Update a listbox when Radwidow closes

[Eric Klein]

I am trying to update a list box on the parent when a radwindow closes.  The listbox is populated from a database in code behind.  Actuallly happens on a dropdown_selected index change event.  Just want to load the listobx with the new data when the user closes the radwindow.

One more think I have an update panel and when I tried to ues a RadAjaxManager they clashed.

Hello Eric,

One approach would be attaching OnClientClose event to window, and in the event handler invoke an ajaxRequest(). Then from the server side RadAjaxManager1_AjaxRequest event, refresh the RadListBox.

JavaScript:

<script type="text/javascript">

function OnClientClose()

{

$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest();

}

</script>

C#:

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

// Set the DataSource and DataBind() RadListBox

}

Also set the AjaxSetting as shown below.

ASPX:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadListBox1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

Hope this helps,

Shinu.

I have tried this but the Update panel and the RadAjax Manager clash.  I get this when it runs the on client close.
