I am using telerik.web.ui v2011.3.1305.35. When you set the checked property for a radCombobox to "true", each item you check creates a concatenated, comma separated list in the display box. This uses the item text of the combo box. How can you do the same thing except display the item "value" in a comma separated list? BTW, this is way cool and made life a lot easier coding wise.

Hi Dennis,

In order to achieve the desired functionality, you could use the OnClientItemChecked event in the following manner :
<script type="text/javascript">
 
     function OnClientItemChecked(sender, eventArgs) {
 
         var stringValues = "";
         var firstTime = "true";
         var itemsLenght = sender.get_checkedItems().length;
 
         for (i = 0; i < itemsLenght; i++) {
 
             if (firstTime != "true") {
                 stringValues += ",";
             }
 
             firstTime = "false";
 
             stringValues += sender.get_items().getItem(i).get_value();
         }
         
         setTimeout(function () { sender.set_text(stringValues) }, 1);
     }
 
 </script>



All the best,
