Pdf Library for .NET

Sending Parameters with a HTTP POST Request

By default, when a page is converted to PDF, SelectPdf performs a GET request for that page to obtain its content. SelectPdf Library for .NET can be used to send additional parameters to the web page that is converted using a HTTP POST request.

This can be done using the HttpPostParameters property of the HtmlToPdfOptions object.

Sample Code

This sample shows how to send parameters using a HTTP POST request to the page that will be converted using the html to pdf converter from SelectPdf Pdf Library for .NET.

// instantiate a html to pdf converter object
HtmlToPdf converter = new HtmlToPdf();

// set the HTTP POST parameters
converter.Options.HttpPostParameters.Add(TxtName1.Text, TxtValue1.Text);
converter.Options.HttpPostParameters.Add(TxtName2.Text, TxtValue2.Text);
converter.Options.HttpPostParameters.Add(TxtName3.Text, TxtValue3.Text);
converter.Options.HttpPostParameters.Add(TxtName4.Text, TxtValue4.Text);

// create a new pdf document converting an url
PdfDocument doc = converter.ConvertUrl(TxtUrl.Text);

// save pdf document
doc.Save(Response, false, "Sample.pdf");

// close pdf document
