XAML 윈도우 폰 8

Question

내가 예를 날짜로 수평으로 내 해당 페이지에서 데이터베이스에서 6 개 값을 보여 드리고자 | 시간 | 층 | 지역 | 위도 | 경도 그러나 페이지는 데이터를 보여줍니다 | 시간 | 바닥을 | 지역 와 위도를 표시하지 않고 아래 경도 내 XAML 코드

<Grid x:Name="LayoutRoot" Background="Transparent"> 
    <Grid.RowDefinitions> 
     <RowDefinition Height="Auto"/> 
     <RowDefinition Height="*"/> 
    </Grid.RowDefinitions> 

    <!--TitlePanel contains the name of the application and page title--> 
    <StackPanel Grid.Row="0" Margin="12,17,0,28"> 
     <TextBlock Text="Smart Parking" Style="{StaticResource PhoneTextNormalStyle}"/> 
     <TextBlock Text="History" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/> 
    </StackPanel> 
    <!--ContentPanel - place additional content here--> 
    <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0"> 
     <ListBox x:Name="ListData"> 
      <ListBox.ItemTemplate> 
       <DataTemplate> 
          <StackPanel Orientation="Horizontal"> 
          <TextBlock x:Name= "DateTxt" Text="{Binding Date}" TextWrapping="Wrap" /> 
          <TextBlock x:Name= "TimeTxt" Text="{Binding Time}" TextWrapping="Wrap" /> 
          <TextBlock x:Name= "ZoneTxt" Text="{Binding Zone}" TextWrapping="Wrap"/> 
          <TextBlock x:Name= "FloorTxt" Text="{Binding Floor}" TextWrapping="Wrap"/> 
          <TextBlock x:Name= "LatTxt" Text="{Binding location_latitude}" TextWrapping="Wrap" /> 
          <TextBlock x:Name= "LongTxt" Text="{Binding location_longitude}" TextWrapping="Wrap" /> 
         </StackPanel> 
       </DataTemplate> 
      </ListBox.ItemTemplate> 
     </ListBox> 
    </Grid> 
</Grid> 

사람은 내가 그것을 그것을 개선 또는 수정 도와 주실 수 있습니까?

목록 itmesource에 대한 뒤에 코드는 여기에 아래의 모든 주요 기능

Answer 1

귀하의 텍스트 블록을 location_longitude에 바인딩하고 있는데 위치가 표시되지 않습니다. 경도 (또는 위도)를 코드 뒤에 표시합니다.

플러스, 당신은 당신의 Longitude 및 Latitude 선언에서

<TextBlock x:Name="LatTxt" Text="{Binding Latitude}" TextWrapping="Wrap" /> 
<TextBlock x:Name="LongTxt" Text="{Binding Longitude}" TextWrapping="Wrap" /> 

희망이 도움말로 된 본체를 결합하는

public double longtitude // Here change to Longitude 
    { 
     get { return this.lonValue; } 
     set 
     { 
      if (value != this.lonValue) 
      { 
       this.lonValue = value; 
       NotifyPropertyChanged("Longitude"); 
      } 
     } 
    } 

private double latValue; 
    public double latitude // Change to Latitude 
    { 
     get { return latValue; } 
     set 
     { 
      if (value != this.latValue) 
      { 
       this.latValue = value; 
       NotifyPropertyChanged("Latitude"); 
      } 
     } 
    } 

시도를 조금 철자가 있습니다.
