th column in grid view and how to fill the grid view.and grid view bind code is
