Xamarin Solutions

To track my solutions for Xamarin.Forms

Shell

• Fully Custom tabbar (support badge, colorfull icon etc)
• Scroll Position Reset Issues (on Android)
  • Issues 1, Issues 2
  • Tried reset Scroll Position (include reflect method) but failed
  • No solution yet
• Custom Flyout Panel
  • Update : Bad user experence, use Custom Side Drawer instead.
• Flyout right side

ScrollView

• To enable scroll
  • Padding > 0 (recommend 1 or 0.1, otherwise when stop may hide partical header)
  • If StackLayout as child, VerticalOptions<>"Start"
  • Set child's padding to keep space
• Case layout over head when use as root
  • Wrap by AbsoluteLayout to fix it

Frame

• Corner Radius not show on iOS sometimes
  • Make sure child element has margin, same value (can only set XY) as CornerRadius
  • My case is StackLayout as child

Side Drawer

• Custom Side Drawer
  • No render, no third party lib

Erros

• Specified cast is not valid
  • Check xaml bindings
  • Check if you push a page, with NavigationPage

  await Navigation.PushAsync(new **NavigationPage**(new SomeContentPage()));

Debug

• [Android] data wiped everytime uninstall
  • Turn off backup via Settings -> System -> Backup, turn off whaterver backup provider(mine is Google Drive)
