Listview will not load

Question

I have copied code from your sample app to get a simple ListView to work It aborts with:

Non-negative number required. (Parameter 'width')

I have not modified anything from the sample code and have followed the Get Started section for ListView and no matter what I try, the page containing the ListView aborts. I have been using the SfScheduler with no problems.

Any ideas?

When I looked at a page of your online documentation, it says 'Underway' for WinUI for Listview Layout...Is that the issue?

Hi Stephen, 
 
As of now, the MAUI SfListView does not have support for the Windows platform. But we are planning to provide support for Windows in our upcoming 2022 Volume 1 main release, which will be available at the end of March, 2022.  
 
You can also refer to the following link for more information on the Windows supported controls.

Please let us know if you need further assistance.

My ListView is also not loading fully (Android and Windows)

After or at loading page, listview is only showing 2-3 items instead of all 100. I have to click one time on a item to load all.

it doenst matter if there are 5, 100 or 500 items in the list. list just not loading correctly.

I have this issue now since one month.

As you can see, listview is cutted until i click once on a item.

Direct after start and loading:
