<p>Hi,</p> <p>You could do something like this (untested code):</p> <pre class="brush:html;auto-links:false;toolbar:false" contenteditable="false">var repo = ServiceLocator.Current.GetInstance&lt;IContentRepository&gt;(); var assetHelper = ServiceLocator.Current.GetInstance&lt;ContentAssetHelper&gt;(); var newPage = repo.GetDefault&lt;YourPageType&gt;(ContentReference.StartPage); repo.Save(newPage, SaveAction.Save, AccessLevel.NoAccess); var assetFolder = assetHelper.GetOrCreateAssetFolder(newPage.ContentLink); var slideItem = repo.GetDefault&lt;SlideshowItem&gt;(assetFolder.ContentLink); repo.Save((IContent)slideItem, SaveAction.Publish, AccessLevel.NoAccess); newPage.Slideshow.Items.Add(new ContentAreaItem { ContentLink = ((IContent)slideItem).ContentLink }); repo.Save(newPage, SaveAction.Publish | SaveAction.ForceCurrentVersion, AccessLevel.NoAccess);</pre> <p></p> <p>This code will create a new instance of SlideshowItem, store it in the page's asset folder, then add it to the content area and finally publish the page.</p> <p></p> <p></p>

<p></p> <p>Oh, and you need to add the image to the slideItem of course. You can't add the image reference directly to the content area. Unless you wanna skip the whole SlideshowItem block, and just add images directly to the content area.</p> <p></p>

<p></p> <p>Btw, this has nothing to do with local blocks (aka blocks as properties). If you change the property type of the Slideshow property from ContentArea to SlideshowItem, then you would have a local block.</p> <p></p>

<p>Thanks Johan! I follow and it seems like it should do it... Just tested it and ran into a white error page when posting the form but I should look into the whole thing a bit more when I have time. How would you go about adding the image straight to the contentarea (Slideshow - skipping the actual SlideshowItem block). Don't&nbsp;you have to assign the image to the slideItem property (slideItem.Image)? Feel a bit confused over the whole block thing in this case.</p>

<p>You might have to remove "| SaveAction.ForceCurrentVersion" on the last row. ForceCurrentVersion only works if you already have a plublished version, I think...</p> <p></p> <p>You can add anything that implements IContent, i.e. has a ContentReference, to a content area. Out of the box you have pages, blocks, media and content folders.</p> <pre class="brush:html;auto-links:false;toolbar:false" contenteditable="false">newPage.Slideshow.Items.Add(new ContentAreaItem { ContentLink = yourImage.ContentLink }); // instead of newPage.Slideshow.Items.Add(new ContentAreaItem { ContentLink = ((IContent)slideItem).ContentLink }); </pre> <p></p> <p>In your case you might want to have more information on every slide in your slideshow, and not just the image? Then it makes sense to have a block with more properties, e.g. a link and text property.</p> <p></p>

<p>Okey, that seems like a good and quite simple thing to do&nbsp;:) I still feel a bit confused about how I should reference the image (being uploaded with the form). Here's part of the code being used for&nbsp;handling the image being uploaded:</p> <pre class="brush:csharp;auto-links:false;toolbar:false;first-line:0" contenteditable="false">var file = Request.Files[0]; var contentRepository = ServiceLocator.Current.GetInstance&lt;IContentRepository&gt;(); var mediaObject = contentRepository.GetDefault&lt;ImageFileData&gt;(GetParent()); mediaObject.Name = DateTime.Now.ToString("yyyy-MM-dd_HHmm") + Path.GetExtension(file.FileName); mediaObject.Description = newPage.Name; var blob = ServiceLocator.Current.GetInstance&lt;BlobFactory&gt;().CreateBlob(mediaObject.BinaryDataContainer, Path.GetExtension(file.FileName)); blob.Write(file.InputStream); mediaObject.BinaryData = blob; newPage.TeaserImage = contentRepository.Save(mediaObject, SaveAction.Publish, EPiServer.Security.AccessLevel.NoAccess);</pre> <pre class="brush:html;auto-links:false;toolbar:false" contenteditable="false">... repo.Save(newPage, EPiServer.DataAccess.SaveAction.Save, EPiServer.Security.AccessLevel.NoAccess);</pre> <p></p> <p>TeaserImage is a regular property for an image file and this part works like a charm. The new page is being created and the uploaded image is added to TeaserImage. I can't seem to get the reference "yourImage"/"theImage" part right (see below) in your suggestion. Been trying all kinds of different references (that kind of makes sense) to the file without any success. Ex:</p> <pre class="brush:csharp;auto-links:false;toolbar:false" contenteditable="false"> var theImage = Locate.ContentRepository().Get&lt;IContent&gt;(newPage.TeaserImage) as ImageData; newPage.Slideshow.Items.Add(new ContentAreaItem { ContentLink = theImage.ContentLink });</pre> <p></p> <p></p> <p>The project builds but I still get a white internal error page when submitting the form. Any idea what I could be doing wrong?</p> <p></p>

<p></p> <p>Your code looks fine. But you don't need to re-fetch the image if you already have the reference:</p> <pre class="brush:html;auto-links:false;toolbar:false" contenteditable="false">newPage.Slideshow.Items.Add(new ContentAreaItem { ContentLink = newPage.TeaserImage }); </pre> <p></p> <p>I think you need to debug to see where the code fails. Then you could post the stacktrace here.</p> <p></p>

<p>Thanks but I've tried that as well... I get the same exception no matter which one I use. I've also tried to put it later in the code. The new page is then being saved at first but I get the same error/exception trying to save the page again:</p> <div class="line number1 index0 alt2"> <pre class="brush:csharp;auto-links:false;toolbar:false" contenteditable="false">var theImage = Locate.ContentRepository().Get&lt;IContent&gt;(newPage.TeaserImage) as ImageFileData; newPage.Slideshow.Items.Add(new ContentAreaItem { ContentLink = theImage.ContentLink }); repo.Save(newPage, EPiServer.DataAccess.SaveAction.Save, EPiServer.Security.AccessLevel.NoAccess);</pre> </div> <p>Looking at the event&nbsp;viewer&nbsp;I find this warning (telling me there's something wrong with the reference on the specific line):</p> <p>Exception information: <br /> Exception type: NullReferenceException <br /> Exception message: Object reference not set to an instance of an object.</p> <p>If I remove the&nbsp;part (trying to add the image to the contentarea) it works just fine. The contentarea accepts slidshow blocks and ImageFileData (a mediatype). A bit frustrating I must say :)</p> <p></p>

<p></p> <p>Is there a reason why you can't debug the code? Looking in the event log is not the best method of finding exceptions in the code.</p> <p>If you're getting a null reference on theImage.ContentLink, it means that the image doesn't exist, or it isn't an ImageFileData.&nbsp;</p> <p></p>

<p>Yes, kind of... I think. Every attemp trying to debug in VS&nbsp;I&nbsp;don't see any variables or their values. I'm in debug mode running the site but maybe I'm doing something wrong debugging? Shouldn't there be any output in VS while I'm surfing the site?</p>
