C# 在.cs文件中使用silverlight的自定义Tabcontrol？（在自定义tabitem标题中添加堆栈面板无效）

在Silverlight选项卡控件中，我使用xaml添加了自定义选项卡标题（名称和关闭按钮），效果非常好

{xaml代码}

<Grid Height="559" Name="grid1" Width="953">
<sdk:TabControl Height="391" HorizontalAlignment="Left" Margin="105,57,0,0" Name="tabControl1" VerticalAlignment="Top" Width="729">
    <sdk:TabItem  Name="tabItem1" IsTabStop="False">
        <sdk:TabItem.Header>
            <StackPanel Orientation="Horizontal">
                <TextBlock Text="New Tab" Margin="1,1,1,1" VerticalAlignment="Center" />
                <Button Content="X" />
            </StackPanel>
        </sdk:TabItem.Header>
        <Grid />
    </sdk:TabItem>
</sdk:TabControl>
<Button Content="+" Height="23" HorizontalAlignment="Left" Margin="74,57,0,0" Name="button1" VerticalAlignment="Top" Width="31" Click="button1_Click" />
<Button Content="-" Height="23" HorizontalAlignment="Left" Margin="12,492,0,0" Name="button2" VerticalAlignment="Top" Width="31" Click="button2_Click" Visibility="Collapsed" />

帮我解决这个问题。我需要带有按钮控件的自定义选项卡标题

您应该设置

tbItem.header=st

。内容用于定义选项卡的内容，而不是选项卡标题

您的代码看起来像这样

  StackPanel st = new StackPanel();
  st.Orientation = Orientation.Horizontal;
  TextBlock txtb = new TextBlock();
  txtb.Text = "New Tab";
  txtb.Margin = new Thickness(1, 1, 1, 1);
  txtb.VerticalAlignment = VerticalAlignment.Center;
  st.Children.Add(txtb);
  Button btn = new Button();
  btn.Content = "X";      
  st.Children.Add(btn);

  TabItem tbitem = new TabItem();
  // Set the header to the stack panel with the 
  // TextBlock and Button
  tbitem.Header = st;

  // This is where you define the content
  // of the tab page. Here I just added a Grid 
  // as an example.
  tbitem.Content = new Grid(); 

  tabControl1.Items.Add(tbitem);

编辑：下面是一个完整的示例

XAML和TabControl—注意，我钩住了加载的事件，这是我将添加动态TabItem的地方

<UserControl x:Class="SilverlightApplication1.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:controls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls"
    mc:Ignorable="d"
    d:DesignHeight="300" d:DesignWidth="400" >  
  <Grid x:Name="LayoutRoot" Background="White">
    <Grid x:Name="Container">      
      <controls:TabControl Name="tabControl1" Loaded="TabControl_Loaded">

      </controls:TabControl>
    </Grid>
  </Grid>
</UserControl>

@克里斯·泰勒：谢谢你的回复。我想在TabItem标题中添加stackpanel，而不是TabItem内容。@Ash，这就是

tbitem.header=st

所做的，它将stackpanel分配给TabItem标题，这正是XAML所做的。是否可以在TabItem中为自定义标题添加stackpanel？@Asta ni enohpi，是的，通过将StackPanel实例分配给TabItem.Header，标题将承载StackPanel。@Chris taylor:请参见我编辑的问题。但该按钮仍然不可见，选项卡的名称也显示为“新选项卡”，而不是“测试”。背后的意思是，tabitem标头不接受自定义标头。您能给出解决方案吗。我少了什么
