I would kindly ask for your help :) From couple of days I am trying to achieve "linked" custom field in content editor and dropdown in page editor. Basically I want to have dropdown in page editor and content editor which are responsible for a same thing.
In my c# code i have enums which represent directions. I created custom field which accepts assembly and class with overridden onload method and successfully populate dropdown values in the content editor. So far so good but i have no idea how to create dropdown which will represent the same functionality inside page editor. So please give me any ideas...
Judging from your reply to my comment you need to think of the following: How is my field value being rendered onto a page?
If you are always using 1 control to do this then you just need to ensure that this control has 2 different rendering modes depending on the Context.PageMode
But as I understand it you want this dropdown to also appear when someone renders your custom field using a
<sc:FieldRenderer>. In this case you'll need to look into the RenderField pipeline of Sitecore. There you find a processor called RenderWebEditing. Possibly through some manipulation here you can get your dropdown appear as you wish.
