Image Data Preview

Vote:
 

Hi All,

I've trying to switch default property preview for a custom one. I followed this article: http://world.episerver.com/documentation/Items/Developers-Guide/EPiServer-CMS/75/Content/Assets-and-media/Custom-editing-preview-for-media/.

For some reason I created a custom view for the preview. Once compiled and run it is not being picked up by the CMS. Instead the default preview is not displaying a preview any more:

I am very quite new to the platform - must be something very lame!

Many thanks,

M

Hi,

Could you show your code? And give more details what would you like to implement?

Hey,

I would like to use it to as a page where the custom image cropping tool will be located.

In terms of the code, I followed the documentation (link in the previous post):

[TemplateDescriptor(Default = true, Tags = new[] { RenderingTags.Preview })]
public partial class ImageFilePreview : PreviewPage, IRenderTemplate<ImageFile>
{

}



Thanks, M

As far as I remember (could be wrong) Media data preview handler is responsible for this. It has following attributes set:

[TemplateDescriptor(AvailableWithoutTag = false, Inherited = true, TagString = "Preview", TemplateTypeCategory = TemplateTypeCategories.HttpHandler)]
public class ImagePreviewHandler : MediaPreviewHandlerBase, IRenderTemplate<IContentImage>, IRenderTemplate
{
}

This is how we've solved it for a generic file in a project. Guess it should work for image as well.

[TemplateDescriptor(
        Inherited = true,
        AvailableWithoutTag = false,
        Tags = new[] { RenderingTags.Edit },
        TemplateTypeCategory = TemplateTypeCategories.MvcController,
        Path = "/Views/GenericMedia/Index.cshtml"
        )]
    public class GenericMediaController : ActionControllerBase, IRenderTemplate<GenericMedia>
    {
        public ActionResult Index(GenericMedia currentBlock)
        {
            return View(currentBlock);
        }
    }
