这些是我的课程:
class mainViewModel
{
public List<Foo> F { get; set; }
public mainViewModel()
{
F=new List<Foo>()
{
new Foo(new Animal(){Name = "Cat"}),
new Foo(new Animal(){Name = "Dog"}),
new Foo(new Animal(){Name = "Camel"})
};
}
}
public class Foo
{
public Animal Animal { get; set; }
public Foo(Animal animal)
{
Animal = animal;
}
}
public class Animal
{
public string Name { get; set; }
}
这是我的MainWindow Xaml代码:
<TabControl ItemsSource="{Binding Path=F}">
<TabControl.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Animal.Name}"/>
</DataTemplate>
</TabControl.ItemTemplate>
<TabControl.ContentTemplate>
<DataTemplate>
<TextBlock Text="Something 1"/>
</DataTemplate>
</TabControl.ContentTemplate>
</TabControl>
现在很明显,我会为列表TabControl
中的每个项目设置F
一个页面,所有TabControl
页面都有TextBlock
Something 1 < / em>如下所示:
我想要的只是设计其中一个页面。比如将新的button
添加到名为 Something 3 的Camel页面。

根据上述评论:
为每个标签创建一个特定的ViewModel类:
public class Tab1: ViewModelBase
{
//... functionality, properties, etc
}
public class Tab2: ViewModelBase
{
//... functionality, properties, etc
}
public class Tab3: ViewModelBase
{
//... functionality, properties, etc
}
然后为每个创建一个特定的视图(通常以UserControls的形式):
<UserControl x:Class"UserControl1" ...>
<!-- UI Elements, etc -->
</UserControl>
<UserControl x:Class"UserControl2" ...>
<!-- UI Elements, etc -->
</UserControl>
<UserControl x:Class"UserControl3" ...>
<!-- UI Elements, etc -->
</UserControl>
然后为每个ViewModel类型创建DataTemplates
并将这些UserControls
放入其中:
修改:这些内容应在App.xaml
Application.Resources
下的<Application ....>
<Application.Resources>
<DataTemplate DataType="{x:Type local:ViewModel1}">
<local:UserControl1/>
</DataTemplate>
<DataTemplate DataType="{x:Type local:ViewModel2}">
<local:UserControl2/>
</DataTemplate>
<DataTemplate DataType="{x:Type local:ViewModel3}">
<local:UserControl2/>
</DataTemplate>
</Application.Resources>
</Application>
中定义:
ObservableCollection<ViewModelBase>
最后,在主ViewModel中添加public ObservableCollection<ViewModelBase> Tabs {get;set;} //Representing each Tab Item
public MainViewModel() //Constructor
{
Tabs = new ObservableCollection<ViewModelBase>();
Tabs.Add(new ViewModel1());
Tabs.Add(new ViewModel2());
Tabs.Add(new ViewModel2());
}
并添加以下项目:
{{1}}
