If you want to enable or disable the button document.getElementByID('btnEdit').disabled = true; //disable the button document.getElementByID('btnEdit').disabled = false; //enable the button In server side btnEdit.Enabled = true; and btnEdit.Enabled = false; While page index the selection has to be stored in the memory or some hidden control then it needs to checked.
