How can I sort a DataGridTemplateColumn on a WPF Toolkit DataGrid?
提问by Kilhoffer
I have a WPF Toolkit DataGrid with one DataGridTemplateColumn. I've specified in a grid attribute that I wish all columns to be sortable, but the DataGridTemplateColumn won't allow it. All other columns do allow sorting. I've even tried explicitly setting CanUserSort to true for that column, but no luck. Is it even possible to sort a template column? I've provided a custom sorter that works for all columns, but the header won't allow a sort click.
我有一个带有一个 DataGridTemplateColumn 的 WPF Toolkit DataGrid。我在 grid 属性中指定了我希望所有列都可以排序，但 DataGridTemplateColumn 不允许。所有其他列都允许排序。我什至尝试将该列的 CanUserSort 显式设置为 true，但没有运气。甚至可以对模板列进行排序吗？我提供了一个适用于所有列的自定义排序器，但标题不允许单击排序。
<Controls:DataGrid ItemsSource="{Binding Events}" AutoGenerateColumns="False"
CanUserSortColumns="True"
CanUserReorderColumns="False"
Sorting="DataGrid_Sorting"
x:Name="EventsGrid">
<Controls:DataGrid.Columns>
<Controls:DataGridTemplateColumn Header="Type" Width="42" CanUserResize="False">
<Controls:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Image Source="{Binding EventTypeImage, Mode=OneWay}" HorizontalAlignment="Center" Width="16"/>
</DataTemplate>
</Controls:DataGridTemplateColumn.CellTemplate>
</Controls:DataGridTemplateColumn>
<Controls:DataGridTextColumn Header="Source"
Binding="{Binding Source, Mode=OneWay}" />
<Controls:DataGridTextColumn Header="Details" MinWidth="175"
Binding="{Binding Details, Mode=OneWay}" />
<Controls:DataGridTextColumn Header="Timestamp" MinWidth="175"
Binding="{Binding Timestamp, Mode=OneWay}"
IsReadOnly="True"/>
</Controls:DataGrid.Columns>
</Controls:DataGrid>

You need to set the SortMemberPathproperty on Controls:DataGridTemplateColumnto the name of the CLR property you want to sort on.
您需要将SortMemberPath属性设置为Controls:DataGridTemplateColumn要排序的 CLR 属性的名称。

Added SortMemberPath="Name"to DataGridTemplateColumn. It started sorting.
添加SortMemberPath="Name"到 DataGridTemplateColumn。它开始排序。
<data:DataGridTemplateColumn Header="Name" SortMemberPath="Name" CanUserSort="True">

<DataGridTemplateColumn SortMemberPath="DataDiNascita" Header="Data di nascita" IsReadOnly="True">
<DataGridTemplateColumn.CellEditingTemplate>
<DataTemplate>
<DatePicker SelectedDate="{Binding Path=DataDiNascita}"></DatePicker>
</DataTemplate>
</DataGridTemplateColumn.CellEditingTemplate>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=DataDiNascita,StringFormat=\{0:dd/MM/yyyy\}}"></TextBlock>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
