How to attach to OnClientItemsRequested in JS?

[Branimir Giurov]

Hi,

I have the following script rendering in my aspx:

Sys.Application.add_load(function () {
    var target = $find('{0}');

    alert(target.get_id());
    //finds it

    $addHandler(target, "OnClientItemsRequested", function (sender, e) { alert('OnClientItemsRequested'); });
    $addHandler(target, "onclientItemsRequested", function (sender, e) { alert('onclientItemsRequested'); });
    $addHandler(target, "clientItemsRequested", function (sender, e) { alert('clientItemsRequested'); });
    $addHandler(target, "clientitemsrequested", function (sender, e) { alert('clientitemsrequested'); });
    $addHandler(target, "onclientitemsrequested", function (sender, e) { alert('onclientitemsrequested'); });

    //none fires
});

The alert showing server id fires, nothing else happens after using the auto-populate, while the same event works when I configure the event-handler in combobox's properties.

My problem is none of the subscriptions works, so is there a way to attach an event-handler function for OnClientItemsRequested in JS?

Thx in advance,

Hi Branimir,

To attach the OnClientItemsRequested client event of the RadComboBox from JavaScript, you must use the add_itemsRequested method as shown in the following sample code.

ASPX:

<telerik:RadComboBox ID="RadComboBox1" runat="server" OnClientLoad="OnClientLoad"
    EnableLoadOnDemand="true">
</telerik:RadComboBox>

JavaScript:

<script type="text/javascript">
    function OnClientLoad(sender, args) {
        sender.add_itemsRequested(OnClientItemsRequested);
    }

    function OnClientItemsRequested(sender, args) {
        //Your Code
    }
</script>

Thanks,
Shinu.
