XamaWIN – Controlling the Back Button Text

Xamawin • zam-ah win | noun
A quick, easy to implement enhancement for a Xamarin App that improves performance, appearance, or functionality

Have you ever wanted to change the back button text in the navbar for iOS in Xamarin.Forms? I certainly have; by default the text is set to be the title of the previous page. Now, maybe I’m not good at Googling things, but I finally stumbled across the solution! As usual, my salvation came from a James Monetmagno Post. Thanks to the magic of Attached Properties we can access properties from the NavigationPage that hosts out ContentPage. Specifically, we want to modify a property called “BackButtonTitle”. Setting via our xaml is a cinch:

<?xml version="1.0" encoding="UTF-8"?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms" 
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" 
    x:Class="PrismForms.Views.HomePage" 
    Title="{Binding Title}"
    NavigationPage.BackButtonTitle="Return">
    <ContentPage.Content>

We can also do it in the code behind:

NavigationPage.SetBackButtonTitle(this, "Return");

Either way, the end result is a back button that says exactly what we want it to!
