现在程序在实现多列，但不显示数据，如下代码：

<DataGrid Height="auto"                       ScrollViewer.IsDeferredScrollingEnabled="True"                       VirtualizingStackPanel.IsVirtualizing="True"                       VirtualizingStackPanel.VirtualizationMode="Recycling"                       EnableColumnVirtualization="True"                       CanUserAddRows="False"                                 AutoGenerateColumns="False" HorizontalAlignment="Left" Name="listView2" VerticalAlignment="Top" Width="auto" Margin="5,5,0,0"  ItemsSource="{Binding CheckManList}" >

     <DataGrid.ItemsPanel>                                 

            <ItemsPanelTemplate>                                

                  <UniformGrid Columns="6" />                            

            </ItemsPanelTemplate>                        

     </DataGrid.ItemsPanel>

     <DataGrid.ItemTemplate>                            

               <DataTemplate>                                

                        <TextBlock Text="{Binding Path=TheText}"/>                            

               </DataTemplate>                        

      </DataGrid.ItemTemplate>

</DataGrid>

请各位帮帮忙，谢谢！
