[Bug] [UWP] CollectionView with header and footer displays only white page until resize #13981

Open SuNNjek opened 3 years ago

SuNNjek commented 3 years ago

Description

When a page has a horizontal CollectionView with a header and a footer the entire page content is white until the window gets resized. I tried this with a couple of Xamarin.Forms versions and this only seems to happen on versions >=5.0 Might be related to #11732, but my issue only starts appearing on 5.0, 4.8 works as expected.

Steps to Reproduce

  1. Run the attached project on UWP
  2. The page is completely white
  3. Resize the window
  4. Page content is displayed

Expected Behavior

The page should show up immediately and not show a white screen

Actual Behavior

The page doesn't render until the window is resized

Workaround

holecekp commented 2 years ago

I have the same problem. If there is anything visible in the CollectionView.Header, only blank page is displayed on UWP.

kyurkchyan commented 2 years ago

Having the same problem. Setting footer in UWP renders the CollectionView blank

drossoft commented 2 years ago

Same problem (version 5.0.0.2337). Setting content in CollectionView.Header or CollectionView.Footer causes random blank page. Sometimes it displays correctly, sometimes the whole page is blank, and sometimes it displays all controls on the page except the CollectionView.

drossoft commented 2 years ago

Struggling to understand this, I can't get to understand this random rendering behavior, is there any workaround please?

chaoyebugao commented 2 years ago

Same problem... All blank exception navigation bar when I added the footer. So weird...
