RefreshView TapGestureRecognizer Event does not respond on iOs for items which are only visible after scrolling

[Yannikk1996]

Description

In a RefreshView the TapGestureRecognizer Event does not respond on iOs for items which are only visible after scrolling. The TapGestureRecognizer Event works for the first items which can be displayed on the screen but for the items which can only be reached by scrolling down the TapGestureRecognizer Event will not be triggered. This happens when items created in xaml and also when added in c# code.

This also happens when using Scrollview. For Scrollview this only happens when adding items after its creation. Therefore recreating the complete scrollview control is a possible workaround.

This issue occurs on iOS. Windows and Android work as expected.

Hey,

I created a minimal sample project and the GitHub repo is linked.

Best regards

We are also encountering the exact same issue - on iOS only, and only for items which are only visible after scrolling - the click events do not work. Currently it's holding up being able to use the RefreshView at all on an important screen

#14795 maybe similiar issue

[Yannikk1996]

Ipad is not affected.

Hey,
I have the exact same issue and didn't find a workaround. This makes it almost useless to use the RefreshView.

Gestures now work when the device orientation is rotated causing the entire screen to redraw.
If you can do the same, you may be able to avoid this. But what should we do?

[Yannikk1996]

Hi , I found the workaround from #14624 can work by using an additional Grid between Refresh and scrollview.

[cat0363]

It worked with the code below.
The name of the control is the one in the source code you uploaded.

stack.SizeChanged += (object sender, EventArgs e) =>
{
    Refresh.ForceLayout();
};

@cat0363 thanks!

Verified this issue with Visual Studio Enterprise 17.7.0 Preview 1.0. Can repro on iOS platform with sample project.

This workaround works fine. Thanks!
