在运行时添加复合WPF区域

     <TabControl cal:RegionManager.RegionName="TabRegion" x:Name="tabDemo" ItemsSource="{Binding Something}" >
        <TabControl.ItemTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding}" />
            </DataTemplate>
        </TabControl.ItemTemplate>
     </TabControl>

Prism中的StockChartsRI显示了如何从视图模型中绑定选项卡的标题。它们使用TabPanel的子类(AnimatedTabPanel),但设置是相同的。

基本上,当使用数据绑定生成tabItems时,我在代码中设置了所有区域内容。

  private void AddDynamicRegion(object arg)
  {
     var newRegionName = "Region" + (DynamicRegions.Count + 1).ToString();
     DynamicRegions.Add(newRegionName);

     var tabItem = View.tabDemo.ItemContainerGenerator.ContainerFromIndex(DynamicRegions.Count - 1) as TabItem;
     var newRegionContainer = new ItemsControl();
     RegionManager.SetRegionName(newRegionContainer,newRegionName);
     RegionManager.SetRegionManager(newRegionContainer, _regionManager);
     tabItem.Content = newRegionContainer;


  }

  private void AddRandomRegionContent(object arg)
  {

     if (string.IsNullOrEmpty(SelectedRegion) )
        return; 

     Debug.WriteLine("Injected "  + RegionContent + " into " + SelectedRegion);

     var newContent = new TextBlock() { Text = RegionContent };
     var region = _regionManager.Regions[SelectedRegion];
     if (region == null)
     {
        Debug.WriteLine("Couldn't find region");
        return;
     }

     region.Add(newContent);
     region.Activate(newContent);

  }
