Using Javascript we can do ......
function AddItemsToListBox(FromList,ToList,HdnField,HdnIDs)
{
// frm=document.forms[0]
var j=0;
for(i=0;i<FromList.length;i++)
{
if(FromList.options[i].selected)
{
var OptionExistanceCheck;
var opt = document.createElement("option");
newOpt=FromList.options[i].text;
newIDOpt=FromList.options[i].value;
for (k=0; k<ToList.options.length; k++)
{
if (newOpt == ToList.options[k].text)
{
OptionExistanceCheck=true;
}
}
// a=field2.length
// alert(a)
// field2.length++
// alert(ToList.length)
a=ToList.length
if(!OptionExistanceCheck)
{
ToList.options[a]= new Option(newOpt,newIDOpt);
HdnField.value +="~" + newOpt;
HdnIDs.value +="~" + newIDOpt;
}
j++
}
}
}
