Dev控件学习-GridControl中的BandGridview导出多层行头操作

BandGridview默认导出的是Columns的列头信息，而不是Bands的列头信息，为了实现导出多层行头。代码如下

  public static void ExportExcel2(DevExpress.XtraGrid.Views.BandedGrid.BandedGridView bandedGridView)
         {
             SaveFileDialog saveFileDialog = new SaveFileDialog();
             saveFileDialog.Title = "导出Excel";
             saveFileDialog.Filter = "Excel文件(*.xlsx)|*.xlsx";
             DialogResult dialogResult = saveFileDialog.ShowDialog();
             if (dialogResult == DialogResult.OK)
             {
                 DevExpress.XtraPrinting.XlsxExportOptionsEx op = new DevExpress.XtraPrinting.XlsxExportOptionsEx();

                 op.ExportType = DevExpress.Export.ExportType.WYSIWYG;
                 bandedGridView.OptionsPrint.PrintHeader = false;
                 bandedGridView.OptionsPrint.AutoWidth = false;
                 bandedGridView.ExportToXlsx(saveFileDialog.FileName, op);
                 DevExpress.XtraEditors.XtraMessageBox.Show("保存成功！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
             }
         }

其中需注意几点：

1.有两种Options:DevExpress.XtraPrinting.XlsxExportOptions和DevExpress.XtraPrinting.XlsxExportOptionsEx，需使用:DevExpress.XtraPrinting.XlsxExportOptionsEx;

2.DevExpress.Export.ExportType的方式有两种：DataAware和WYSIWYG；默认为DataAware，需设置为WYSIWYG；

3.OptionsPrint下的各属性默认值都为true，需设置PrintHeader = false(不显示列头)和AutoWidth = false(不自适应宽度)
