Hi

You need use the JAVA script to this

<script type="text/javascript">

    function SelectAll(id) {

        var frm = document.forms[0];

        for (i=0;i
            if (frm.elements[i].type == "checkbox") {

                if(document.getElementById(id).checked==true)
{
alert(document.getElementById(id).value);

            }

        }

    }

script>

just more details here

hi, i think it helps u function Validations(cnt) { for(i=1;i<=cnt;i++) { if(document.getElementById('datagrid1').rows[i].cells[9].getElementsByTagName("input")[0].checked ==true) { chk=chk+1; break; } } if(chk==0) { alert('Select Atleast One CheckBox'); return false; } } imgbtnSubmit.Attributes.Add("onClick","javascript:return Validations(" + datagrid1.items.count + ")"); place this line of code in page load & after datagrid fill.
