Is the default drop handler muteable?

Question

Hi,

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

correct.

So, with the fix it will be possible to suppress the message and also to implement my own handling without calling the default handling?

Max, sorry for the response delay. This has been fixed for 2.3.1. 2.3.1 will be available at the end of March (2019)
