本土组合框不显示选择正确

Question

编辑：看来ListPicker是要走的路，但我有更多的问题与详细Microsoft.Phone.Controls.Toolkit ListPicker throws XamlParseException

我有以下代码组合框：

<ComboBox x:Name="Result" Grid.Column="6" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="Black" Background="White"> 
    <ComboBoxItem Content="Win" /> 
    <ComboBoxItem Content="Place" /> 
    <ComboBoxItem Content="Lose" /> 
</ComboBox> 

但它并不像我预期的那样显示。当你下拉组合框时，选项不会出现，就像空项目一样。见下文：

然而，当一个项目被选中时，它显示正确并返回正确的索引/项目。请看下图：

我敢肯定有一些简单的我已经错过了，但不能把我的手指上。

编辑：好吧我张贴完整的代码。我有一个用户控制，OddsRow，看起来像这样：

<UserControl xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit" x:Class="MojoPinBetOddsCalculator.OddsRow"

    Foreground="{StaticResource PhoneForegroundBrush}" 
    d:DesignHeight="480" d:DesignWidth="480"> 

    <Grid x:Name="LayoutRoot" Background="{StaticResource PhoneChromeBrush}"> 
     <Grid.RowDefinitions> 
      <RowDefinition Height="70"/> 
     </Grid.RowDefinitions> 
     <Grid.ColumnDefinitions> 
      <ColumnDefinition Width="50*"></ColumnDefinition>

      <ColumnDefinition Width="70*"></ColumnDefinition> 
      <ColumnDefinition Width="70*"></ColumnDefinition> 
      <ColumnDefinition Width="70*" ></ColumnDefinition> 
      <ColumnDefinition Width="100*"></ColumnDefinition> 
     </Grid.ColumnDefinitions> 
     <TextBlock x:Name="RowNumber" Grid.Column="0" VerticalAlignment="Center" HorizontalAlignment="Center"></TextBlock> 
     <TextBox x:Name="OddsNumerator" Grid.Column="1" Width="90" Height="70" HorizontalAlignment="Center" TextAlignment="Center" VerticalAlignment="Center" MaxLength="3" InputScope="TelephoneNumber"></TextBox> 
     <TextBlock x:Name="Slash" Grid.Column="2" Text="/" HorizontalAlignment="Center" VerticalAlignment="Center"></TextBlock> 
     <TextBox x:Name="OddsDenominator" Grid.Column="3" Width="90" Height="70" VerticalAlignment="Center" TextAlignment="Center" MaxLength="3" HorizontalAlignment="Center" InputScope="TelephoneNumber"></TextBox> 
     <CheckBox x:Name="EachWay" Grid.Column="4" VerticalAlignment="Center" HorizontalAlignment="Center" Margin="10,0,0,0" /> 
     <CheckBox x:Name="Place" Grid.Column="5" HorizontalAlignment="Center" VerticalAlignment="Center" BorderThickness="0" Width="71" Margin="10,0,0,0" Padding="0" /> 
     <ComboBox x:Name="Result" Grid.Column="6" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="Black" Background="White">

      <ComboBoxItem Content="Place" /> 
      <ComboBoxItem Content="Lose" /> 
     </ComboBox> 
    </Grid> 
</UserControl> 

而且它显示在的MainPage像这样：

分别组合框的作品，也是代号为OddsRow作品如预期......分开。合并后不显示这些项目。

OddsRow.xaml.cs

public partial class OddsRow : UserControl 
{ 
    private int m_Row; 

    public OddsRow() 
    { 
     InitializeComponent(); 
    } 

    public int Row 
    { 
     get 
     { 
      return m_Row; 
     } 
     set 
     { 
      m_Row = value; 
      RowNumber.Text = m_Row + " - "; 
     } 
    } 
}

一切的爱，请不要使用股票组合框。使用类似ListPicker的东西。它将使您的应用程序看起来与Metro UI更加一致。
