    Hi there.

    I was just trying to add a simple radalert to my aspx page that I call from my code behind upon successful completion of a task.

    Here is the code I am executing from inside a button click handler:

     

    string scriptstring = "radalert('Task information loaded successfully!', 330, 210);";

     

     

    RadScriptManager.RegisterStartupScript(this, this.GetType(), "radalert", scriptstring, true);

    When I execute the code, I get the following error:

    Error: Object expected

    When looking a the page source, the error is occurring on the first open tag here:

    <script type="text/javascript">
    //<![CDATA[
    radalert('Task information loaded successfully!', 330, 210);Sys.Application.initialize();
    Sys.Application.add_init(function() {
        $create(Telerik.Web.UI.RadAjaxManager, {"_updatePanels":"","ajaxSettings":[],"clientEvents":{OnRequestStart:"",OnResponseEnd:""},"defaultLoadingPanelID":"","enableAJAX":true,"enableHistory":false,"links":[],"styles":[],"uniqueID":"ctl00$RadAjaxManager1","updatePanelsRenderMode":0}, null, null, $get("ctl00_RadAjaxManager1"));
    });
    Sys.Application.add_init(function() {
        $create(Telerik.Web.UI.RadTabStrip, {"_selectedIndex":0,"_skin":"Default","clientStateFieldID":"ctl00_RadTabStrip1_ClientState","selectedIndexes":["0"],"tabData":[{},{},{},{},{}]}, null, null, $get("ctl00_RadTabStrip1"));
    });
    //]]>
    </script>
    </form>
    </body>
    </html>

    I am probably missing something obvious. Any help provided would be much appreciated.

    Mike

    Hello Michael,

    Have you added RadWindowManager on page?
    Also checkout the following KB article which describes how to call RadAlert from code behind.
    Calling radalert from codebehind

    Yep, I was missing the window manager. I thought I had one on the page, but it was on the master page.

    Thanks, Mike
