    Retrieve media items for current id

    Hi There, I'm looping through a list of child pages and passing the page id into a partial. From the partial i'd like to loop through all of the media items (in this case pdf files) that are attached to that particular page. How can I do this in razor?

    Thanks in advance.

     foreach (var pageCodeSnippets in Model.Content.Children())

                    {

                        count++;

                        <h3>@pageCodeSnippets.GetProperty("snippetTitle").Value</h3>

                        <p>@pageCodeSnippets.GetProperty("snippetParagraph").Value</p>

                        <section class="section row">

                            <div id="snippet-@count">@Html.Raw(pageCodeSnippets.GetProperty("snippetbody").Value)</div>

                        </section>                                                                                                                                                                   

                       @RenderPage("~/Views/Partials/_PDFThumbnailsView.cshtml", @pageCodeSnippets.Id)

     

                    }

    !-- partial

     var mediaFolder = "<Not Sure How To Do This>"

     

     

     

    if (mediaFolder.Children.Any())

        {

            <ul>

                @* for each item in children of the selected media folder *@

     

     

     

                @foreach (var mediaItem in mediaFolder.Children)

                {

     

     

     

                    int mediaID = mediaItem.Id;

                    var pdf = PDFHelper.GetMedia(mediaID);

                    <li>

                        <h5><a href="@mediaItem.umbracoFile">@mediaItem.Name</a></h5>

     

     

                         @*@foreach (var thumb in pdf.PdfThumbs)

                            {

                                <a target="_blank" href="@pdf.Media.Url"><img height="200" src="@thumb.fileName" [email protected]""></a>

                            }*@

     

                    </li>

                }

            </ul>

        }

     

    } else {

        <p>is null</p>

     

    }

    Hi Sean,

    I think that you can get the images from the are attached to that particular page, by doing something like this. From you code that you have posted in your post I assume that you´re using strongly typed razor.

    @{ 
        foreach (var pageCodeSnippets in Model.Content.Children()){
           
            count++;

            <h3>@pageCodeSnippets.GetProperty("snippetTitle").Value</h3>

            <p>@pageCodeSnippets.GetProperty("snippetParagraph").Value</p>

            <section class="section row">

                <div id="snippet-@count">@Html.Raw(pageCodeSnippets.GetProperty("snippetbody").Value)</div>

            </section>                                                                                                                                                              
       
            @if(pageCodeSnippets.HasValue("propertyAlias")){                  
                
                var media = Umbraco.TypedMedia(pageCodeSnippets.GetPropertyValue("propertyAlias"));
               

                foreach(var photo in media.Children)
                {
                    <li>
                        <img src="@photo.GetPropertyValue("umbracoFile")" alt="@photo.GetPropertyValue("Name")"/>   
                    </li>              
                }
                } else{
                    <p>Is null</p>
            }
        }
    }

    Remember to change propertyAlias so it fetch your alias of your property where the user should choose the folder with the images.

    Possibly take a look here: http://our.umbraco.org/forum/umbraco-7/using-umbraco-7/54157-Rendering-Macro-inside-Partial-View

    Hope this helps, or can be a good starting point at least,

    /Dennis

    HI Dennis,

    Thanks for the Answer much appreciated. I ended up with the following which seems to work locally anyway.  Now I have to find out why it does not work on windows Azure.

     

         @* Check the document type *@

                @if (Model.Content.DocumentTypeAlias == "CodeContentDocumentType")

                {

     

                    int count = 0;

                    @* Get a list of properties from the current node *@

                    foreach (var pageCodeSnippets in Model.Content.Children())

                    {

                        count++;

     

                        <h3>@pageCodeSnippets.GetProperty("snippetTitle").Valueh3>

     

                        @* check that the article has files to go with it*@

                        if (pageCodeSnippets.HasValue("articleFiles"))

                        {

                            foreach (var mediaItem in @pageCodeSnippets.GetProperty("articleFiles").Value.ToString().Split(','))

                            {

                                int mediaID = int.Parse(mediaItem);

                                var pdf = PDFHelper.GetMedia(mediaID);

                                var mediaFiles = ApplicationContext.Current.Services.MediaService.GetById(mediaID);

                                var theCurrentFileName = String.Empty;

                                var theLastFileName = String.Empty;

                                @* loop through the list of thumbs only showing the first one*@

     

     

                                foreach (var thumb in pdf.PdfThumbs)

                                {

                                    if (!String.IsNullOrEmpty(thumb.fileName))

                                    {

                                        theCurrentFileName = mediaFiles.Name;

     

                                        if (theCurrentFileName != theLastFileName)

                                        {

                                            <div class="row">
