I have a solution with a custom Document Set content type declaration. I'm also using solution event receiver to define formurls for my CT:
SPContentType ct = web.ContentTypes["MyDocSetCT"]; ct.NewFormUrl = "_layouts/15/RMFields/newdocsetMyDocSet.aspx"; ct.DisplayFormUrl = "_layouts/15/RMFields/DispFormMyDocSet.aspx"; ct.Update(true);
Is it possible to define Document Set welcome page in a same way? I'm using Sharepoint server 2013, if it's matter.
