Bulk InsertItems into Listbox

[Dan]

I am trying to do a bulk insert items from one radlistbox to another radlistbox.  In my javascript code, I am getting all the checkeditems from the first listbox (which returns an array) and trying to insert them into the destination (provision) listbox.

 function SetProvisions(RadListBoxArray) {

         var RadListBoxCount = RadListBoxArray.length;
         var i = 0;
         var ProvisionListBox = $find("<%= uxProvisions.ClientID %>");

         for (i = 0; i < RadListBoxCount; i++) {
             var RadListBox = RadListBoxArray[i];
             var RadListBoxCheckedItems = RadListBox.get_checkedItems();
             ProvisionListBox.insertItems(RadListBoxCheckedItems);       <<<<Getting error here
         }

         ProvisionListBox.commitChanges();
     }

Getting error stating that "Array of RadListBox items or Telerik.Web.UI.RadListBoxItem collection should be passed."

Hello dan,

From the error I assume that "RadListBoxCheckedItems"  is not a collection of RadListItems. Could you check whether it retrieves RadListBoxItems collection?

The "insertItems" method worked perfectly in my end when I passed RadListBoxItems array as parameter.
 

Thanks,
Princy.
