Unfortunately it no longer works for 4.62.Even though it says at Coderesort that it's compatible for version 4 & 5.
After placing the DLL in the bin folder and rebuild the solution, I get the following error:
Failed to load some types from "Intergen.EP.MultiPageProperty": Could not load file or assembly 'EPiServer, Version=5.1.422.4, Culture=neutral, PublicKeyToken=8fe83dea738b45b7' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) Could not load file or assembly 'EPiServer.Web.WebControls, Version=5.1.422.4, Culture=neutral, PublicKeyToken=8fe83dea738b45b7' or one of its dependencies. Systemet finner ikke angitt fil.Is there a working version for 4.x?
Do a SVN checkout of the version 4 trunk: https://www.coderesort.com/svn/epicode/Intergen.EP.MultiPageProperty/trunk/Intergen.EP.MultiPageProperty/, build it, and copy the code into your project (dialog folder, .dll and language files).
