Insert a Label in the empty groups of the CollectionView

Question

Inside a CollectionView I have various groups, some with elements, others empty in which there is no element inside, but only the name of the group. In empty groups is it possible to insert a Label instead of the object of my class?

public class Diary
{    
     public DateTime Dt { get; set;}                          
     public string Nota { get; set; }
}

DiaryGroup hgroup = new DiaryGroup(NameGroup), new ObservableCollection<Diary>());

public ObservableCollection<DiaryGroup> TotalDiary = new ObservableCollection<DiaryGroup>();
TotalDiary.Add(hgroup);

Hello,

Welcome to our Microsoft Q&A platform!

You can add a GroupFooterTemplate for your CollectionView. You can refer to the official sample here .

Please pay attention to VerticalListEmptyGroupsPage.xaml, the code snippet is :

        <CollectionView.GroupFooterTemplate>  
            <DataTemplate>  
                <Label Text="{Binding Count, StringFormat='Total animals: {0:D}'}"  
                       Margin="0,0,0,10" />  
            </DataTemplate>  
        </CollectionView.GroupFooterTemplate>  

When the first group is empty, the result is:
