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>
