ASCX Control with combo box issue

[dhuss]

I have a custom ascx control that has a radComboBox. This is my code for the combo box and javascript code:

<telerik:RadComboBox ID="radWQStatus" runat="server" AllowCustomText="false" Width="300px"
    DropDownWidth="350px" MaxHeight="300px" NoWrap="true" HighlightTemplatedItems="true"
    ExpandDirection="Down" ExpandDelay="0" CollapseDelay="0" CheckBoxes="true" EnableCheckAllItemsCheckBox="false"
    AutoPostBack="true" OnClientDropDownClosing="OnClientDropDownClosingWQS">
    <Items>
        <telerik:RadComboBoxItem runat="server" Text="Value1" Value="1" />
        <telerik:RadComboBoxItem runat="server" Text="Value2" Value="2" />
        <telerik:RadComboBoxItem runat="server" Text="Value3" Value="3" />
    </Items>
</telerik:RadComboBox>

<script type="text/javascript" language="javascript">
    function OnClientDropDownClosingWQS(sender, args)
        {
            if (args.get_domEvent().target == sender.get_imageDomElement()) {
                args.set_cancel(false);
            }
            else {
                args.set_cancel(true);
            }
        }
</script>

The problem I am having is the combo box keeps closing after each single selection. If I place this same code on a aspx page it works as expected, I can check multiple items before the box closes. What do I have to do to keep the combo box from closing when used in an ascx control place on an aspx page.

Hello Dennis,

I have performed some tests with the provided snippet of code, but I was unable to replicate the experienced issue. Here is a video, demonstrating the behavior of the control at my end.
Am I missing something?

I forgot to mention I have defined a public event in the ASCX control, ItemChecked. When postback occurs this event will fire if the parent page has code created for this event. The only other way I can get this to work the way I want is to not use the event and use a button to fire my code. Sorry for not including this bit of information.
