Hi,

Try the following javascript to raise event on clicking Check All checkbox.
JS:
function onLoad(sender) {
$telerik.$('.rcbCheckAllItemsCheckBox').change(function () {
         if (sender.get_text() == "All items checked") {
             alert(sender.get_text() + " some custom action here");
         }
     });
 }

Thanks,
Shinu.

Hi RJ,

Unfortunately I couldn't replicate the issue. Here is the code that I tried based on your scenario which works as expected at my end.

ASPX:
<telerik:RadComboBox ID="RadComboBox1" runat="server" EnableCheckAllItemsCheckBox="true" CheckBoxes="true" OnClientLoad="onLoad" >
  <Items>
        ............
   </Items>
</telerik:RadComboBox>

Another approach is that you can raise the event as follows.

Javascript:
<script type="text/javascript">
$telerik.$(
'.rcbCheckAllItemsCheckBox').change(function () {
               // Your code
            });
</script>

Hi Shinu,
new code wont work, but when I tried the first code again it worked now. My bad, I have localized AllItemsCheckedString thats why it didnt work the first time... Thank you so much.
