    When I write the code to update the tooltip in my vb code I get the error:
        - Cannot convert type system.web.ui.control to content.

    Content is my web usercontrol. Here is my code


    Sub UpdateToolTip(ByVal elementID As String, ByVal panel As UpdatePanel)
    Dim ctrl As UserControl = Page.LoadControl("~/secured/admin/Content.ascx")   panel.ContentTemplateContainer.Controls.Add(ctrl)
    Dim content As Content = DirectCast(ctrl, Content)
    content.ContentID = elementID
    End Sub

    The error is on the ctrl element. I have copied the code from the demo, so it should work. I don't understand what's wrong.

    Hello Jean-Philippe,
    Please make sure that you have the following line in your aspx:
    <%@ Register Src="Content.ascx" TagName="Content" TagPrefix="uc1" %> 

    In case this does not solve the problem, please open a new support ticket and send us a simple running project, demonstrating it.

    Kind regards,
