如何在XAML中說.ToString（）？

Question

下面的代碼給了我錯誤（不能將類型Object添加到Stackpanel）。

如何在XAML中說.ToString（）？

<Window.Resources> 
    <Style TargetType="{x:Type ListBoxItem}"> 
     <Setter Property="Content"> 
      <Setter.Value> 
       <StackPanel Orientation="Horizontal"> 
        <TextBlock Text="{Binding Path=FirstName}"/> 
       </StackPanel> 
      </Setter.Value> 
     </Setter> 
    </Style> 
</Window.Resources> 
<Grid> 
    <ListBox x:Name="theCustomers"/> 
</Grid> 

與ADO.NET實體框架綁定後臺代碼：

MainEntities db = new MainEntities(); 
var customers = from c in db.CustomersSet 
       select c; 
theCustomers.ItemsSource = customers;

您需要設置該屬性ContentTemplate，不Content。

嘗試：

<Setter Property="ContentTemplate" > 
    <Setter.Value> 
     <DataTemplate> 
     <StackPanel Orientation="Horizontal"> 
      <TextBlock Text="{Binding Path=FirstName}"/> 
      <TextBlock Text=" "/> 
      <TextBlock Text="{Binding Path=LastName}"/> 
     </StackPanel> 
     </DataTemplate> 
    </Setter.Value> 
</Setter>
