我已經創建了一個RDLC報告,當我在顯示網頁瀏覽器中它正常工作。但我的客戶現在希望我發送PDF文件到瀏覽器/客戶端,而不是在Web瀏覽器中顯示報告。當我添加代碼來創建報告的PDF並將其發送到客戶端/瀏覽器時,出現錯誤。 這裏是我的代碼發送PDF到客戶端/瀏覽器:RDLC報告錯誤:Microsoft.ReportingServices.ReportProcessing.ReportProcessingException
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetData"
TypeName="CourrierExpress.ExpressCourierDataSetTableAdapters.uspFrontEnd_Invoice_PrintInvoiceTableAdapter"
OldValuesParameterFormatString="original_{0}">
<SelectParameters>
<asp:QueryStringParameter Name="InvoiceId" QueryStringField="InvoiceId" Type="Int64"
DefaultValue="" />
</SelectParameters>
</asp:ObjectDataSource>
我頁面加載後面調用此代碼:
Int64 invoiceId = int.Parse(Request.QueryString["InvoiceId"]);
Warning[] warnings;
string[] streamIds;
string mimeType;
string encoding;
string extension;
var rds = new ReportDataSource { DataSourceId = "ObjectDataSource1", Name = "DataSet1" };
var viewer = new ReportViewer();
viewer.ProcessingMode = ProcessingMode.Local;
viewer.LocalReport.DataSources.Clear();
viewer.LocalReport.ReportPath = "Reports/ReportInvoicePrint.rdlc"; //This is your rdlc name.
viewer.LocalReport.DataSources.Add(rds);
var bytes = viewer.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension,
out streamIds, out warnings);
Response.Buffer = true;
Response.Clear();
Response.ContentType = mimeType;
Response.AddHeader("content-disposition", "attachment; filename= filename" + "." + extension);
Response.OutputStream.Write(bytes, 0, bytes.Length); // create the file
Response.Flush(); // send it to the client to download
Response.End();
RDLC報告中有一個名爲「數據集1」數據集。 錯誤截圖:
