Hi,

I'm very new to razor and struggling with something.

I have a partial view which outputs related links in the left nav, I'm trying to do the same thing with related media e.g. pdf's that I've selected with the multiple media picker. This is the code for the links list:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

@*
    Related Items / Links / Pages 
*@

@{
    if ( Model.Content.HasValue("relatedItems") )
    {
        if ( CurrentPage.relatedItems.Count > 0 )
        {
            <div class="related-items">
                <div class="page-header">
                    <h2>@umbraco.library.GetDictionaryItem("Related")</h2>
                </div>
                <ul class="nav nav-list">
                    @foreach(var link in CurrentPage.relatedItems)
                    {
                        <li>
                            @{
                                var linkTarget = link.newwindow == "1" ? "target=\"_blank\"" : "";
                            }
                            <a href="@link.link" @Html.Raw(linkTarget)>@link.title</a>
                        </li>
                    }
                </ul>
            </div>
        } 

    }
}

Can anybody help with this and also suggest where I can find some good reference material to learn Razor? Not having intellisense and syntax checking in the back office is a real pain :(

Thanks

Rich

Hi Rich,

If you install Jeavon Leopold's Umbraco Core Property Value Converters package and follow his documentation, you'll be able to write something like the following:
```
@{
    var media = Model.Content.GetPropertyValue<IEnumerable<IPublishedContent>>("relatedItems");
    if (media.Any())
    {
        foreach (var item in media)
        {
            <a href="@item.Url" target="_blank">@item.Name</a>
        }
    }
}
```
Thanks, Dan.

Hi Rich,

While of course I would agree with Dan that my package makes this super simple you can also do it without and there is a code snippet in the documention here

Also if you want intellisence you can used the typed model (Model.Content) and Visual Studio Express or WebMatrix to edit your Views/Partials/Etc

Thank you Dan and Jeavon.

I have re worked the code as per the example but it doesn't appear to be rendering?

 @if (Model.Content.HasValue("relatedMedias"))
{
        if ( CurrentPage.relatedMedias.Count > 0 )
       {
           <div class="related-links">
                <div class="page-header">
                   <h2>@umbraco.library.GetDictionaryItem("RelatedMedia")</h2>
               </div>
               <ul class="nav nav-list">
         @{
            var relatedMediasList = Model.Content.GetPropertyValue<string>("relatedMedias").Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries).Select(int.Parse);
            var relatedMediasCollection = Umbraco.TypedMedia(relatedMediasList).Where(x => x != null);
       }
                       @foreach (var relatedMedia in relatedMediasCollection)
                       {
                       <li>
                           <img src="@relatedMedia.Url" style="width:300px;height:300px" />
                       </li>
                       }
                   </ul>
   </div>
   }
       }

Hi Richard,

Please try,

 @if (Model.Content.HasValue("relatedMedias"))
{             
            var relatedMediasList = Model.Content.GetPropertyValue<string>("relatedMedias").Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries).Select(int.Parse);
            var relatedMediasCollection = Umbraco.TypedMedia(relatedMediasList).Where(x => x != null);

        if ( relatedMediasCollection.Any() )
       {
           <div class="related-links">
                <div class="page-header">
                   <h2>@Umbraco.GetDictionaryValue("RelatedMedia")</h2>
               </div>
               <ul class="nav nav-list">
                       @foreach (var relatedMedia in relatedMediasCollection)
                       {
                       <li>
                           <img src="@relatedMedia.Url" style="width:300px;height:300px" />
                       </li>
                       }
                   </ul>
   </div>
   }
       }
