Greetings,

I have a radgrid with an image on each lines which opens a radwindow. When i close My radwindow i need to refresh the grid which is in the parent page.


This is how i close my radwindow:

                    
    <asp:Button ID="Validation" runat="server" Text="Enregistrer et envoyer l'offre" OnClick="Validation_Click"
OnClientClick="if(Page_ClientValidate()) CloseDialog()" UseSubmitBehavior="false"
 />
    
function GetRadWindow() {
    var oWindow = null;
    if (window.radWindow) oWindow = window.radWindow;
    else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
    return oWindow;
}
 
function CloseDialog() {
    GetRadWindow().close();
    return true;
 
 
}


I tried to do it that way in my parent page:

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="true">
    <Windows>
        <telerik:RadWindow ID="RadWindow1" runat="server" Width="700px" Height="500px" Title="Details du ticket"
            Skin="WebBlue" Behaviors="Close, Move" Modal="true" OnClientClose="closeRadWindow">
        </telerik:RadWindow>
    </Windows>
</telerik:RadWindowManager>
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadGrid1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>
JS:

<script type="text/javascript"
function closeRadWindow() 
    $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest();  
</script>
.CS

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
    RadGrid1.MasterTableView.SortExpressions.Clear();
    RadGrid1.MasterTableView.GroupByExpressions.Clear();
    RadGrid1.Rebind();
}


It doesn't work. Is there anything i'm missing

(got a JS error with IE ( Property id null or undefined ), & no error but not working at all with firefox)

thanks in advance

Hi Ronan,

This is working correctly with me: http://screencast.com/t/3iXbQ8opu. You can find here my sample page as well so you can compare it with yours and try to locate the difference that is causing this behavior. What I can suggest is that you review if any other script is throwing an error which will prevent AJAX from working. You can also try calling the ajaxRequest() method with a small timeout. i.e.:
setTimeout(function ()
{
    $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest();
}, 100);

If this works you can reduce the timeout, even 0ms could suffice.

Kind regards,
Marin
