    Struggling with Html.Raw - Macro Outputting Html Encoded value

    Razor

    I have a macro in which i'm building up a message from a few parameters on a node.  However when i output it (using the variable that i built up containing all the HTML), it renders the encoded value, IE: I see the HTML on the page, not the rendered HTML.

    Here's my code (a snippet of it anyway):

    @if (showMessage)
    

    {
    

        //@(Html.Raw(message.ToString()));
    

        @message;
    

    }
    

     
    

    @functions{
    ...
       protected override void InitializePage()
        {
    ...
            var requestedUrl = Request.Url.PathAndQuery.ToString(); // default get back to same page after valid login;
            if (isLoggedIn)
    

            {
    

                if (!isSubmitLogout)
    

                {
    

                    message = String.Format("<div class=\"header\">{0}</div>", @Model.signedInConfirmationHeader);
    

                    message = String.Concat(message, String.Format("<p>{0}</p>", @Model.signedInConfirmationMessage)); //Html.Raw(@Model.signedInConfirmationMessage)
    

                    message = message.Replace("%USER%", currentUser.UserName);
    

                    try
    

                    {
    

                        message = Html.Raw(message);
    

                    }
    

                    catch (Exception ex)
    

                    {
    

                        message = String.Format("ERROR: {0}", ex.Message);
    

                    }
    

                    showMessage = true;

     

    So in the above code, it errors. It doesn't even handle the exception and show the message, i just get a message saying there was an error with the script.

    If i remove the Html.Raw(..) block, it'll work but not render the HTML.

    I'm pretty stumped with this.. any ideas??

    I've also tried every combination i can think of of @Html.Raw(message) etc in the top section where it actually outputs the value. All just throws a generic error.

    Also i've tried changing the "signedInConfirmationMessage" property to a Textbox Multiple - same behaviour.

    HTML i'm passing to Html.Raw() is valid - I've checked that.
    UGH!!

    Maybe try setting it up like this. 

      @{
        var showMessage = true;
        var message = "<div>Test Message</div>";
        if (showMessage) {
          @Html.Raw(message)
        }
      }

     

    Did you try placing the function before the output?

     

    Sorry I can't be much more help.

    Thanks Dan... not a bad idea to isolate it, makes it a bit clearer where the issue is:

    This throws an error:

    @if (showMessage)

    {

        //@(Html.Raw(message.ToString()));

        //@message;

     

        var message2 = "<div>Test Message</div>";

        @Html.Raw(message2);

        //@message2;

    }

     

    But this outputs the html encoded text to screen (ie: shows the markup on the front end):

    @if (showMessage)

    {

        //@(Html.Raw(message.ToString()));

        //@message;

     

        var message2 = "<div>Test Message</div>";

        //Html.Raw(message2);

        @message2;

    }

     

    So i think we can rule out the use of the function, or the placement of it, from this issue.  The issue is with building up a varialble containing HTML text, and then outputting it to the screen using Html.Raw().  

    Anyone??

        //(Html.Raw(message.ToString()));   <<<<<<<<<<<<<< THIS BIT!!!  you have a ( around the front of HTML.Raw //this will not help :)

        //message;

     

        var message2 = "<div>Test Message</div>";

        @Html.Raw(message2);

        //@message2;

    }

     

    also i think you should use @{    } around you code and not  @ @ @ on every line :).  Charlie

    Turns out the issue was with is in 4.9.0, only with MVC Macros.  Switching to a User Control macro solved the issue on this version.

    For me this worked:

    @inherits Umbraco.Web.Macros.PartialViewMacroPage

@{
    var myString = Model.MacroParameters["param_alias"].ToString();
}

@Html.Raw(HttpUtility.HtmlDecode(myString))

    -cheers
