This is code in wpf which shows the tour requests, arranged in two columns:
<ListView x:Name="TourRequestsListView" ItemsSource="{Binding TourRequests}" SelectedItem="{Binding SelectedTourRequest, Mode=TwoWay}" Background="Transparent" BorderThickness="0" HorizontalAlignment="Center" Margin="10"><ListView.ItemsPanel><ItemsPanelTemplate><WrapPanel Orientation="Horizontal" /></ItemsPanelTemplate></ListView.ItemsPanel><ListView.ItemTemplate><DataTemplate><StackPanel Margin="10"><Border BorderBrush="White" Background="#05085B" BorderThickness="2" CornerRadius="10" Width="500" Height="225"><StackPanel><Border Background="{Binding State, Converter={StaticResource StateToBackgroundConverter}}" Margin="25,20,0,0" BorderBrush="White" HorizontalAlignment="Left" BorderThickness="2" CornerRadius="10" Width="250"><DockPanel><TextBlock Text="Status: " Margin="15,5,0,5" FontSize="18" FontWeight="Bold" FontFamily="Helvetica" Foreground="White"/><TextBlock Text="{Binding State}" Margin="0,5,5,5" FontSize="18" FontWeight="Bold" FontFamily="Helvetica" Foreground="White"/></DockPanel></Border><DockPanel><Image Source="/wpf/icons/touristicons/schedule.png" Margin="25,20,0,0" Width="30" VerticalAlignment="Center"/><TextBlock FontSize="18" FontFamily="Helvetica" Foreground="White" Margin="5,20,0,0" VerticalAlignment="Center"><Run Text="Creation Date: " /><Run Text="{Binding CreationDate}" /></TextBlock></DockPanel><DockPanel><Image Source="/wpf/icons/touristicons/number-blocks.png" Margin="25,20,0,0" Width="30" VerticalAlignment="Center"/><TextBlock FontSize="18" FontFamily="Helvetica" Foreground="White" Margin="5,20,0,0" VerticalAlignment="Center"><Run Text="Number of simple tour requests: " /><Run Text="{Binding NumberOfRequests}" /></TextBlock></DockPanel><Button Content="See Details" Margin="0,20,0,0" Command="{Binding ElementName=TourRequestsListView, Path=DataContext.SeeDetailsCommand}" CommandParameter="{Binding}" HorizontalAlignment="Center" BorderBrush="Transparent" Background="Transparent" VerticalAlignment="Center"><Button.Template><ControlTemplate TargetType="Button"><TextBlock Text="{TemplateBinding Content}" TextDecorations="Underline" Cursor="Hand" FontFamily="Helvetica" FontSize="20" Foreground="Yellow"/></ControlTemplate></Button.Template></Button></StackPanel></Border></StackPanel></DataTemplate></ListView.ItemTemplate></ListView>ItemsSource is binded to TourRequests and SelectedItem to SelectedTourRequestC# (DataContext set to this viewModel):
private ObservableCollection<ComplexTourRequest> _tourRequests;public ObservableCollection<ComplexTourRequest> TourRequests{ get { return _tourRequests; } set { _tourRequests = value; OnPropertyChanged("TourRequests"); }}private ComplexTourRequest _selectedTourRequest;public ComplexTourRequest SelectedTourRequest{ get { return _selectedTourRequest; } set { _selectedTourRequest = value; OnPropertyChanged("SelectedTourRequest"); }}viewModel extends class with propertyChanged implementation:public class ReviewComplexTourRequestsViewModel : TouristViewModel
TouristViewModel.cs:
public class TouristViewModel : INotifyPropertyChanged{ [field: NonSerialized] public event PropertyChangedEventHandler PropertyChanged; protected void OnPropertyChanged([CallerMemberName] string name = null) { PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name)); }}When I debug, when clicking on an element from the list, only the get method is called, but not the set method, and selectedRourRequest returns null
