[UWP]TextBox.IsReadOnly = true - crash app

Question

Hi All,

If set TextBlock.IsReadOnly to true - I'll get app crash.

Windows 10 Version 1511 (OS Build 14316.1000)

No problem on Windows 10 Mobile 10586 build

Answer 1

TextBlock is for displaying text.  You cannot edit text in a textblock.  Why do you need to set the property?

Answer 2

A UWP TextBlock doesn't have any IsReadOnly property: https://msdn.microsoft.com/sv-se/library/windows/apps/br209652

The TextBox class has but setting this shouldn't crash the app: https://msdn.microsoft.com/sv-se/library/windows/apps/xaml/windows.ui.xaml.controls.textbox.isreadonly.aspx

Hope that helps.

Answer 4

@Alexey.U,

I think that textbox should not cause this issue. Is it a new simple project?

Please test this, if it is a new simple project which can reproduce this issue. Please repair your Visual Studio and Windows SDK.

If only your old project can reproduce this issue, I think you need to clean and rebuild your project.

Best regards,

Barry

Hi Alexey,

This is a known bug with the OS (not with VS or the SDK), but I would encourage you to test with the 14332 Insider Fast version of the OS which was just announced today. The new OS should have the fix in it. Please let me know how it goes.

Thanks,

Prashant
