Hi I suppose you are having a ASP checkbox in that column. Please write an onclick javascript function on checkbox as below - onclick=checksel(this.id) /> Now javascript function is as below - function checksel(id) { //Splitting the checkbox ID to find ou row number id1 = id.split('_'); var sameid = ; for (var j = 0; j sameid += id1[j] + _; } //Assigning the unique number in the ID to a variable val = id[id.length - 1]; var totcnt = $('#' + id).parents('tbody')[0].childElementCount - 2; if (document.getElementById(id).checked) { for (var k = 0; k if (!document.getElementById(sameid + k).checked) { alert(You can't select this item before selecting other items!); document.getElementById(id).checked = false; break; } } } else { for (var k = totcnt; k > val; k--) { if (document.getElementById(sameid + k).checked) { alert(You can't unselect this item before unselecting other items!); document.getElementById(id).checked = true; break; } } } } This will prevent selecting / unselecting before preceding ones.
