Catch Event when Clicking over LoadintoProject

[Hans_Dwe]

Hello everyone, 

I would like to ask if it's possible to catch an event when the user clicks over, for example, the LoadintoProject button, for example, I get a popup msg that shows "button clicked"?  I tried to use RevitCommandId but it was unable to show the popup msg. I appreciate any suggestions thanks !!

No official support from the Revit API itself, afaik, but I believe you can achieve this by using the .NET Automation library:

Hello @jeremy_tammik, I meant to be able to see which family has been loaded into the file and save it in an external temp directory, it worked to catch that event(FamilyLoadedIntoDocument) but the problem was I couldn't either save the family while it's being loaded into the Revit file or either to save it after its already loaded into the Revit file, is there a possible way to do it? this is my code so far for more clarification.
