ListView 的三种数据绑定方式

1.最原始的绑定方式：

 

  public ObservableCollection<object> ObservableObj;
        public MainWindow()
        {
            InitializeComponent();
            ObservableObj = new ObservableCollection<object>();
            ObservableObj.Add(new { Name = "帅波", Sex = "男", Age = 20 });
            ObservableObj.Add(new { Name = "帅波2", Sex = "女", Age = 60 });
            ObservableObj.Add(new { Name = "帅波3", Sex = "女", Age = 50 });
            ObservableObj.Add(new { Name = "帅波4", Sex = "女", Age = 40 });
            ObservableObj.Add(new { Name = "帅波5", Sex = "男", Age = 20 });
            lv.DataContext = ObservableObj;
         }

 

当然了，用list<object> 也可以，只不过数据源变化后，要调用lv.Items.Refresh();

前台如下：

 

   <ListView Height="122" HorizontalAlignment="Left"   ItemsSource="{Binding}" Margin="33,67,0,0" Name="lv" VerticalAlignment="Top" Width="400" >
            <ListView.View>
                <GridView  >
                    <GridViewColumn DisplayMemberBinding="{Binding Path=Name}" Width="50" Header="姓名"  />
                    <GridViewColumn DisplayMemberBinding="{Binding Path=Sex}" Width="50" Header="性别" />
                    <GridViewColumn DisplayMemberBinding="{Binding Path=Age}" Width="50" Header="年龄"   >
                        <GridViewColumn.HeaderTemplate>
                            <DataTemplate>
                                <TextBlock  Text="{Binding}"  Foreground="Red"/>
                            </DataTemplate>
                        </GridViewColumn.HeaderTemplate>
                    </GridViewColumn>
                </GridView>
            </ListView.View>
        </ListView>

2.用xml绑定

 

 <XmlDataProvider x:Key="xmlData"  XPath="/Root">
            <x:XData>
                <Root xmlns="">
                    <Item Name="刷波波10"  Sex="女" Age="11"/>
                    <Item Name="刷波波11"  Sex="男" Age="11"/>
                    <Item Name="刷波波12"  Sex="女" Age="11"/>
                    <Item Name="刷波波13"  Sex="女" Age="11"/>
                    <Item Name="刷波波14"  Sex="男" Age="11"/>
                </Root>
            </x:XData>
        </XmlDataProvider>

        <CollectionViewSource x:Key="viewSource" Source="{Binding Source={StaticResource xmlData},XPath=Item}">
            <CollectionViewSource.GroupDescriptions>
                <PropertyGroupDescription PropertyName="@Sex" />
            </CollectionViewSource.GroupDescriptions>
        </CollectionViewSource>

listView的每一列绑定，需要加上@符号，Psath也换成XPath

 

 <ListView Height="122" HorizontalAlignment="Left" ItemsSource="{Binding Source={StaticResource viewSource}}" 
                  Margin="475,67,0,0" Name="lv2" VerticalAlignment="Top" Width="400">
            <ListView.GroupStyle>
                <GroupStyle>
                    <GroupStyle.ContainerStyle>
                        <Style TargetType="{x:Type GroupItem}">
                            <Setter Property="Template" >
                                <Setter.Value>
                                    <ControlTemplate  TargetType="{x:Type GroupItem}">
                                        <Expander  BorderBrush="Silver" BorderThickness="1">
                                            <Expander.Header>
                                                <DockPanel>
                                                    <TextBlock Text="{Binding Path=Name}"  Width="100"/>
                                                    <TextBlock Text="{Binding Path=ItemCount}" />
                                                </DockPanel>
                                            </Expander.Header>
                                            <Expander.Content>
                                                <ItemsPresenter />
                                            </Expander.Content>
                                        </Expander>
                                    </ControlTemplate>
                                </Setter.Value>
                            </Setter>
                        </Style>
                    </GroupStyle.ContainerStyle>
                </GroupStyle>
            </ListView.GroupStyle>
            <ListView.View>
                <GridView>
                    <GridViewColumn DisplayMemberBinding="{Binding XPath=@Name}" Header="姓名" Width="100" />
                    <GridViewColumn DisplayMemberBinding="{Binding XPath=@Sex}" Header="性别" Width="50" />
                    <GridViewColumn DisplayMemberBinding="{Binding XPath=@Age}" Header="年龄" Width="50">
                        <GridViewColumn.HeaderTemplate>
                            <DataTemplate>
                                <TextBlock Foreground="Red" Text="{Binding}" />
                            </DataTemplate>
                        </GridViewColumn.HeaderTemplate>
                    </GridViewColumn>
                </GridView>
            </ListView.View>
        </ListView>

 

 

3.采用ObjectDataProvider绑定

cs代码如下：

 

 public class DataProvider
    {
        public ObservableCollection<object> GetData(int limit)
        {
            ObservableCollection<object> ObservableObj = new ObservableCollection<object>();
            int i = 0;
            while (i <= limit)
            {
                ObservableObj.Add(new { Name = "帅波" + i.ToString(), Sex = "女", Age = 50 + i });
                i++;
            }

            return ObservableObj;
        }
    }

 

XAML的代码比较简单

  

 <ObjectDataProvider  x:Key="objData" MethodName="GetData" ObjectType="{x:Type local:DataProvider}">
            <ObjectDataProvider.MethodParameters>
                <sys:Int32>4</sys:Int32>
            </ObjectDataProvider.MethodParameters>
        </ObjectDataProvider>

 

最后listView的绑定如下：

 

   <ListView Height="122" HorizontalAlignment="Left" ItemsSource="{Binding Source={StaticResource objData}}" Margin="33,231,0,0" Name="lv3" VerticalAlignment="Top" Width="400">
            <ListView.View>
                <GridView>
                    <GridViewColumn DisplayMemberBinding="{Binding Path=Name}" Header="姓名" Width="50" />
                    <GridViewColumn DisplayMemberBinding="{Binding Path=Sex}" Header="性别" Width="50" />
                    <GridViewColumn DisplayMemberBinding="{Binding Path=Age}" Header="年龄" Width="50">
                        <GridViewColumn.HeaderTemplate>
                            <DataTemplate>
                                <TextBlock Foreground="Red" Text="{Binding}" />
                            </DataTemplate>
                        </GridViewColumn.HeaderTemplate>
                    </GridViewColumn>
                </GridView>
            </ListView.View>
        </ListView>

 

 

搞定。第二个，参考了网上的一个例子，具体网址忘记了。

codeproject有个经典的例子，http://www.codeproject.com/KB/WPF/ListViewDragDropManager.aspx
