我有一个用ASP.NET
开发的Web应用程序。我正在使用rdlc
进行报告。一切似乎在我的开发机器上都可以正常运行,但是当我将应用程序上传到托管服务(GoDaddy.com)时,一切都没有。报告显示为预览(ReportViewer控件)。但是,当我单击“打印”时,它没有显示预览。
public void print()
{
try
{
Warning[] warnings;
string[] streamids;
string mimeType;
string encoding;
string extension;
byte[] bytes = ReportViewer1.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);
FileStream fs = new FileStream(HttpContext.Current.Server.MapPath("output.pdf"), FileMode.Create);
fs.Write(bytes, 0, bytes.Length);
fs.Close();
//Open exsisting pdf
Document document = new Document(PageSize.A4);
PdfReader reader = new PdfReader(HttpContext.Current.Server.MapPath("output.pdf"));
//Getting a instance of new pdf wrtiter
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(HttpContext.Current.Server.MapPath("Print.pdf"), FileMode.Create));
document.Open();
PdfContentByte cb = writer.DirectContent;
int i = 0;
int p = 0;
int n = reader.NumberOfPages;
Rectangle psize = reader.GetPageSize(1);
float width = psize.Width;
float height = psize.Height;
//Add Page to new document
while (i < n)
{
document.NewPage();
p++;
i++;
PdfImportedPage page1 = writer.GetImportedPage(reader, i);
cb.AddTemplate(page1, 0, 0);
}
//Attach javascript to the document
PdfAction jAction = PdfAction.JavaScript("this.print(true);\r", writer);
writer.AddJavaScript(jAction);
document.Close();
//Attach pdf to the iframe
frmPrint.Attributes["src"] = "Print.pdf";
}
catch (Exception ex)
{
Response.Write("<script>alert('Error Occured')</script>");
}
}
我正在使用上面的代码进行打印。
