Is the default drop handler muteable?

I am implementing a custom configuration based on ArcGIS Pro and I have to implement a drop handler for my map pane to accecpt custom Excel files.

But I always get an error message box telling me, that the import of data has failed:

"Failed to add data, unsupported data type"


I first thought this is caused by my own implementation, but it is not. There seems to be a default drop handler (because I also get the error in an unmodified ArcGIS Pro instance) and I would like to know how I could remove this one.


I know my files have a custom format, thats why I'd like to implement my own handlers.


Any hints?


Kind regards, Max
