How to Sort a DataGridTextColumn which uses a MultiBinding Converter
提问by Steztric
I use a multibinding with a value converter to provide the visual display of a collection of items in my DataContext. Here is a snippet of the XAML;
我使用带有值转换器的多重绑定来提供我的DataContext. 这是 XAML 的一个片段；
<DataGrid.Columns>
<DataGridTextColumn x:Name="Column1"
SortMemberPath="{Binding Path=SomeDataModelProperty}">
<DataGridTextColumn.Binding>
<MultiBinding Converter="{StaticResource MyCustomConverter}">
<Binding Path="SomeDataModelProperty" />
<Binding RelativeSource="{RelativeSource Self}" Path="ActualWidth" />
<!-- Other bindings -->
</MultiBinding>
</DataGridTextColumn.Binding>
</DataGridTextColumn>
The binding on the SortMemberPathis such that I can sort by the property in my DataContext. However, I get an error on the output window
上的绑定SortMemberPath使得我可以按我的DataContext. 但是，我在输出窗口上收到错误消息
Cannot find governing FrameworkElement or FrameworkContentElement for target element.
Googling this issue yields a result using DXGrid by DevExpress, but not one using the standard WPF data grid. Does anyone know the correct way to provide the sorting to the data grid column?
谷歌搜索这个问题会产生一个使用DevExpress 的 DXGrid的结果，但不是使用标准 WPF 数据网格的结果。有谁知道为数据网格列提供排序的正确方法？

I figured it out, thanks to this article. In the end it is quite simple;
我想通了，多亏了这篇文章。最后它很简单；
<DataGridTextColumn x:Name="Column1"
SortMemberPath="SomeDataModelProperty">
i.e. don't use a binding, just specify the property name directly.
即不使用绑定，只需直接指定属性名称。
