Difference in display behaviour between 16.1.0.37 and 16.2.0.42 on iOS

I am using the SfListView control to display pictures on an iPad. In the initialization method for the view, I create an event handler for SizeChanged. I then define the ItemSize for the SfListView items within that SizeChanged event, to create a grid of pictures (SpanCount="4") bound to my ViewModel. I display 12 pictures on the screen at a time, with about 25 items in the collection.

This has been working fine in version 16.1.0.37, but on upgrading to 16.2.0.42, although the ItemSize is set in the SizeChanged event as before, the items are displayed with a very small height, so that the pictures do not show. The width is correct.

On subsequent refreshes (Refreshing the collection that is bound to ItemsSource), the pictures are displayed correctly. The display of the pictures on UWP is OK, not showing a problem.

For the moment I have downgraded to version 16.1.0.37.

Hi, thank-you for the reply.

I've spent some time testing this to track it down, and can actually get the problem to display on version 16.1.0.37 as well with your test sample, so I am not sure what is going on there! There must be some difference between .37 and .42 however, as the problem does not appear in my app with .37.

To reproduce the problem in your test sample:

add ItemSpacing="0,5,5,0" into the SfListView definition.
