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。
