WPF绑定各种数据源之object数据源

来源：互联网发布：软件定制编辑：程序博客网时间：2024/04/29 21:33

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>
