[mono-android] Dialog Box Button click code?

[Tomasz Cielecki]

Have you tried using the dialogs FindViewById method?

i.e.

var button = (Button)dialog.FindViewById(Resource.Id.btnMonthSubtract);

If you are just using FindViewById in the activity, you won't find the
button as you are looking at the Activity Content View and not the
Dialog Content View. Then the button resolves to null and you get the
NullReferenceExceptions.
