在.cs文件中使用silverlight的自定义Tabcontrol？ 在自定义tabitem标头中添加堆栈面板不起作用

如何解决在.cs文件中使用silverlight的自定义Tabcontrol？ 在自定义tabitem标头中添加堆栈面板不起作用

| 在Silverlight Tab控件中，我使用xaml完美地添加了自定义标签页眉（名称和关闭按钮）。 {xaml代码}

<Grid Height=\"559\" Name=\"grid1\" Width=\"953\">
<sdk:TabControl Height=\"391\" HorizontalAlignment=\"Left\" Margin=\"105,57,0\" 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\" VerticalAlignment=\"Center\" />
                <Button Content=\"X\" />
            </StackPanel>
        </sdk:TabItem.Header>
        <Grid />
    </sdk:TabItem>
</sdk:TabControl>
<Button Content=\"+\" Height=\"23\" HorizontalAlignment=\"Left\" Margin=\"74,0\" Name=\"button1\" VerticalAlignment=\"Top\" Width=\"31\" Click=\"button1_Click\" />
<Button Content=\"-\" Height=\"23\" HorizontalAlignment=\"Left\" Margin=\"12,492,0\" Name=\"button2\" VerticalAlignment=\"Top\" Width=\"31\" Click=\"button2_Click\" Visibility=\"Collapsed\" />

相同的实现尝试使用.cs，但是我可以在新标签页眉内添加堆栈面板 代码供您参考

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

             tabControl1.Items.Add(new TabItem
            {
                Header =st              

            });

帮我解决这个问题。我需要带有按钮控件的“自定义”标签页眉     

解决方法

        您应该设置

tbItem.Header = st

。 tbItem.Content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);
  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：这是一个完整的示例 使用TabControl的XAML-注意，我钩住了Loaded事件，在这里将添加动态TabItem。

<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>

这是背后的代码

using System;
using System.Windows;
using System.Windows.Controls;

namespace SilverlightApplication1
{
  public partial class MainPage : UserControl
  {
    public MainPage()
    {
      InitializeComponent();
    }

    private void TabControl_Loaded(object sender,RoutedEventArgs e)
    {
      StackPanel st = new StackPanel();
      st.Orientation = Orientation.Horizontal;
      TextBlock txtb = new TextBlock();
      txtb.Text = \"New Tab\";
      txtb.Margin = new Thickness(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);
    }
  }
}
