I want an event to be triggered when a new file is loaded.
Where and how is the file "loaded"?
I put filepathin: value Change into the Event structure, but this does not work.
How is the value change event of the filepath control related to your "new file is loaded"?
the file is loaded through a file path control in the front panel. The file contains some data which I want to be displayed as soon as I select a new file.
when you select a (new) file with your filepath control you should get a value change event for it.
In the event you should load your data.
When you handle things different in your VI then you should attach this VI - that's the way to get better answers here!
