本土組合框不顯示選擇正確

Question

編輯：看來ListPicker是要走的路，但我有更多的問題與詳細Microsoft.Phone.Controls.Toolkit ListPicker throws XamlParseException

我有以下代碼組合框：

<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> 

但它並不像我預期的那樣顯示。當你下拉組合框時，選項不會出現，就像空項目一樣。見下文：

然而，當一個項目被選中時，它顯示正確並返回正確的索引/項目。請看下圖：

我敢肯定有一些簡單的我已經錯過了，但不能把我的手指上。

編輯：好吧我張貼完整的代碼。我有一個用戶控制，OddsRow，看起來像這樣：

<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="30*"></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="Win" /> 
      <ComboBoxItem Content="Place" /> 
      <ComboBoxItem Content="Lose" /> 
     </ComboBox> 
    </Grid> 
</UserControl> 

而且它顯示在的MainPage像這樣：

分別組合框的作品，也是代號爲OddsRow作品如預期......分開。合併後不顯示這些項目。

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 + " - "; 
     } 
    } 
}

一切的愛，請不要使用股票組合框。使用類似ListPicker的東西。它將使您的應用程序看起來與Metro UI更加一致。
