TabControl

1. ItemsSource="{Binding GroupList}" SelectedItem="{Binding SelectedGroupItem,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"

ItemsSource:绑定的数据列表

SelectedItem：当前选中项

2.<TabControl.ItemTemplate>
                <DataTemplate>
                    <StackPanel>
                        <TextBlock></TextBlock>
                        <TextBlock Text="{Binding GroupName}" Tag="{Binding GroupName}" MaxWidth="80" TextTrimming="WordEllipsis"></TextBlock>
                    </StackPanel>
                </DataTemplate>
    </TabControl.ItemTemplate>

这里的意思是在TabControl的标签上，做了一个TextBlock，数据绑定的是GroupName，班级名，级“一班”，“二班”，“三班”

3.TabControl中使用了ListBox，注意事项
