您可以使用DataTrigger来切换ContentTemplate,如下所示。
请注意,我将ObservableCollection绑定到一个简单对象(Thing),该对象具有一个名为Name的属性,并使用ViewModel将ContentControl的内容绑定到ListBox中的SelectedItem。
<Grid>
<Grid.Resources>
<local:MultiValueConverter x:Key="con" />
<DataTemplate x:Key="PeopleTemplate">
<StackPanel Orientation="Horizontal">
<Label Margin="0,0,5,0" Content="People Name" HorizontalAlignment="Left" Grid.Column="0" />
<TextBox Grid.Column="1" Width="100" Height="25"></TextBox>
<Button Content="OK" Grid.Column="2" />
</StackPanel>
</DataTemplate>
<DataTemplate x:Key="AnimalsTemplate">
<StackPanel Orientation="Horizontal">
<Label Margin="0,0,5,0" Content="Animal Name" HorizontalAlignment="Left" Grid.Column="0" />
<TextBox Grid.Column="1" Width="100" Height="25"></TextBox>
<Button Content="OK" Grid.Column="2" />
</StackPanel>
</DataTemplate>
<DataTemplate x:Key="CarsTemplate">
<StackPanel Orientation="Horizontal">
<Label Margin="0,0,5,0" Content="Car Name" HorizontalAlignment="Left" Grid.Column="0" />
<TextBox Grid.Column="1" Width="100" Height="25"></TextBox>
<Button Content="OK" Grid.Column="2" />
</StackPanel>
</DataTemplate>
</Grid.Resources>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<StackPanel Grid.Row="0" Orientation="Horizontal">
<ListBox ItemsSource="" SelectedItem="">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Margin="0" Orientation="Horizontal">
<TextBlock Padding="5" Text="" Margin="0"></TextBlock>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<Border Width="200">
<ContentControl Content="">
<ContentControl.ContentTemplate>
<DataTemplate>
<ContentControl Name="cc"
Content=""
ContentTemplate="" />
<DataTemplate.Triggers>
<DataTrigger Binding="" Value="People">
<Setter TargetName="cc"
Property="ContentTemplate"
Value="" />
</DataTrigger>
<DataTrigger Binding="" Value="Animals">
<Setter TargetName="cc"
Property="ContentTemplate"
Value="" />
</DataTrigger>
<DataTrigger Binding="" Value="Cars">
<Setter TargetName="cc"
Property="ContentTemplate"
Value="" />
</DataTrigger>
</DataTemplate.Triggers>
</DataTemplate>
</ContentControl.ContentTemplate>
</ContentControl>
</Border>
</StackPanel>
<Grid>
这里是Thing类:
public class Thing
{
public Thing(String name)
{
this.Name = name;
}
public String Name { get; set; }
public static ObservableCollection<Thing> GetThingList()
{
return new ObservableCollection<Thing>(new Thing[3] {
new Thing("People"),
new Thing("Animals"),
new Thing("Cars")
});
}
}
