Answer 2

Side note: It would be great if you posted only code relevant to your question. (OTOH too much code is better than too little.)

You're assigning files which is a File to DataGrid.ItemsSource (indirectly through binding and DataContext). But ItemsSource needs a collection of items, not just one item.

If you change the second line in the event handler to:

this.dataGridElencoFiles.DataContext = new File[] { files };

the DataGrid shows with some columns (like “Percorso” or “NomeFile”), but prints only “(Collection)” in each of them. The DataGrid can't show that formatted as a table, because each of those collections could have different length and there is no indication that they are related.

Instead, you should have a class that represents one file and give list of those to the DataGrid. I would rename your File class to something like Directory and add a method that returns collection of files from it. Or implement IEnumerable<your_file_class>.
