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(0, 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();
         }
