一、WPF绑定各种数据源索引
Binding的基础可参考WPF 绑定基础
二、WPF绑定各种数据源之xml数据源，此时的XML源写在界面了，当然也可以独立成文件。
<Window.Resources> <Con:BackgroundConverter x:Key="BackgroundConverter"/> <XmlDataProvider x:Key="myPerson3"> <x:XData> <PersonF xmlns=""> <person Name="Person1"> <ID>1</ID> <Name>XiaoA</Name> <Age>49</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> </x:XData> </XmlDataProvider> </Window.Resources> |
下面是绑定的代码。此时需要注意，原来用Path改成了XPath，因为这是XML源，并且ItemsSource 改成 ItemsSource="{Binding Source={StaticResource myPerson3},XPath=/PersonF/person}"
<ListView Height="262" Margin="0,32,56,0" ItemsSource="{Binding Source={StaticResource myPerson3},XPath=/PersonF/person}" VerticalAlignment="Top" Name="listView3" HorizontalAlignment="Right" Width="310"> <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> </GridView> </ListView.View> </ListView> |
下面是值转换
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 } |
效果图：
2.使用外部XML数据源，只需做如下修改
<Window.Resources> <XmlDataProvider x:Key="myPerson3" Source="/Person.xml"/> </Window.Resources> |
3.如果使用外部XML数据源，并且采用C#代码的形式，则如下：
XmlDocument doc = new XmlDocument(); doc.Load(@"http://www.cnblogs.com/XMLFile1.xml"); XmlDataProvider provider = new XmlDataProvider(); provider.Document = doc; provider.XPath = @"/PersonF/person"; listView3.DataContext = provider; listView3.SetBinding(ListView.ItemsSourceProperty, new Binding()); |
当然也可以使用XMLDataProvider的Source属性，此时只需做如下修改：
XmlDataProvider provider = new XmlDataProvider();provider.Source = new Uri(@"F:\\XMLFile1.xml");provider.XPath = @"/PersonF/person"; |
其他不变。
