我是C# WPF的新用户，并在DataGrid中自定义了C# WPF，我在下面创建了subclass： -
namespace DataGridFiltter
public class FilteringDataGrid : Microsoft.Windows.Controls.DataGrid
{
.......
}
}
并在xaml文件中我正在使用此类，如下所示： -
<UserControl x:Class="formGroup"
xmlns:dataGridFiltter="clr-namespace:DataGridFiltter">
<dataGridFiltter:FilteringDataGrid IsFilteringCaseSensitive="False" x:Name="groupTable" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" FontSize="16" AutoGenerateColumns="False" ItemsSource="{Binding DataCollection, Mode=TwoWay, NotifyOnSourceUpdated=True, UpdateSourceTrigger=PropertyChanged}" SelectionChanged="groupTable_SelectionChanged" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto" Grid.IsSharedSizeScope="True" AlternatingRowBackground="#FFD6D1D1" CanUserAddRows="false" CanUserDeleteRows="False" CanUserReorderColumns="False" CanUserResizeColumns="False" CanUserResizeRows="False" IsReadOnly="True" Margin="0,0,-8,0" >
<DataGrid.ItemBindingGroup>
<BindingGroup/>
</DataGrid.ItemBindingGroup>
<DataGrid.Columns>
<DataGridTextColumn Header="RecordNumber" Width="100" Visibility="Hidden" />
<DataGridTextColumn Header="NAME" Width="200" Binding="{Binding GroupName}" />
<DataGridTextColumn Header="Group Name" Width="144" Binding="{Binding ParentGroupName}" />
<DataGridTextColumn Header="Creation Time" Width="200" Binding="{Binding CreationTime}" />
<DataGridTextColumn Header="Modification Time" Width="200" Binding="{Binding ModificationTIME}" />
<DataGridTextColumn Header="User" Width="100" Binding="{Binding PeopleName}" />
</DataGrid.Columns>
</dataGridFiltter:FilteringDataGrid>
我使用的风格如下： -

我收到DataGrid.ItemBindingGroup，DataGrid.Columns和DataGridTextColumn
有人可以帮助我使用上面代码的正确方法，因为我创建了subclass的{{1}}。
