Hi,
I rolled my app with the ListView out to production and are getting 8+ crashes a day from 140 users with the above issue. I have included a stack trace. I cannot find the steps to reproduce the issue in development. I have rolled back to using the native ListView as this does not crash the app.
Attached is an example project to see what I am doing in general terms, but I have not been able to reproduce this crash in it.
My guess is that a DataTemplate is not being cleaned up properly and when the data behind is changed it attempts to access the control that represented the data in the DataTemplate.
Regards
Anthony
Please refer to the attached project that reproduces the issue. In the MainPage constructor, you can switch between using the PickerEditor (validation works) and the SegmentedEditor (validation doesn't work).
// Works with validationdataForm.RegisterEditor("Location", EditorType.PickerEditor);// Doesn't work with validation//dataForm.RegisterEditor("Location", EditorType.SegmentedEditor);This leads to other issues like the PropertyValidationCompleted event not firing.
Thank you,
Mohamed
If you have a Chart with BarSeries and TooltipBehavior defined, the tooltip of each bar is shown only when the user taps in the area around the tip of the bar.
The expected behavior is the tooltip to be displayed when clicking anywhere on the bar.
When RadCalendar is inside Xamarin Forms Tabbed Page. Switching between tabs triggers Calendar SelectionChanged and the calendar DisplayDate is changed.
Workaround:
the issue could not be reproduced when RadTabView is used and its IsContentPreserved property is set to true.
The pdf content is not visualized properly on UWP and iOS when the file is loaded from a stream.
Also if you try to load PDF twice on the same PDF Viewer, an exception is raised.
In Xamarin Forms.
When I call Calendar.ScrollAppointmentIntoView(theItem); in Android it works fine.
In iOS when the same call is made, the calendar scrolls about 1 pixel, then stops.
I put the call into a timer just to make sure it's there.
Device.StartTimer(TimeSpan.FromMilliseconds(3000), () =>
{ Device.BeginInvokeOnMainThread(() => { Calendar.ScrollAppointmentIntoView(theItem); });
return false; // True = Repeat again, False = Stop the timer
});
If customers set bindings to these properties and try to set range from negative to positive values (e.g. from -0.5 to 0.5) the bindings are not applied as expected.
When there is custom template applied that hosts multiple rows of UI components with total height greater than 44, the template is not measured correctly, leading to wrong visualization.
