Eventhandler, when an object-file is updated with another file (UIX)

Question

Hello, 
 I've got an UIX application, which runs when an object is created. It checks a file and returns a message, if the file is not allowed to be saved in M-Files. 
 Now I wan't to imolement the same feature, when a file is updated via Drag&Drop. But I cannot find the correct Eventhandler in the VaultEntry object. 
 Does anybody know, which eventhandler is the correct one for this? 
 
 Greetings from germany

I don't know if there is an event handler that triggers when you drag and drop the file into M-Files, but there are event handlers that trigger before the object gets created. For example, "BeforeCheckInChangesFinalize" and " BeforeCreateNewObjectFinalize" triggers as soon as the user clicks the "save" button and before the object actually gets added to the vault. If you find an issue and throw an "MFScriptCancel" error message then it should prevent the user from actually saving the object to M-Files, and force them to click cancel. 
 The following M-Files page might be helpful, it shows a table of the event handlers, when they trigger, and what variables are available for use:
