DataTemplate으로 사용하면 렌더링되지 않는 사용자 정의 컨트롤?

Question

ListBox에서 DataTemplate으로 사용하려는 usercontrol이 있습니다. 나는 <DataTemplate> 태그 사이에서 동일한 코드를 넣으면

<ListBox> 
    <ListBox.ItemTemplate> 
     <DataTemplate> 
<Grid x:Name="Grid" Height="100" Width="880" Background="LightGray"> 
    <Grid.RowDefinitions> 
     <RowDefinition Height="24"/> 
     <RowDefinition Height="24"/> 
     <RowDefinition Height="24"/> 
     <RowDefinition Height="24"/> 
    </Grid.RowDefinitions> 
    <Grid.ColumnDefinitions> 
     <ColumnDefinition Width="190" /> 
     <ColumnDefinition Width="100" /> 
     <ColumnDefinition Width="100" /> 
     <ColumnDefinition Width="100" /> 
     <ColumnDefinition Width="190" /> 
     <ColumnDefinition Width="200" /> 
    </Grid.ColumnDefinitions> 
    <Label Grid.Column="0" Grid.Row="0">Client</Label> 
    <Label Grid.Column="0" Grid.Row="2">Contact</Label> 
    <Label Grid.Column="1" Grid.Row="0">Date Presentation</Label> 
    <Label Grid.Column="2" Grid.Row="0">Action</Label> 
    <Label Grid.Column="3" Grid.Row="0">Date Interview</Label> 
    <Label Grid.Column="3" Grid.Row="2">Time Interview</Label> 
    <Label Grid.Column="4" Grid.Row="0">Remarks</Label> 
    <Label Grid.Column="5" Margin="0,0,2,0">managed by</Label> 
    <ComboBox Grid.Column="0" Grid.Row="1" Margin="2" Text="{Binding Path=Customer}"> 
     <!--Template--> 
    </ComboBox> 
    <TextBox Grid.Column="0" Grid.Row="3" Margin="2" Text="{Binding Path=Contact}"></TextBox> 
    <TextBox Grid.Column="1" Grid.Row="1" Margin="2" Text="{Binding Path=PresentationDate}"></TextBox> 
    <ComboBox Grid.Column="2" Grid.Row="1" Margin="2" Text="{Binding Path=Action}"> 
     <!--Template--> 
    </ComboBox> 
    <TextBox Grid.Column="3" Grid.Row="1" Margin="2" Text="{Binding Path=InterviewDate}"></TextBox> 
    <TextBox Grid.Column="3" Grid.Row="3" Margin="2" Text="{Binding Path=InterviewTime}"></TextBox> 
    <TextBox Grid.Column="4" Grid.Row="1" Grid.RowSpan="3" Margin="2" Text="{Binding Path=Remarks}"></TextBox> 
    <StackPanel Orientation="Horizontal" Grid.Column="5" Grid.Row="1" > 
     <ComboBox Width="124" Text="{Binding Path=Manager}" Margin="2"></ComboBox> 
     <Button Width="60" Height="20" Margin="4,0,0,0" >Mail</Button> 
    </StackPanel> 
    <CheckBox Grid.Column="5" Grid.Row="3" Margin="2,2,4,2">Rejection communicated</CheckBox> 
    </Grid> 
     </DataTemplate> 
    </ListBox.ItemTemplate> 
</ListBox> 

:

이 작동 CandidatePresentationControl라는 이름의 UserControl을에

    Height="100" Width="880" BorderBrush="Black" BorderThickness="1">

     </StackPanel> 
     <CheckBox Grid.Column="5" Grid.Row="3" Margin="2,2,4,2">Rejection communicated</CheckBox> 
     </Grid> 

</UserControl> 

및

<ListBox> 
    <ListBox.ItemTemplate> 
     <DataTemplate> 
      <Grid> 
       <vw:CandidatePresentationControl/> 
      </Grid> 
     </DataTemplate> 
    </ListBox.ItemTemplate> 
</ListBox> 

처럼 할

렌더링되지 않습니다. 오류가없고 단지 빈 목록 상자. 누군가가 나를 도울 수 있습니까 ??

감사합니다.

편집 : 나는 뭔가를 잊어 버렸어. 중요하다면 몰라. 내가하고있는 모든 일은 usercontrol이기도하다.

Answer 1

참조 된 UserControl이 다른 UserControl 내에 있다는 것은 중요하지 않습니다. http://beacosta.com/blog/?p=52

데이터가 XAML에 하드 연결되어 있으므로 비어있는 ListBox를 설명하는 유일한 방법은 부모 UserControl에서 UserControl을 찾을 수 없다는 것입니다. imo .

Answer 2

<ListBox> 
    <ListBox.ItemTemplate> 
     <DataTemplate> 
      <Grid> 
       <vw:CandidatePresentationControl DataContext="{Binding}"/> 
      </Grid> 
     </DataTemplate> 
    </ListBox.ItemTemplate> 
</ListBox> 

당신은 데이터 컨텍스트를 결합하기 위해이 방법을 쓸 필요가, 당신은 당신에게 더 나은 방법을 수행하는 방법에 대한 아이디어를 줄 것이다 MVVM 봐 제안.
