c# – concatenate values to hidden variable

How to concatenate values to the hdnfield value with comma on checkbox click event. when i click the checkbox i select order and passit to the JS function. If i select three checkboxes the hdnfield value should be like 1, 2, 3… something like that… how to do that?


if (chkBoxOne != null) 
{
    chkBoxOne.Attributes.Add(\"onclick\", \"javascript:return SelectOne(\'\" + chkBoxOne.ClientID + \"\',\'\" + e.Row.ClientID + \"\',\'\" + lblorderId.Text + \"\')\");
    //if (chkBoxOne.Checked)
    //    hdSelectAllOrderId.Value += ((Label)e.Row.FindControl(\"lblorderId\")).Text + \",\";
}


function SelectOne(id, rowID, OrderID) {
  var AllOrderIDs = 0;
  AllOrderIDs = Number(document.getElementById(\'ctl00_PagePlaceholder_hdSelectAllOrderId\').value);
  alert(AllOrderIDs);
  if (document.getElementById(id).checked == true) {
      if (AllOrderIDs == \'\')
          AllOrderIDs = OrderID;
      else
          AllOrderIDs = AllOrderIDs + \' ,\' + OrderID;
}
alert(AllOrderIDs);}

The above code is not working. when i click on the firt checkbox its showing frist ordid, but when i click on the second one its not showing first ordid which is i already assigned to it. Its just showing second one…


   var AllOrderIDs = 0;
AllOrderIDs = document.getElementById(\'ctl00_PagePlaceholder_hdSelectAllOrderId\').value;
var IDs = AllOrderIDs.split(\',\');
if (document.getElementById(id).checked == true) {
    if (IDs.indexOf(OrderID) == -1) {
        IDs.push(OrderID);
    }
}
else {
    var index = IDs.indexOf(OrderID);
    if (index != -1) {
        IDs = IDs.slice(index, 1);
    }
}
AllOrderIDs = IDs.join(\',\');
