var strBranch = document.getElementById('hidBranchLst').value
var strBranchList = strBranch.split('|');
var MulSel = document.getElementById('ddlBranch');
MulSel.multiple = true;
for (var j = 0; j < strBranchList.length; j++) {
alert(strBranchList[j].toString());
for (var i = MulSel.options.length - 1; i >= 0; i--) {
if (MulSel.options[i].value == strBranchList[j].toString()) {
MulSel.selectedIndex = i;
}
}
