ElencySolutions.MultipleProperty v1.6 Released

A new version of my multiple property assembly is now available.

New Features

You are now able to add custom validation to singular or collection based entity properties.

Making use of the new validation functionality

Two new virtual methods have been added to the MultiplePropertyBase class.  These methods are named ValidateEntity and ValidateEntities.  Example validation code is below:

public class PropertyGalleryImages : MultiplePropertyBase<GalleryImages, GalleryImage>
{
     public override string ValidateEntity(GalleryImage entity)
     {
         if (entity == null)
             return string.Empty;
         if (!entity.LinkUrl.StartsWith("http"))
            return "A link URL must start with http";
     }
 }

public class PropertyGalleryImages : MultiplePropertyBase<GalleryImages, GalleryImage>
{
     public override string ValidateEntities(GalleryImages entities)
     {
         if (entities == null)
             return string.Empty;
         StringBuilder errorMessage = new StringBuilder();
         for (int i = 0; i < entities.Count; i++)
         {
            GalleryImage galleryImage = entities[i];
            if (!galleryImage.LinkUrl.StartsWith("http"))
               errorMessage.AppendFormat("Item {0} link url is invalid, ", i + 1);
         }
		  
         return errorMessage.ToString().TrimEnd(“, “);
      }
 }

Installation

The easiest way to install the assembly is by installing it from the EPiServer nuget feed (once it has been made available).  But if you are not down with the cool kids you can download it from codeplex.  The assembly is built for EPiServer CMS 6 and onwards.

On the codeplex site you can also find some useful documentation and example code to get you familiar with what the property offers.  The example code is dependent on PageTypeBuilder.

Feedback

As always feedback is greatly appreciated, if you have any suggestions for new features or changes I am happy to hear them.
