.net报表rdlc

这次系统用的报表是vs2010自带的rdlc报表，感觉还蛮实用的，不错。
在这里就说下，使用的过程，因为之前都是vs2008与2010还是有区别的。
   1、简历rdlc文件
   2、画图
   3、建立数据源---此数据源只是个占位符的意思，与前端页面并不对应
   4、代码贴上
    页面代码：
<div class="column">
        <div class="columntitle">
            材料入库报表</div>
        <div class="columncontent">
            <table cellspacing="0" cellpadding="0" id="tb_report" rules="all" align="center"
                border="0" style="border-width: 0px; width: 100%; border-collapse: collapse;">
                <tr>
                    <td>
                        <rsweb:reportviewer id="ReportViewer2" runat="server" font-names="Verdana" width="100%"
                            font-size="8pt" interactivedeviceinfos="(集合)" waitmessagefont-names="Verdana"
                            waitmessagefont-size="14pt" pagecountmode="Actual">
                <LocalReport ReportPath="materialReport\Report1.rdlc">
                </LocalReport>
            </rsweb:reportviewer>
                        <asp:ScriptManager ID="ScriptManager1" runat="server">
                        </asp:ScriptManager>
                    </td>
                </tr>
            </table>
        </div>
    </div>

后台代码：

ReportParameter p1 = new ReportParameter("ReportParameter1", str);
            ReportParameter p2 = new ReportParameter("ReportParameter2", "材料入库");
            ReportParameter p3 = new ReportParameter("ReportParameter3", "入库数量");
            ReportParameter p4 = new ReportParameter("ReportParameter4", "入 库 人");



            DataTable tb_r = MakeTable();
            int sumCount = 0;
            if (tb.Rows.Count > 0)
            {

                for (int i = 0; i < tb.Rows.Count; i++)
                {
                    DataRow row = tb_r.NewRow();
                    string dd = tb.Rows.Count.ToString();
                    row["MaterialIDName"] = tb.Rows[i]["MaterialIDName"].ToString();
                    row["Type"] = tb.Rows[i]["JionCount"].ToString();
                    row["Offer"] = tb.Rows[i]["JionName"].ToString();
                    tb_r.Rows.Add(row);
                    sumCount += Convert.ToInt32(tb.Rows[i]["JionCount"].ToString());
                    if(i==tb.Rows.Count-1){
                        DataRow row1 = tb_r.NewRow();
                        row1["MaterialIDName"] = "总计";
                        row1["Type"] = sumCount.ToString();
                        row1["Offer"] = "----";
                        tb_r.Rows.Add(row1);
                    }
                }
            }

            ReportViewer2.Style.Add("display", "");
            this.ReportViewer2.LocalReport.DataSources.Clear();
            this.ReportViewer2.LocalReport.SetParameters(p1);
            this.ReportViewer2.LocalReport.SetParameters(p2);
            this.ReportViewer2.LocalReport.SetParameters(p3);
            this.ReportViewer2.LocalReport.SetParameters(p4);

            this.ReportViewer2.LocalReport.DataSources.Add(new ReportDataSource("DataSet1", tb_r));



//虚拟一个报表表格
        private DataTable MakeTable()
        {
            DataTable tbl = new DataTable("report");

            DataColumn Column1 = new DataColumn();//材料名称
            Column1.ColumnName = "MaterialIDName";
            Column1.DataType = System.Type.GetType("System.String");
            Column1.AllowDBNull = true;
            tbl.Columns.Add(Column1);

            DataColumn Column2 = new DataColumn();//采购数量
            Column2.ColumnName = "Type";
            Column2.DataType = System.Type.GetType("System.String");
            Column2.AllowDBNull = true;
            tbl.Columns.Add(Column2);

            DataColumn Column3 = new DataColumn();//采购人
            Column3.ColumnName = "Offer";
            Column3.DataType = System.Type.GetType("System.String");
            Column3.AllowDBNull = true;
            tbl.Columns.Add(Column3);

            return tbl;
        }
