WPF:ListView 分组合并-优快云博客

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"/>

</DockPanel> </Expander.Header> <Expander.Content> <ItemsPresenter/> </Expander.Content> </Expander> </ControlTemplate> </Setter.Value> </Setter> </Style> </GroupStyle.ContainerStyle> </GroupStyle> </ListView.GroupStyle>

后来看到xml的分组
