Handle event when Label Text Change

Question

I\'m developing App which communicate with RFID Reader, I have the following Label which takes it\'s value from the Reader (when I click on the read button on the hardware)

Answer 1

What you can do is on whatever page/view your label is on create a new bindableproperty that is set to your binding. Then add a propertyChanged method that will get called if the text on your label changes.

 public static BindableProperty TextChangedProperty = BindableProperty.Create(nameof(TextChanged), typeof(string), typeof(YourView), string.Empty,  propertyChanged:OnTextChanged);

 public string TextChanged
 {
     get { return (string)GetValue(TextChangedProperty); }
     set { SetValue(TextChangedProperty, value); }
 }

 static void OnTextChanged(BindableObject bindable, object oldValue, object newValue)
 {
    //Do stuff
 }
