ext多表头,如何实现ASPxGridView的多表头功能

关于如何实现ASPxGridView的多表头功能，写了一个公共方法可供使用，调用时只许在绑定方法前面调用即可。
代码如下：
//调用该方法即可 public static void SetAspxGridViewBand(DevExpress.Web.ASPxGridView.ASPxGridView gridView) { gridView.HtmlRowCreated += new DevExpress.Web.ASPxGridView.ASPxGridViewTableRowEventHandler(GridView1_HtmlRowCreated); } static void GridView1_HtmlRowCreated(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewTableRowEventArgs e) { DevExpress.Web.ASPxGridView.ASPxGridView gridView = sender as DevExpress.Web.ASPxGridView.ASPxGridView; ////if the first data row has been added if (e.RowType == DevExpress.Web.ASPxGridView.GridViewRowType.Data && e.VisibleIndex == gridView.PageIndex * gridView.SettingsPager.PageSize) { Table table = e.Row.Parent as Table; if (table != null) { TableRow row = new TableRow(); TableCell firstBand = GetNewTableCell(row, string.Empty); foreach (DevExpress.Web.ASPxGridView.GridViewDataColumn col in gridView.Columns) { if (col.FieldName.IndexOf("|") > 0) { string bandname = col.FieldName.Substring(0, col.FieldName.IndexOf("|")); TableCell band = null; foreach (TableCell t in row.Cells) { if (t.Text == bandname) { band = t; break; } } if (band == null) { band = GetNewTableCell(row, bandname); } col.Caption = col.FieldName.Substring(col.FieldName.IndexOf("|") + 1); band.ColumnSpan++; } else { firstBand.ColumnSpan++; } } table.Rows.AddAt(0, row); } } } //可以在此修改单元格样式 private static TableCell GetNewTableCell(TableRow row, string bandname) { TableCell band = new TableCell(); band.Text = bandname; row.Cells.Add(band); band.CssClass = "dxgvHeader"; band.HorizontalAlign = HorizontalAlign.Center; band.BorderStyle = BorderStyle.NotSet; band.BorderColor = row.BorderColor; return band; }

注意：
1、该方法在绑定方法之前调用。
2、需合并的单元格的 列需如下设置：


按照“|”分割判断，相同的则会总动合并。
