参数问题

您好，
我使用DropDownList来实现选择周。选择后触发事件，在这个事件中加载新的模板。
初始化list

this.DropDownList1.Items.Insert(0, new ListItem("---选择---", "0"));
this.DropDownList1.Items.Insert(1, new ListItem("6周", "6周"));
this.DropDownList1.SelectedIndex = 0;

复制代码

选择是触发的事件

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
// Provide the page report you want to render.
GrapeCity.ActiveReports.PageReport report = new GrapeCity.ActiveReports.PageReport(new System.IO.FileInfo(Server.MapPath("积成电子3.rdlx")));
GrapeCity.ActiveReports.Document.PageDocument reportDocument = new GrapeCity.ActiveReports.Document.PageDocument(report);
report.Report.ReportParameters[0].DefaultValue.Values.Add(DropDownList1.SelectedValue);
// Provide settings for your rendering output.
GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtensionSettings excelSetting = new GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtensionSettings();
excelSetting.FileFormat = GrapeCity.ActiveReports.Export.Excel.Page.FileFormat.Xlsx;
excelSetting.OpenXmlStandard = GrapeCity.ActiveReports.Export.Excel.Page.OpenXmlStandard.Transitional;
excelSetting.Pagination = false;
GrapeCity.ActiveReports.Extensibility.Rendering.ISettings setting = excelSetting;
//Set the rendering extension and render the report.
GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtension excelRenderingExtension = new GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtension();
GrapeCity.ActiveReports.Rendering.IO.MemoryStreamProvider outputProvider = new GrapeCity.ActiveReports.Rendering.IO.MemoryStreamProvider();
reportDocument.Render(excelRenderingExtension, outputProvider, excelSetting.GetSettings());
System.IO.Stream stream = outputProvider.GetPrimaryStream().OpenStream();
// 通过Spread查看报表
FpSpread1.OpenExcel(stream);
FpSpread1.EnableViewState = false;
FpSpread1.SaveViewStateToSession = false;
FpSpread1.Sheets[0].OperationMode = FarPoint.Web.Spread.OperationMode.SingleSelect;
FpSpread1.Sheets[0].AllowPage = false;
FpSpread1.Sheets[0].FrozenRowCount = 2;
FpSpread1.Sheets[0].FrozenColumnCount = 4;
FarPoint.Web.Spread.HyperLinkCellType hlct = new FarPoint.Web.Spread.HyperLinkCellType("http://gcdn.gcpowertools.com.cn");
for (int row = 4; row < FpSpread1.Sheets[0].RowCount; row += 3)
{
for (int col = 4; col < FpSpread1.Sheets[0].ColumnCount; col++)
{
if (FpSpread1.Sheets[0].Cells[row, col].Value != null)
{
FpSpread1.Sheets[0].Cells[row, col].CellType = hlct;
}
}
}
}

复制代码

asp页面增加

<asp:DropDownList ID="DropDownList1" runat="server" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" AutoPostBack="True"></asp:DropDownList>
