    I'm trying to use the MVC ViewBag to set an items text dynamically.  However I get error messages when I do the following:

    items.Add().Text(ViewBag.AppContext.UserDisplayName)

    However, if I do something like the below, it works.  So I think it has to do with the ViewBag not being available (timing).

    items.Add().Text(User.Identity.Name)

    Here's the error when I try and use ViewBag data - CS1977: Cannot use a lambda expression as an argument to a dynamically dispatched operation without first casting it to a delegate or expression tree type.

    Thoughts?

    I figured a way around it, declare a variable before you create the menu and use the variable instead of the ViewBag when setting the menu text like so:

    @{
        string displayName = ViewBag.AppContext.UserDisplayName;
     
        @(Html.Kendo().Menu()
              .Name("userMenu")
              .OpenOnClick(true)
              .Items(items =>
              {
                  items.Add().Text(displayName)

    I know this is an old topic. Just in case someone else come across this topic.
     
    There is no need to declare a separate variable at least on the latest version of Kendo.

    Do cast "UserDisplayName" to string as follows:

    items.Add().Text( (String) ViewBag.AppContext.UserDisplayName )
