XtraReports 動態報表的建立

思路：簡單的報表顯示最基本的無非就是數據列信息和數據源，所以在XtraReports構造函數中傳入：一個要顯示的數據列的信息（此例中我用字符串表示），一個數據源（此例中我傳入數據表）。有了這兩個基本信息就足夠建立一個報表了，當然是簡單點的，其他的參數可以自己添加或刪減。以下是我寫的構造函數代碼，沒有經過優化和整理的，僅供參考和學習討論。 /// <summary> /// 構造函數－動態建列 /// </summary> /// <param name="BaoBiaoN">報表名稱</param> /// <param name="LieShu_LT">數據列數量</param> /// <param name="LieStr_LT">數據列明細</param> /// <param name="MyTable_MX">數據表</param> public XReport(string BaoBiaoN,int LieShu_LT,string LieStr_LT,DataTable MyTable_MX) { InitializeComponent(); dataSet_SJ.Tables.Add(MyTable_MX); this.DataSource = this.dataSet_SJ; this.xLabel_Name.Text = BaoBiaoN; this.xLabel_Date.Text = "打印時間："+System.DateTime.Now; this.xLabel_CZY.Text = "操作員："+QuanJuHanShu.UersN; string LieStr_bak=LieStr_LT; string LS_Lie; string LS_Lie_MX; XRTableCell MyTableCell_LT; XRTableRow MyTableRow_LT=new XRTableRow(); XRTable MyTable_LT = new XRTable(); ; for (int a = 0; a < LieShu_LT; a++) { if (LieStr_LT.Contains("$")) LS_Lie = LieStr_LT.Substring(0, LieStr_LT.IndexOf("$")); else LS_Lie = LieStr_LT; if (LS_Lie.Contains(",")) LS_Lie_MX = LS_Lie.Substring(LS_Lie.IndexOf(",") + 1, LS_Lie.LastIndexOf(",") - LS_Lie.IndexOf(",") - 1); else LS_Lie_MX = LS_Lie; MyTableCell_LT = new XRTableCell(); MyTableCell_LT.Name = LS_Lie_MX + "_LT"; MyTableCell_LT.Text = LS_Lie_MX; MyTableCell_LT.Borders = ((BorderSide)(BorderSide.All)); MyTableCell_LT.TextAlignment = TextAlignment.MiddleCenter; MyTableCell_LT.BackColor = Color.LemonChiffon; MyTableRow_LT.Cells.Add(MyTableCell_LT); LieStr_LT = LieStr_LT.Substring(LieStr_LT.IndexOf("$") + 1); } MyTable_LT.Size = new System.Drawing.Size(650, 28); MyTable_LT.Rows.AddRange(new XRTableRow[] {MyTableRow_LT}); this.PageHeader.Controls.AddRange(new XRControl[] {MyTable_LT}); XRBinding MyBinding_MX; MyTable_LT = new XRTable(); MyTableRow_LT = new XRTableRow(); for (int b = 0; b < LieShu_LT; b++) { MyTableCell_LT=new XRTableCell(); if (LieStr_bak.Contains("$")) LS_Lie = LieStr_bak.Substring(0, LieStr_bak.IndexOf("$")); else LS_Lie = LieStr_bak; LS_Lie_MX = LS_Lie.Substring(0,LieStr_bak.IndexOf(",")); MyTableCell_LT.Name = LS_Lie_MX; MyTableCell_LT.Borders = ((BorderSide)(BorderSide.All)); MyTableCell_LT.TextAlignment = TextAlignment.MiddleCenter; MyBinding_MX = new XRBinding(); MyBinding_MX = new XRBinding("Text", this.dataSet_SJ, dataSet_SJ.Tables["MyTab_gridView_MX"].Columns[b].ColumnName, ""); MyTableCell_LT.DataBindings.Add(MyBinding_MX); MyTableRow_LT.Cells.Add(MyTableCell_LT); LieStr_bak = LieStr_bak.Substring(LieStr_bak.IndexOf("$")+1); } MyTable_LT.Size = new Size(650,28); MyTable_LT.Rows.AddRange(new XRTableRow[] { MyTableRow_LT}); this.Detail.Controls.AddRange(new XRControl[] {MyTable_LT}); }

 

注意：在字段綁定數據源時，一定要用列名（string），不要使用索引形式，只有直接用列名數據纔可以正常顯示。
