WPF绑定各种数据源之object数据源

一、WPF绑定各种数据源索引

WPF 绑定各种数据源之Datatable

WPF绑定各种数据源之object数据源

WPF绑定各种数据源之xml数据源

WPF绑定各种数据源之元素控件属性

Binding的基础可参考WPF 绑定基础

 

二、WPF绑定各种数据源之object数据源

前台代码：

  <Window.Resources>
        <Con:BackgroundConverter x:Key="BackgroundConverter"/>
    </Window.Resources>

　　用ListView绑定object数据源

  <ListView Height="262" Margin="0,0,45,51" VerticalAlignment="Bottom" ItemsSource="{Binding}" Name="listView2" HorizontalAlignment="Right" Width="310">
            <ListView.View>
                <GridView>
                    <GridViewColumn Header="编号" DisplayMemberBinding="{Binding Path=ID}"  Width="100" />
                    <GridViewColumn Header="姓名" DisplayMemberBinding="{Binding Path=Name}" Width="100"/>
                    <GridViewColumn Header="年龄" Width="100">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Grid.Column="1" Text="{Binding Path=Age}" Foreground="{Binding Path=Age, Converter={StaticResource BackgroundConverter}}"/>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                </GridView>
            </ListView.View>
        </ListView>

　　

后台代码：

 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
    }

　　下面是Person类

 public class Person
    {
        private string _ID;
        private string _name;
        private string _age;
        public string ID
        {
            get;
            set;
        }
        public string Name
        {
            get;
            set;
        }
        public int Age
        {
            get;
            set;
        }
    }

　　//下面是获得数据源，当然数据源可以是数据库中读出的数据，此处直接创建数据源

       //创建数据源，当然也可以从数据库中获得数据源
      private IList<Person> getPersonInfo()
        {
            IList<Person> pList = new List<Person>();
            for (int i = 40; i < 60; i++)
            {
                Person p = new Person();
                p.ID = "ID"+i;
                p.Name =  "Nmae"+i;
                p.Age = i+1;
                pList.Add(p);
            }
            return pList;
        }

      public Window1()
       {
            InitializeComponent();
            listView2.DataContext = getPersonInfo();
        }

　　效果图：

 2. 使用Object的另一种方式

    <Window.Resources>
        <Con:BackgroundConverter x:Key="BackgroundConverter"/>
        <ObjectDataProvider x:Key="myPerson" ObjectType="{x:Type Con:Person}"  MethodName="getPersonInfo"/>
    </Window.Resources>

　此时的myPerson对象数据源在是Person类中的getPersonInfo方法。

　（【补充】如果getPersonInfo在不同的类库中，则用如下方式

   <ObjectDataProvider x:Key="myPerson2" ObjectType="{x:Type ClassLibrary1:Person}"  MethodName="getPersonInfo"/>

　　使用，ClassLibrary1是类库的名称。并添加命名空间

 xmlns:ClassLibrary1="clr-namespace:ClassLibrary1;assembly=ClassLibrary1"

　　） 

 <ListView Height="262" Margin="0,0,45,51" DataContext="{StaticResource myPerson}" VerticalAlignment="Bottom" ItemsSource="{Binding}" Name="listView2" HorizontalAlignment="Right" Width="310">
            <ListView.View>
                <GridView>
                    <GridViewColumn Header="编号" DisplayMemberBinding="{Binding Path=ID}"  Width="100" />
                    <GridViewColumn Header="姓名" DisplayMemberBinding="{Binding Path=Name}" Width="100"/>
                    <GridViewColumn Header="年龄" Width="100">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Grid.Column="1" Text="{Binding Path=Age}" Foreground="{Binding Path=Age, Converter={StaticResource BackgroundConverter}}"/>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                </GridView>
            </ListView.View>
        </ListView>
