下图显示了Windows资源管理器中Date modified列按升序排序的文件，该文件由向上指向的小箭头指示：

按下文提示的步骤可以很容易地在您的甘特图中实现舒适排列：

一、创建箭头

您需要两个用于显示箭头的图形文件，以下称为arrow-down.png和arrow-up.png， 它们必须作为Resources添加到Visual Studio解决方案中。

二、自定义表格格式

在XGantt表格StandardListCaption中，勾选所有字段的Text/Graphics combiined复选框。

三、添加代码

执行上述步骤后，向Gantt控件添加一些代码：

int _sortedByColumn = 3;private void Form1_Load(object sender, EventArgs e){   //Make the resources available for XGantt:   //In the following 2 lines the namespace has be be adjusted as necessary.  vcGantt1.SetImageResource("*ArrowDown",Default_Configuration.Properties.Resources.arrow_down);   vcGantt1.SetImageResource("*ArrowUp", Default_Configuration.Properties.Resources.arrow_up);    //Set the arrow in the table column by which your nodes are initially sorted:   VcTable activeTable = vcGantt1.TableCollection.Active;   VcTableFormat standardListCaptionTF = activeTable.TableFormatCollection.FormatByName("StandardListCaption");   //Select the table format field by which your nodes are initially sorted:   VcTableFormatField tff = standardListCaptionTF.get_FormatField(2);   tff.GraphicsFileName = "*ArrowUp";    //...} private void vcGantt1_VcTableCaptionLeftClicking(object sender, VcTableClickingEventArgs e){   VcNodeLevelLayout nodeLevelLayout = vcGantt1.NodeLevelLayout;   VcTableFormat standardListCaptionTF = e.Table.TableFormatCollection.FormatByName("StandardListCaption");    VcTableFormatField tff = standardListCaptionTF.get_FormatField((short)(e.ColumnNumber - 1));    if (e.ColumnNumber == _sortedByColumn)   //Clicked again on the same column: Just reverse the sort order!   {      if (nodeLevelLayout.get_SortOrder(0) == VcNodeSortingOrder.vcAscending)      {         nodeLevelLayout.set_SortOrder(0, VcNodeSortingOrder.vcDescending);         tff.GraphicsFileName = "*ArrowDown";      }      else      {         nodeLevelLayout.set_SortOrder(0, VcNodeSortingOrder.vcAscending);         tff.GraphicsFileName = "*ArrowUp";      }   }   else   //Clicked on another column: Sort by this column. Sort order: ascending   {      nodeLevelLayout.set_SortDataFieldIndex(0, tff.Index);      nodeLevelLayout.set_SortOrder(0, VcNodeSortingOrder.vcAscending);       tff.GraphicsFileName = "*ArrowUp";       tff = standardListCaptionTF.get_FormatField((short)(_sortedByColumn - 1));      tff.GraphicsFileName = string.Empty;   }    vcGantt1.SortNodes();    _sortedByColumn = e.ColumnNumber;}

四、结果展示

如果一切都按计划进行，甘特图中的表格标题现在应该显示排序箭头，如下图所示：
