Hi Vardan,

Please note that the behavior you have initially reported in this feedback item is related to the situation that the ListView displays a blank item, doesn't hide it, and an exception occurs. As I explained the blank item is expected for the ListView control, the behavior also occurs in the Xamarin CollectionView.

From your last reply you have mentioned a button inside the listview itemtemplate, a converter, so it seems that you have a different page definition. -> As a next step, I can suggest you open a support ticket and attach a stripped-down version of the project you are working on, so I can be aware of the exact setup you have. Then I can research the case further and check whether this behavior is expected.

Thank you for the understanding.

Hi Vardan,

Thank you for the provided files and detailed explanation of the behavior. 

I understand your point, still, this is how the ListView handles the items and the behavior you are observing is expected. 

Empty item will be visualized because it is a valid item no matter whether there is a value for the name property.

This is an item that the Telerik UI for Xamarin RadListView 

new City {Name = null, Country = "Empty Item", Description = null},

and

Xamarin.Forms CollectionView:

Cities.Add(new CountryGroup("Empty Item", new List<City>
{
    new City
    {
        Name = null,
        Description = null
    },
}));

will display as an empty item. 

I have changed the status of the bug report to declined. As the behavior is expected. 

I hope the provided information was helpful.
