I’m using #master_checkbox and “Ch” for the each row.

The problem is :

When i click(check) the master checkbox …all the rows are selected(checked)…But when i uncheck any one row from the grid,master checkbox should uncheck…but its not unchecking the mastercheck box.Could you please help me in this issue…Please tell me how to uncheck the master checkbox when any row is unchecked from the grid.Advance thanks for your help!

Such functionality can be implemented by using next code snippet

          if (!state){   //unchecked
                // this code locates the HTML object of master checkbox, it expects that checkbox sits in second row of header
                var master=this.hdr.rows[2].cells[ind].getElementsByTagName(“INPUT”)[0];
          return true;
