$fin() always returns null with radwindow

[Kareem]

Hello I'm trying to open a radwindow from the server side on the event on some a linked button on a radgrid clicked it makes an ajax call using the ajax manager

the problem is the $find() function always returns null

 I tried every possible solution I found online and the javascript function is at the end of the page

<telerik:RadCodeBlock ID="CodeCodeCode" runat="server">
        <script type="text/javascript">
            function OpenWindow(url)
            {
                var rwindow = $find("<%= rw_customerfeedback.ClientID %>");
                rwindow.setUrl(url);
                rwindow.show(url);
                rwindow.center();
            }
        </script>
 </telerik:RadCodeBlock>

here's how I make the ajax call

<telerik:AjaxSetting AjaxControlID="lnkbtn_complaint">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="rw_customerfeedback" />
                    </UpdatedControls>
</telerik:AjaxSetting>

and here's how I call the java script code

string corporateIdentifier = RouteData.Values["CorporateIdentitfier"].ToString();
           string url = Page.GetRouteUrl("Complaints", new RouteValueDictionary{{"CorporateIdentifier", corporateIdentifier }});
           string script = @"OpenWindow('" + url + "');";
           Session["TicketID"] = e.CommandArgument;
           ScriptManager.RegisterStartupScript(this, this.GetType(), "OpenWindow", script, true);

Hello,

I advise that you review the following articles:

• on how to open a RadWindow from the server: http://docs.telerik.com/devtools/aspnet-ajax/controls/window/troubleshooting/opening-from-the-server. In a similar fashion you can call your own function.
• on using RadWindow with AJAX: http://docs.telerik.com/devtools/aspnet-ajax/controls/window/how-to/how-to-use-radwindow-with-ajax. Usually, it is best to keep the RadWindow out of the response and manipulate it with JS.
• on registering script calls from the server: http://docs.telerik.com/devtools/aspnet-ajax/controls/window/troubleshooting/executing-javascript-code-from-server. Note how the Sys.Application.Load event should be used when working with IScriptControls like ours. This applies when they are part of the response, of course.

Dear Marin Bratanov,

you have to understand that I've already tried all the solution mentioned in those articles

more over I have no problem launching the script from the server the script launches just fine

the problem is that the $find always returns null when I try to search for the radwindow

there's something I forgot to mention I set all the controls client IDs to static, is that might be causing the problem??

Hello,

ClientIDMode = Static is not supported by our controls and you should remove this property: http://docs.telerik.com/devtools/aspnet-ajax/general-information/troubleshooting/general-troubleshooting#setting-clientidmode-property-to-static-breaks-the-telerik-controls-functionality.
