如何使列表视图与数据绑定一起使用？ [英] How do I make List View work with data binding?

问题描述

伙计们

我已经设法在Xaml中进行数据绑定但不完全。

我有文本块和数据绑定工作。我在Windows应用程序中将信息从第2页传递到第3页。

我的列表视图完全相同，但根本不起作用。我不明白为什么。有人可以看看吗？

Hi, guys
I've managed to do Data Binding in Xaml but not completely.
I have got text block and Data Binding works. I'm passing information from page 2 to page3 in my windows app.
I have done exactly the same with my List View and it doesn't work at all. I don't understand why. Can someone please have a look?

<ListView Name="detailsListView" Grid.Row="1" Height="300" Width="400" 

ItemsSource="{Binding Name}"/>

        <TextBlock Text="{Binding Name}" x:Name="myTextBlock" Grid.Row="1" Grid.Column="2" Height="200" Width="300" FontSize="28"/>

在我的代码背后数据上下文设置为页面布局

In my Code Behind The data context is set to the page layout

protected override void OnNavigatedTo(NavigationEventArgs e)
{
    Nutrient nutriQuery = e.Parameter as Nutrient;
    if (nutriQuery != null)
    {
        DetailsPageLayout.DataContext = nutriQuery;
    }

为什么文本块可以工作而不是列表视图？

Why Text Block works but not List View?

推荐答案

您需要将ItemsSource绑定到ObservableCollection。您还需要定义ListView视图。这样的事情。

You need to bind the ItemsSource to an ObservableCollection. You also need to define the ListView View. Something like this.

<!--In the view model, PersonCollection is a collection of type Person
SelectedPerson is a property of type Person.Name and Age are  properties defined     inside the Person class-->
           <listview itemssource="{Binding PersonCollection}" selecteditem="{Binding SelectedPerson, Mode=TwoWay}" issynchronizedwithcurrentitem="True">
               HorizontalAlignment="Center" Height="168"  VerticalAlignment="Top" Width="400" Background="#FFBFBFBF">
               <listview.view>
                   <gridview>
                       <gridviewcolumn width="280" header="Name" displaymemberbinding="{Binding Path=Name}" />
                       <gridviewcolumn width="60" header="Age" displaymemberbinding="{Binding Path=Age}" />
                   </gridview>
               </listview.view>
           </listview>
