Yes, you could open the filter dialog by pressing a key combination, or a button.
If your GridView is named clubsGrid, you may show the filtering window from the code like this:
var firstFilteringDropDown =
What you need to additionally do is to create a command, that calls this code when the combination of Alt+C occurs.
With this XAML, we have added what imput gestures will trigger the command. Now, if the window has focus, and you hit Alt+C , the command "ShowFilter" will get executed.
