何らかの理由で UI が RaisePropertyChanged に応答できません。よく立ち往生。CurrentClient は UI に発火しない部分です。本当に奇妙です。うまくいけば、誰かが私を助けてくれます。ありがとうスコット
public class ClientViewModel : ViewModelBase
{
public RelayCommand<ClientDetail> SelectedClient { get; private set; }
public ICollectionView ClientView { get; private set; }
private readonly IClients _clientsService;
public ClientViewModel(IClients clientsService)
{
_clientsService = clientsService;
SelectedClient = new RelayCommand<ClientDetail>(InSelectedClient);
ClientDetailsList = new ObservableCollection<ClientDetail>(_clientsService.LoadClientList());
//CurrentClient = ClientDetailsList.ToList().FirstOrDefault();
ClientView = CollectionViewSource.GetDefaultView(ClientDetailsList);
}
private void InSelectedClient(ClientDetail obj)
{
CurrentClient = obj as ClientDetail;
}
private ObservableCollection<ClientDetail> _clientDetailsList;
public ObservableCollection<ClientDetail> ClientDetailsList
{
get { return _clientDetailsList; }
set { _clientDetailsList = value;
RaisePropertyChanged("ClientDetailsList"); }
}
private ClientDetail _currentClient;
public ClientDetail CurrentClient
{
get { return _currentClient; }
set
{
if (_currentClient == value)
{ return; }
_currentClient = value;
RaisePropertyChanged("CurrentClient");
}
}
}
私のXAML:
<ListBox Name="lbClientList"
ItemsSource="{Binding ClientView}" ItemTemplate="{DynamicResource DTClientList}"
Background="{x:Null}" BorderThickness="0,0,1,0" BorderBrush="#FF434343" >
<ListBox.Resources>
<DataTemplate x:Key="DTClientList">
<StackPanel Orientation="Horizontal">
<TextBlock TextWrapping="Wrap" Text="{Binding CM_CompanyID}" Margin="0,0,5,0" Width="25" Foreground="#FF3590FC"/>
<TextBlock TextWrapping="Wrap" Text="{Binding CM_CompanyName}" Width="150" Foreground="#FF3590FC"/>
<TextBlock TextWrapping="Wrap" Text="{Binding CM_MainContact}" Width="100" Foreground="#FF3590FC"/>
</StackPanel>
</DataTemplate>
</ListBox.Resources>
<i:Interaction.Triggers>
<i:EventTrigger EventName="SelectionChanged">
<Command:EventToCommand Command="{Binding SelectedClient, Mode=OneWay}" CommandParameter="{Binding SelectedItem, ElementName=lbClientList}"/>
</i:EventTrigger>
</i:Interaction.Triggers>
<ListBox.DataContext>
<Binding Path="ClientView" Source="{StaticResource ServiceLocator}" UpdateSourceTrigger="PropertyChanged"/>
</ListBox.DataContext>
</ListBox>
デバッグでは、コードは RaiseProertyChange をヒットしていますが、UI に何も表示されません
<TextBox Text="{Binding CurrentClient.CM_Address1}" TextWrapping="Wrap" VerticalAlignment="Center" Width="210" Background="{DynamicResource MainBackgrouund}" BorderThickness="0,0,0,1" >
