Xamarin Expert Needed for Android Project -- 2

I have a Xamarin Project in Visual Studio that I need a couple of things done to 1.) I have a card that gets marked, and the mark needs to line up in the cell. Right now it overlaps the cell 2.) I have a numeric keypad that comes up where the user enters a number. Right now there are 3 steps to submit. The user types the number, hits done, and then has to hit ok on the form to submit. I just want the form to submit when the user hits done on the keypad. All work must be done on my machine via teamviewer.
