在WPF中的窗口数据文本中进行排序 [英] Sorting in window datacontext in WPF

问题描述

与这一个有关的另一个问题。

Another question related to this one.

我有一个列表< SortableObjects> 即 DataContext 我的MainWindow。我使用该列表来填充一个 ListBox 和一个 ComboBox 。当我对项目进行排序时，$ code> ComboBox 和 ListView 将被更新。但现在我需要以 ListView 不同的方式对 ComboBox 进行排序。 IE如果对象是一个Person，在 ComboBox 中，我需要使用LastName对它们进行排序，但在 ListView ，生日。如何实现这一点？

I have a List<SortableObjects> that is the DataContext of my MainWindow. I use that list to populate a ListBox and a ComboBox. When I sort the items, both the ComboBox and the ListView get updated all right. But now I need the ComboBox to be sorted in a different way than the ListView. I. E. If the object were a Person, in the ComboBox, I'd need to sort them by LastName, but in the ListView, by birthday. How can I achieve this?

谢谢！

推荐答案

a href =http://msdn.microsoft.com/en-us/library/system.windows.data.collectionviewsource.aspx =nofollow noreferrer> CollectionViewSource ，您需要的每个单独订单：

Use CollectionViewSources for each of the separate orderings you want:

<UserControl.Resources>
    <CollectionViewSource x:Key="ComboBoxSource" Source="{Binding YourUnderlyingCollection}">
        <CollectionViewSource.SortDescriptions>
            <scm:SortDescription PropertyName="SomeProperty"/>
        </CollectionViewSource.SortDescriptions>
    </CollectionViewSource>

    <CollectionViewSource x:Key="ListBoxSource" Source="{Binding YourUnderlyingCollection}">
        <CollectionViewSource.SortDescriptions>
            <scm:SortDescription PropertyName="SomeOtherProperty"/>
        </CollectionViewSource.SortDescriptions>
    </CollectionViewSource>
</UserControl.Resources>

<ComboBox ItemsSource="{Binding Source={StaticResource ComboBoxSource}}"/>

<ListBox ItemsSource="{Binding Source={StaticResource ListBoxSource}}"/>
