Bug: TabView content disappears after dragging. #2455

dpaulino · 2020-05-16T06:24:38Z

I set up a tabview by binding an observable collection to the control's TabItemsSource. I then tried dragging tabs around, but the content disappears after dragging. I'm not sure if this is a bug or if I'm just not using the control properly. Can someone help?

@dpaulino I don't see this issue in XamlControlsGallery. Do you have a style for TabViewItem ? Is there something else different about your app ? Can you see if you can repro it in a blank uwp app and if so can you share the repro ?

dpaulino · 2020-05-16T17:44:53Z

@ranjeshj Here's a sample app with full repro instructions and video in the readme: https://github.com/dpaulino/tabview-content-disappearing

repro video https://streamable.com/c4nbil

Repro steps

Clone this repo
Open in VS2019 and launch by pressing F5
Window opens with two tabviews in the app, one at the top half of the page and another at the bottom half of the page.
- The top half is a tabview that works fine (content does not disappear on tab rearrange).
- The bottom half is a tabview that is broken.
Test top half
- Press new tab (+) button twice to open two tabs.
- Drag and drop to rearrange the tabs. The text "Content Page" does not disappear.
Test bottom half
- Press new tab (+) button twice to open two tabs.
- Drag and drop to rearrange the tabs
- The text "Content Page" disappears. It should NOT disappear.

The main difference between the two tabviews is that the broken tabview uses TabItemsSource. Should developers not be using that property with the TabView? Or is the expectation that the TabView performs identically whether or not a developer uses TabItemsSource?

marcelwgn · 2020-05-17T08:58:29Z

It looks like we are setting the content of the tabviewitem to null when it get's dropped onto the TabView again. That is definitely a bug.

StephenLPeters · 2020-05-20T22:49:37Z

@chingucoding do you already have context on the fix? If so do you want to tackle it?

marcelwgn · 2020-05-20T23:29:53Z

@StephenLPeters Looking at the code, there does not seem to be any change of a TabViewItems content inside the TabView control, but I can take a closer look when exactly the values changes.

marcelwgn · 2020-05-23T01:00:53Z

So I've added a callback change to the TabViewItem's content property, and the stacktrace for setting the content to null is this:

MUXControlsTestApp.exe!MUXControlsTestApp.TabViewPage.tabItemContentChanged(Windows.UI.Xaml.DependencyObject sender, Windows.UI.Xaml.DependencyProperty dp) Line 84	C# <--- DP change call back
[External Code]

Microsoft.UI.Xaml.dll!winrt::impl::produce<TabViewListView,winrt::Windows::UI::Xaml::Controls::IControlOverrides>::OnDrop(void * e) Line 30099	C++
[External Code]

So maybe this is ListView interfering here? Or is this something even further down the UI stack?

ranjeshj · 2020-05-27T15:52:47Z

@chingucoding can you right click, say show external code and load symbols for windows.ui.xaml and see if that gives you a better stack ?

marcelwgn · 2020-05-27T18:52:20Z

Using show external code, I get the following stacktrace:

ranjeshj · 2020-05-28T13:59:30Z

Still missing symbols. @RBrid can you help investigate this issue ?

RBrid · 2020-05-29T20:52:00Z

A few observations:

the bug does not repro when turning off OS animations. Same as for Issue App crashes when rearranging tabs in TabView where TabItemsSource is used #2457.
the fix described in Fix for Issue#2457 - Crash when rearranging TabView tabs bound to UIElements WinUI-Gallery#457 fixes this bug too. That is removing the inner ListView ItemContainerTransitions' AddDeleteThemeTransition/ContentThemeTransition animations.
