[sancindy]

Hi ,

I am doin this, but it is not working... I m using IE 7.0
//------------
LeftList = window.opener.document.getElementById("lbResult");
RightList = document.getElementById("DualList_lbRightOption");

alert("1 = " + LeftList); -- showing object
alert("2 = " + RightList);-- showing object

var len = RightList.length -1;
alert("len = " + len);

for(i=len; i>=0; i--)
{
alert("RightList.item(i) = " + RightList.item(i).value);
//LeftList.appendChild(RightList.item(i));
window.opener.document.getElementById("lbResult"). options.add(new Option(RightList.item(i).value,RightList.item(i).v alue));

//window.opener.document.forms["Mainform"].Name_field.value = RightList.options[RightList.selectedIndex].value;
//LeftList.options.value = RightList.options[RightList.selectedIndex].value;

}

//--------------
