create a bool variable(isCheckBoxSelected) and set it to False before foreach.. inside foreach, if (cb.Checked == true) set isCheckBoxSelected variable to True.. after foreach loop, check value of isCheckBoxSelected , if it is still false, display your message..

use this javascript function CheckBoxClicked(chk) { var dl = document.getElementById (" "); //Replace DatList1 with your DataList ID var inputs = dl.getElementsByTagName("input") ; for(var i=0;i { if(inputs[i].type == "checkbox") { if(inputs[i].id == chk.id) inputs[i].checked = true; else inputs[i].checked = false; } } } And to your checkbox in datalist add this onclick = "CheckBoxClicked(this)" runat="server" Text="" />
