Activity before Filepicker

[Hirobo_dev]

I am trying to develop an application that allows the user to read files, and I solved it using FilePicker.

I would like to run a series of checks before the FilePicker window opens, and if all ok proceed otherwise exit.

Do you know how I can solve this?

Thank you very much

Then write the checks in the BeforePicking block, right?

Writing the check in BeforePicking doesn't solve the problem about not opening the FilePicker window, moreover, it doesn't execute any check

Anyway, the notification will not be displayed before the Action so, may be you can use other button to execute the validations and, if all is ok, call to FilePicker.Open procedure.

You can "hide" de FilePicker so only one button is shown.

Something like this:
