There is no error.A blank pdf page is generated.

protected void txtPDF_Click(object sender, EventArgs e)
{

PDFReport pdfReport = new PDFReport();
pdfReport.ReportProperty.ReportTable = "Bill";

pdfReport.ReportProperty.Columns = new System.Collections.Generic.Dictionary<string, string="">();

pdfReport.ReportProperty.Columns.Add("Emp Code", "Employee Code");
pdfReport.ReportProperty.Columns.Add("Status", "Employee Status");
pdfReport.ReportProperty.Columns.Add("Bill Type", "Employee BillType");
pdfReport.ReportProperty.Columns.Add("Financial Yr", "Financial Year");
pdfReport.ReportProperty.Columns.Add("Bill Date", "Bill Date From");
pdfReport.ReportProperty.Columns.Add("Approve Date", "Bill Date To");
Literal1.Text = pdfReport.HTMLToPdf(pdfReport.ReportProperty, "C:\\temp.pdf",Response.OutputStream);

}

this is my on button click event.

What will be Chap0101.pdf in case of table from database generated through a dll?

I have taken this code as reference.

I am sorry but this ain't my problem. The issue is that the pdf page gets generated but no data gets displayed over it. Perhaps it is not reading the table from the database.
