    • When IsPopupModal="True" the UI behind the popup gets inactive and cannot be used until the popup is closed.
    • When IsPopupModal="False" the popup could be closed when clicking outside the popup.

Here is a sample example that shows how the styling properties are applied.

A sample List Picker definition:

<telerikInput:RadListPicker Placeholder="Pick a City Name!"
                            ItemsSource="{Binding Items}" 
                            DisplayStringFormat="You have picked: {0}"
                            DisplayLabelStyle="{StaticResource displayLabelStyle}"
                            ItemStyle="{StaticResource ItemStyle}"
                            SelectedItemStyle="{StaticResource SelectedItemStyle}"
                            PlaceholderLabelStyle="{StaticResource placeholderLabelStyle}">
        <telerikInput:PickerPopupSelectorSettings PopupOutsideBackgroundColor="#4A4949F"
                                                  PopupViewStyle="{StaticResource popupViewStyle}"
                                                  HeaderStyle="{StaticResource headerStyle}"
                                                  HeaderLabelText="Select city"
                                                  HeaderLabelStyle="{StaticResource headerLabelStyle}"
                                                  FooterStyle="{StaticResource footerStyle}"
                                                  AcceptButtonStyle="{StaticResource acceptButtonStyle}"
                                                  CancelButtonStyle="{StaticResource cancelButtonStyle}"/>

A sample business model:

public class City
    public string Name { get; set; }
    public int Population { get; set; }

and a ViewModel:

public class ViewModel
    public ViewModel()
        this.Items = new ObservableCollection<City>
            new City { Name = "Tokyo", Population = 13929286 },
            new City { Name = "New York", Population = 8623000 },
            new City { Name = "London", Population = 8908081 },
            new City { Name = "Madrid", Population = 3223334 },
            new City { Name = "Los Angeles", Population = 4000000},
            new City { Name = "Paris", Population = 2141000 },
            new City { Name = "Beijing", Population = 21540000 },
            new City { Name = "Singapore", Population = 5612000 },
            new City { Name = "New Delhi", Population = 18980000 },
            new City { Name = "Bangkok", Population = 8305218 },
            new City { Name = "Berlin", Population = 3748000 },

    public ObservableCollection<City> Items { get; set; }

also you will need to add the following namespaces:
