MVC 5 C# When calling a Html.Action from my controller it doesn't display anything. RRS feed

    I am trying to display all the replies for a ticket on my details page.

    I'm calling my action with this line

    @Html.Action("_RepliesList", "Tickets")

    The ActionResult code is

            public ActionResult _RepliesList()
                IEnumerable<Reply> replies;
                replies = db.Replies.ToList();
                return PartialView("_RepliesList", replies);

    And my Partial view code is

    @model IEnumerable<Example.Reply>
    <table class="table">
                @Html.DisplayNameFor(model => model.Message)
        @foreach (var item in Model)
                    @Html.DisplayFor(modelItem => item.Message)

    But when the page loads, where the replies should be its blank.

    The SQL table has data in it.

    No errors in compiling or loading the page.

    Any thoughts?

    show the definition Example.Reply class.


    @Html.DisplayNameFor(model => model.Message)

    not in foreach ?

    if you put a breakpoint to

    @Html.DisplayFor(modelItem => item.Message)

     "item" contains data?

    Here is the Example.Reply.

    namespace Example
        public partial class Reply
            public int ReplyID { get; set; }
            public string Message { get; set; }

    This is the table header, just grabs the columns name.

    @Html.DisplayNameFor(model => model.Message)

    Hence why it doesn't need to be in foreach.

    Item should be the current index of the list for message.

    If I run this code on a separate page without using a partial view it works.

    "item" contains data in debugger ?

    Or Model in 

    @foreach (var item in Model)

    It just randomly started working? I didn't changed anything except add a login check to another page.

    I personally did not see any errors. Studio bug?

    I think so.

    I don't think you found a bug.  ASP.Net will not directly serve a file that starts with an underscore; it has to be called from another view using Html.Partial, etc.  Did you by chance rename the file to not have an underscore in the name?

    Hi Dmonro,

    I test your code and work fine in my project.

    I can't find anything wrong in your code.

    So I suggest you could add some breakpoints in your _RepliesList action,check if replies has value,

    and open F12 developer tool to check if there are other Javascript code that affect the results of the partial view.

    Best Regards.
