    I have a user control, DuplicateVinDisplay.ascx, which has a rad grid wtih a linkbutton column. The linkbutton column, when clicked, will call a javascript function that will open a radwindow and display another page. This all was working perfectly when I loaded the user control on page load.

    But, I need to display the user control when the user tabs out of a textbox on the page the user control is hosted on. So, I added the following to my RadAjaxManager on the hosting page:


    <telerik:AjaxSetting AjaxControlID="VINTextBox">
    <telerik:AjaxUpdatedControl ControlID="DuplicateVINDisplay1" LoadingPanelID="defaultRadAjaxLoadingPanel"/>


    This does what I need it to and the user control displays properly when the user tabs our of the VINTextBox control. However, now when I click the linkbutton in the grid, I get a javascript Object Expected error. I have even modified the javascript funtion that is being called to simply be an alert('hi'); but to no avail.

    What might I be missing here?

    Hello Dennis,

    Could you confirm that you are correctly loading the dynamic user control, as described in this help article which elaborates on RadAjax and user controls:
    Load user controls

    Additionally, you should not make a declarative AJAX setting if the control is not always visible on the page. Try adding the setting programmatically in Page_Load or Page_PreRender when you are sure that the user control will be visible on the page.

    Kind regards,
    the Telerik team
