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。
