关于aspxgridview里面过长内容只显示的一部分的处理方案

   protected void g_Message_CustomColumnDisplayText(object sender, ASPxGridViewColumnDisplayTextEventArgs e)
         {
             if (e.Column.FieldName == "字段")
             {
                 if (e.Value != null)
                 {
                     string cellValue = e.Value.ToString();
                     if (cellValue.Length > TextMaxLength)
                         e.DisplayText = cellValue.Substring(, TextMaxLength) + "...";
                 }
             }
         }

         protected void g_Message_HtmlDataCellPrepared(object sender, ASPxGridViewTableDataCellEventArgs e)
         {
             if(e.DataColumn.FieldName == "字段")
             if(e.CellValue != null)
                 e.Cell.ToolTip = e.CellValue.ToString();
          }
