如何在 devexpress 数据网格中为每个列单元格制作上下文菜单？

   xmlns:dxg="http://schemas.devexpress.com/winfx/2008/xaml/grid"
  <dxg:GridControl  Grid.Row="0"  
                                  Height="150"

如何为每一列制作 ContextMenu？

例如，当上下文菜单单击第一列（单元格上属于第一列）时：它显示“Column1 菜单”项，当它单击第二列时（单元格上属于第二列）显示“Column2 菜单”项

我找到了答案：

 <dxg:GridControl.View>
                        <!--region #RowCellMenuCustomization-->
                        <dxg:TableView x:Name="view" AutoWidth="True">                             
                            <dxg:TableView.RowCellMenuCustomizations>

                                <dxb:BarButtonItem  Content="Menu1"                                           
                                       ItemClick="CellDataItem_Menu1_ItemClick"
                                                  Glyph="/MyCompany.UI.Resources;component/PNGImages/Menu1.png"
                                                   >
                               </dxb:BarButtonItem>                                                                      
                            </dxg:TableView.RowCellMenuCustomizations>
                        </dxg:TableView>

和处理程序：

private void CellDataItem_ByColumn_ItemClick(object sender, ItemClickEventArgs e)
    {
        var menuInfo = view.GridMenu.MenuInfo as GridCellMenuInfo;
        if (menuInfo != null && menuInfo.Row != null)
        {
            var column = menuInfo.Column as GridColumn;               
            if (column == null) return;

            if ((String)column.ActualColumnChooserHeaderCaption == _nameColumn)//context menu under column "Name"
            {
                //code here
            }
            else if(...)
            {}

        }
    }
