EPiServer 7 relies on dojo for renderinge the form. This is a major change from how it worked in previous CMS versions. From having built lots of custom properties in my days I haven't done any in CMS 7 yet.
You can get more information here in Linus blog post on the topic: http://world.episerver.com/Blogs/Linus-Ekstrom/Dates/2012/7/Creating-a-custom-editor-for-a-property/
Thanks. Off to learning Dojo then I suppose.
I'm developing a new EpiServer 7 site and I'm trying to create a property with a custom editor in the Forms Editing mode. What I basicly want is an ordinary comma seperated string with a list next to it containing a list of previously used tags. I know how to get the datasource, but how do I go about rendering the actual list in the edit view?
I'm thinking something like this: http://joelabrahamsson.com/PageFiles/293/1958_2292.jpg.
