通过Demo学WPF—数据绑定（二）

准备

今天学习的Demo是Data <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />Binding中的Linq：

创建一个空白解决方案，然后添加现有项目，选择Linq，解决方案如下所示：

查看这个Demo的效果：

开始学习这个Demo

xaml部分

查看MainWindow.xaml：

</Window.Resources> <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />是 <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />XAML <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />中的一个元素，它定义了一个资源字典，你可以在其中声明和存储可在整个窗口中重用的资源。
我们发现包含两个资源：一个 <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />Tasks <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />对象和一个 <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />DataTemplate。
通过上一篇文章的学习，我们明白
的意思就是创建了一个 <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />Tasks <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />对象，并给它分配了一个键（key）MyTodoList。这样你就可以在其他地方通过这个键引用这个 <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />Tasks <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />对象了。
DataTemplate又是什么呢？

表示以下这部分：


我们会发现它没有显式的写 <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />，而且它的ListBoxItem数量不是固定的。
它使用了ItemsSource="{Binding}"，ItemsSource <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />是 <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />ListBox <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />的一个属性，它决定了 <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />ListBox <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />中显示的项的数据源。
{Binding} <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />是一个标记扩展，它创建一个数据绑定。在这个例子中，由于没有指定路径（Path），所以它会绑定到当前的数据上下文（DataContext）。数据上下文通常在父元素中设置，并且所有的子元素都可以访问。
<TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />ItemTemplate="{StaticResource <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />MyTaskTemplate}"表示每个对象将按照这个模板进行显示。

实现INotifyPropertyChanged接口的主要目的是为了提供一个通知机制，当对象的一个属性更改时，可以通知到所有绑定到该属性的元素。
INotifyPropertyChanged <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />接口只有一个事件 <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />PropertyChanged。当你的类实现了这个接口，你需要在每个属性的 <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />setter <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />中触发这个事件。这样，当属性的值更改时，所有绑定到这个属性的 <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />UI <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />元素都会收到通知，并自动更新其显示的值。

ObservableCollection <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />是 <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />.NET <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />框架中的一个类，它表示一个动态数据集合，当添加、删除项或者整个列表刷新时，它会提供通知。这对于绑定到 <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />UI <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />元素（例如 <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />WPF <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />或 <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />UWP <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />应用程序中的数据绑定）非常有用，因为当集合更改时，UI <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />元素可以自动更新。

过程

首先实例化了一个Tasks类如下：

包含这些Task类。
以选择“2”为例，进行说明：

打个断点：

DataContext的结果如下：

中的ItemsSource="{Binding}"表示ListBox的数据源就是DataContext，也就是有3个Task对象，也就是有3个ListItem，每个ListItem都按照{StaticResource <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />MyTaskTemplate}这个模板进行显示。
结果就如上图所示。
测试

最后为了测试自己是否真的理解，可以按照自己的意图进行更改，比如我想根据工作类型进行数据的显示。
修改数据模板。
<TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" /> <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" /> <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" /> <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />Home <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" /> <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" /> <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" /> <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=TaskName}" />Work修改第一个ListBox。
