WPF 多个数据源的实现DEMO

WPF 多个数据源的实现DEMO，ListView中有个Combox籍贯，ListView的数据来自XML数据源，Combox籍贯来自另一个数据源。

     <ListView Height="262" Margin="345,12,12,0" ItemsSource="{Binding Source={StaticResource myPerson4},XPath=/PersonF/person}" VerticalAlignment="Top"  Name="listView3">

            <ListView.Resources>

                <Con:JiGuan x:Key="JG"/>

            </ListView.Resources>

            <ListView.View>

                <GridView>

                    <GridViewColumn Header="编号" DisplayMemberBinding="{Binding XPath=ID}"  Width="100" />

                    <GridViewColumn Header="姓名" DisplayMemberBinding="{Binding XPath=Name}" Width="100"/>

                    <GridViewColumn Header="年龄" Width="100">

                        <GridViewColumn.CellTemplate>

                            <DataTemplate>

                                <TextBlock Grid.Column="1" Text="{Binding XPath=Age}" Foreground="{Binding XPath=Age, Converter={StaticResource BackgroundConverter}}"/>

                            </DataTemplate>

                        </GridViewColumn.CellTemplate>

                    </GridViewColumn>

                    <GridViewColumn Header="籍贯"  Width="100">

                        <GridViewColumn.CellTemplate>

                            <DataTemplate>

                                <ComboBox  DataContext="{Binding Source={StaticResource JG}}" Width="50"  SelectedIndex="0">

                                    <ItemsControl ItemsSource="{Binding JGuan}">

                                        <ItemsControl.ItemTemplate>

                                            <DataTemplate>

                                                <TextBlock Text="{Binding}"/>

                                            </DataTemplate>

                                        </ItemsControl.ItemTemplate>

                                    </ItemsControl>

                                </ComboBox>

                            </DataTemplate>

                        </GridViewColumn.CellTemplate>

                    </GridViewColumn>

                </GridView>

            </ListView.View>

        </ListView>

资源：

 <Window.Resources>

        <Con:BackgroundConverter x:Key="BackgroundConverter"/>

         <XmlDataProvider x:Key="myPerson4" Source="/Person.xml"/>

    </Window.Resources>

值转换：

   public class BackgroundConverter : IValueConverter

    {

        #region IValueConverter Members



        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

        {

            Color color = new Color();

            int num = int.Parse(value.ToString());

            if (num > 100)

                color = Colors.Yellow;

            else if (num < 50)

                color = Colors.LightGreen;

            else

                color = Colors.LightPink;

            return new SolidColorBrush(color);

        }



        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

        {

            throw new NotImplementedException();

        }



        #endregion

    }

籍贯类：　　

    public class JiGuan

    {

        private ObservableCollection<string> _jiguan;

        public JiGuan()

        {

            _jiguan = new ObservableCollection<string>();

            _jiguan.Add("上海");

            _jiguan.Add("杭州");

            _jiguan.Add("南京");

            _jiguan.Add("广州");

        }



        public ObservableCollection<string> JGuan

        {

            get { return new ObservableCollection<string>(_jiguan); }

            private set { }

        }



    }

　　

XML文件

<?xml version="1.0" encoding="utf-8" ?>

<PersonF xmlns="">

  <person Name="Person1">

    <ID>1</ID>

    <Name>XiaoA</Name>

    <Age>59</Age>

  </person>

  <person Name="Person2">

    <ID>2</ID>

    <Name>XiaoB</Name>

    <Age>29</Age>

  </person>

  <person Name="Person3">

    <ID>3</ID>

    <Name>XiaoC</Name>

    <Age>103</Age>

  </person>

  <person Name="Person4">

    <ID>4</ID>

    <Name>XiaoD</Name>

    <Age>59</Age>

  </person>

</PersonF>

　　效果图：如下图，编号，姓名，年龄，籍贯来自不同的数据源，但是却在同一个ListView中，编号，姓名，年龄来自XML数据，籍贯来自籍贯类。
