Description Hakan 2017-04-16 18:24:10 UTC
When entry.Focus() is used in a tap event handler, it works in Android but fails in iOS. Here is a sample xaml:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"


        <Entry Keyboard="Numeric" x:Name="entry" IsVisible="False" Text=""></Entry>
        <BoxView BackgroundColor="Blue">
                <TapGestureRecognizer Tapped="TapGestureRecognizer_OnTapped"></TapGestureRecognizer>



Here is App.xaml.cs:

MainPage = new NavigationPage(new App.TapTest());

Here is TapTest.xaml.cs

        private void TapGestureRecognizer_OnTapped(object sender, EventArgs e)

But when I use the work-araounds below, it somehow starts to work:

if (codeEntry.IsFocused == false)


await Task.Delay(1);

I do not actually understand why these work. I discovered them by trial and error.

repro project

I'm attaching a project the reproduces the issue and confirming the report so the team can investigate further. 

This seems to be happening on iOS and UWP, but it's unclear if this is expected behavior on these platforms as the issue does not happen if the Entry is visible instead of invisible like in the repro project. The workarounds mentioned in the description also only work for iOS, not UWP.

### Regression Test
2.3.5-pre1  BAD   BAD   BAD

Calling Focus() for me works on iOS using the latest release version of Xamarin Forms  What I'm running into now is that if I open a page that Focus() got called on for an entry, and then leave that page, and then re-enter that same page or any other page with an Entry even if I tap on the Entry it cannot get focus again.

I am also getting this behavior

I added this to work around:

await Task.Delay(1);
Comment 4 Sean Knox 2018-02-24 13:29:04 UTC
This behaviour is still present in UWP in Xamarin

I have for the time being applied the work around above
