[英]Two column data binding in a listbox trouble
My understanding of DataBinding is still at the "working on it" level, so here is my issue. 我对DataBinding的理解仍处于“正在研究中”的水平,所以这是我的问题。 I have this data:
我有此数据:
private class User
{
public string username { get; set; }
public string real_name { get; set; }
}
ObservableCollection<User> users = new ObservableCollection<User>();
...adds stuff...
CollectionView view = (CollectionView)CollectionViewSource.GetDefaultView(users);
I want this to be displayed in a two column ListBox. 我希望将其显示在两列ListBox中。 I've gotten in in a two column ComboBox by doing:
我通过执行以下操作进入了两列ComboBox:
<ComboBox Height="23" HorizontalAlignment="Left" Margin="114,23,0,0" Name="comboBox_client" VerticalAlignment="Top" Width="113" IsEditable="True" ItemsSource="{Binding}" >
<ComboBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding username}" Name="left" Width="50" />
<TextBlock Text="{Binding real_name}" Name="right" Width="100" />
</StackPanel>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
with 同
comboBox_client.ItemsSource = view;
But I'm not sure how to make the step over to a ListBox, since I see no ItemTemplate, and I don't understand the concept behind what the above Xaml is actually doing. 但是我不确定如何过渡到ListBox,因为我没有看到ItemTemplate,而且我不理解上述Xaml实际上在做什么的概念。 If I take out the ItemTemplate part and try the rest on the ListBox, I just just a listbox full of System.Windows.DataTemplate.
如果我取出ItemTemplate部分并尝试在ListBox上进行其余操作,那么我只是一个充满System.Windows.DataTemplate的列表框。
Point in the right direction please? 请指向正确的方向?
ListBox has an ItemTemplate
property too. ListBox也具有
ItemTemplate
属性。 I think you just missed that. 我想你只是想念那个。
You can just use the same DataTemplate
you used for your ComboBox
. 您可以只使用与
ComboBox
相同的DataTemplate
。
ListBox: 列表框:
<ListBox ItemsSource="{Binding}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding username}" Width="50" />
<TextBlock Text="{Binding real_name}" Width="100" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
But it seems to me, ListView is more suitable for this task: 但在我看来,ListView更适合此任务:
<ListView ItemsSource="{Binding}">
<ListView.View>
<GridView>
<GridViewColumn Header="User name" DisplayMemberBinding="{Binding username}" Width="50" />
<GridViewColumn Header="Name" DisplayMemberBinding="{Binding RealName}" Width="100" />
</GridView>
</ListView.View>
</ListView>
