Hello,

I am new to Umbraco/Razor (and to .net development also please bear with me for a moment), the following code is a razor macro.

@using System.Diagnostics
@using umbraco.MacroEngines
@inherits DynamicNodeContext

@{
    String thisis = "";
    DynamicNode video = null;
    DynamicNodeList listOfVideos = null;
    if (@Model.NodeTypeAlias == "VideoFAQ")
    {
        thisis = "one particular video";
        video = @Model;
        listOfVideos = @Model.Ancestors("VideoFAQPage").Items[0].Children.Where("NodeTypeAlias == \"VideoFAQ\"");
    }
    else if (@Model.NodeTypeAlias == "VideoFAQPage")
    {
        thisis = "A Page containing lot of videos.";
        video = @Model.VideoFAQ.Items[0];
        listOfVideos = @Model.VideoFAQ;
    }
}

When I try to do this

@video.HtmlMarkup

HtmlMarkup is a property defined on the Document Type , the same works if I do it the @Model.HtmlMarkup way.

There comes an error, My guess is that it is because the way I am constructing this.

can someon please tell me what is going on.... and if there is a better way to do it.

I am still getting the error.

Error loading MacroEngine script (file: ~/macroscripts/videofaq/anothertest.cshtml)

The code is now.

@using System.Diagnostics
@using umbraco.MacroEngines
@inherits umbraco.MacroEngines.DynamicNodeContext
@{
    String thisis = "";
    DynamicNode video = null;
    DynamicNodeList listOfVideos = null;
    if (@Model.NodeTypeAlias == "VideoFAQ")
    {
        thisis = "one particular video";
        video = @Model;
        listOfVideos = @Model.Ancestors("VideoFAQPage").Items[0].Children.Where("NodeTypeAlias == \"VideoFAQ\"");
    }
    else if (@Model.NodeTypeAlias == "VideoFAQPage")
    {
        thisis = "A Page containing lot of videos.";
        video = @Model.VideoFAQ.Items[0];
        listOfVideos = @Model.VideoFAQ;
    }
    @video.HtmlMarkup
}

I don't know if it matters a lot, but I am loading the macro (as i saw in the Cultiv Razor examples...by using the filelocation attribute of the Umbraco:macro tag)

Hi Arun,

Can you try removing the @ symbol within the if statment so as
```
if(Model.NodeTypeAlias = "VideoFAQ"){
thisis = "one particular video"; 
}

@(Html.Raw(@thisis));
@Model.HtmlMarkup
```

Hi Fuji,

I tried that and it is not working.

I think it has to do something about the way these assigments are taking place, I am very new to .net development, but as far as I know (and I hope I am right)... while creating @Model umbraco does something to the DynamicNode (like add some methods and properties to the runtime object) and when In the code I am trying to reassign these to other variables (which are basically DN and DNL), these magic things are not coming to me, it seems that they are being assigned by a copy and not by reference. Some syntatic sugar goes missing...

The reason I say so is because the following seems to be working fine.
```
@Html.Raw(@video.GetPropertyValue("htmlMarkup")); 
```
And the following Won't work
```
@Html.Raw(@video.HtmlMarkup) 
```
I am also getting a Red Squiggly line with the following error message in visual studio
```
umbraco.MacroEngines.DynamicNode does not contain a definition for HtmlMarkup and no extension method 'HtmlMarkup' accepting a first arguement of type 'umbraco.MacroEngines.DynamicNode' could be found (are you missing a using directive or an assembly reference) 
```
Cheers,
Arun
