I've made a custom entry control in Xamarin forms PCL. I can get TextChanged event with new and old Values without any problem (when entering for example digits or letters). The problem's that when I want to catch a 'backspace' on empty entry control when it's focused it simply does not trigger TextChanged event. I've found Complete event for an entry which is able to catch 'Enter' key press but there's nothing for delete/backspace. Do you have any ideas how to do that? Regards.

I think you have not to use TextChanged because if your Entry is empty you have no event fired.

Android should use setOnKeyListener to catch if a key is pressed, but it seems that it works only for hardware keyboard (and some soft keyboard)...

I think you can take a look to this question and try to create a custom renderer in C#

  • Thanks for answer but creating custom renderer for this one is just waste of time. Take a look at: https://developer.android.com/reference/android/view/View.OnKeyListener.html . Not some of the soft keyboard, but only hardware. – pjrki Mar 04 '17 at 10:21
