Input errors on Xamarin
Users should be notified when they make input errors. Show a clear error message when data has been entered incorrectly. Furthermore, provide suggestions that help users to fix the error. It is important that error messages are also posted to users of assistive technologies.
In Xamarin.Forms, we recommend using a Label
to display an error. The error message should also be posted to assistive technologies by using an accessibility announcement
.
<Label
Text="Invalid date, must be in the form DD/MM/YYYY, for example, 01/01/2000"
IsVisible="{Binding IsValid}" />
