I am trying to make a report in .net using c# with a table that has 2 columns. The problem is that I keep getting the same exception, which is LocalProcessingException, and occurs on this line:
byte[] bytes = lr.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);
the c# code is like this:
using System;
using System.Data;
using System.Configuration;
using System.Web.Security;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using Microsoft.Reporting.WebForms;
using System.IO;
public partial class Repo : System.Web.UI.Page
{
private LocalReport lr = new LocalReport();
private DataTable LoadSalesData()
{
// Load data from XML file.
DataSet dataSet = new DataSet();
dataSet.ReadXml(@"c:\Reports\xxx.xml");
return dataSet.Tables[0];
}
protected void Page_Load(object sender, EventArgs e)
{
lr.DataSources.Add(new ReportDataSource("Sales", LoadSalesData()));
lr.ReportPath = "Report.rdlc"; //@"c:\Reports\Report.rdlc";
//this.ReportViewer1.ProcessingMode = ProcessingMode.Local;
//this.ReportViewer1.LocalReport.ReportPath =
// @"c:\Reports\Report.rdlc";
//ReportViewer1.LocalReport.DataSources.Add(
// new ReportDataSource("Sales", LoadSalesData()));
}
protected void Button1_Click(object sender, EventArgs e)
{
Warning[] warnings;
string[] streamids;
string mimeType;
string encoding;
string extension;
byte[] bytes = lr.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);
FileStream fs = new FileStream(@"c:\output.pdf", FileMode.Create);
fs.Write(bytes, 0, bytes.Length);
fs.Close();
Response.AppendHeader("content-disposition", "attachment; filename=" + "mira.pdf"); // Forçar o download dialog
string type = "Application/pdf";
Response.ContentType = type;
Response.WriteFile(@"c:\output.pdf");
Response.End();
//File.Delete(@"c:\output.pdf");
//Label1.Text = "Report exported to output.xls";
}
}

Can you please help me with this? If you need more info or files please let me know. Thank you for your time.
I have found that you sometimes need to look at several InnerExceptions until you find the correct exception. I wrote a loop to dig into the deepest inner exception and report on that.
