[Solved] Arguments are null when OnClientSelectedIndexChanged is raised

[Pooya]

I used the codes written here for OnClientSelectedIndexChanged: http://www.telerik.com/help/aspnet-ajax/combo_clientsideonclientselectedindexchanged.html

The event is raised when an item selection is changed but the parameters are not passed.

eventArgs is null inside the function and sender just has Text and Value properties.

Any help is much appreciated.

Hello,

I tried the same code and it is working fine in my end. Have a look at the code that I tried (with ASP.NET AJAX version 2009.01.0311.35).

ASPX:

<telerik:RadComboBox ID="RadComboBox2" runat="server" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged">
    <Items>
        <telerik:RadComboBoxItem Text="Item1" />
        <telerik:RadComboBoxItem Text="Item2" />
    </Items>
</telerik:RadComboBox>

JavaScript:

<script type="text/javascript">
function OnClientSelectedIndexChanged(sender, eventArgs)
{
 var item = eventArgs.get_item();
 sender.set_text("You selected " + item.get_text());
}
</script>

I guess you are using ASP.NET version of RadControl (not the AJAX version). In ASP.NET version "OnClientSelectedIndexChanged" receives only single parameter which is the newly selected item. If you are using ASP.NET version of RadControls, then follow the documentation below.
OnClientSelectedIndexChanged

Thanks mate.

I think you're right; my assembly name is RadComboBox.Net2.dll which should be the asp.net version.

In which assembly is the ASP.NET AJAX ComboBox?

Thanks.
