WPF:ListView 分组合并

• CollectionViewSource 绑定的是从数据库取出的数据ListBind
• 以DeptName为分组依据

•     <Window.Resources>
          <CollectionViewSource x:Key="Data"  Source="{Binding ListBind}">
              <CollectionViewSource.GroupDescriptions>
                  <PropertyGroupDescription PropertyName="DeptName"/>
              </CollectionViewSource.GroupDescriptions>
          </CollectionViewSource>
      </Window.Resources>

• 以DeptName为分组依据，扩展列头显示科室名称DeptName，
• TextBlock绑定的数据为DeptName的Name,而不是 Text="{Binding Path=DeptName}"

• <ListView Name="list_Reg"  ItemsSource="{Binding Source={StaticResource Data}}" Style="{StaticResource ListViewStyle}">
                  <!--分组合并style-->
                  <ListView.GroupStyle>
                      <GroupStyle>
                          <GroupStyle.ContainerStyle>
                              <Style TargetType="{x:Type GroupItem}">
                                  <Setter Property="Margin" Value="0,0,0,5"/>
                                  <Setter Property="Template">
                                      <Setter.Value>
                                          <ControlTemplate TargetType="{x:Type GroupItem}">
                                              <Expander IsExpanded="True" BorderBrush="#FF1975A0" BorderThickness="2">
                                                  <Expander.Header>
                                                      <DockPanel>
                                                          <TextBlock FontWeight="Bold" Text="{Binding Path=Name}" 
                                                                 Margin="5,0,0,0" Width="auto"/>
