I have used datagird to loading data , When I set up one cloumn with checkboxSelectColumn and set up "headertext=select all"" ,But run this page, this grid didn't display headertext,only a checkbox in head.
Please help me to tell me how to solve this problem. thanks a lot.
I guess you want to give HeaderText for the GridClientSelectColumn. Please try adding a label to the headeritem for the clientselectcolumn as shown in the code below.
