I have a C# WinForms app that runs the WebBrowser control to automatically login, navigate through some pages, and ultimately arrive to page that displays a PDF. I would like to automatically save this PDF whenever I arrive to this page but I have been unable to do this automatically.
Is there a way to automatically click "save" in the webBrowser1.ShowSaveAsDialog() window? Or is there another way to save the PDF that I have successfully displayed in the webbrowser?
Additionally, I have tried to download the PDF using WebClient but this returns a HTML page with failed user/password info. Also, webBrowser1.Document is null so I'm unable to access the document as I would other pages in this routine.

I have been given a task to load a pdf into an iframe. That pdf contains numerous links that points to another pdf. On clicking any link I have to show the destination in another pdf.That pdf should be loaded into second iframe. I am in the middle of nowhere in this situation and I am new in handling pdfs. Please suggest what should be done. I can modify the source pdf using itextsharp(if needed). I am using c#.
I am filling form fields on a PDF with iTextSharp. The user enters data into a web-based form, then clicks a Create PDF button. The PDF then opens in the browser with the user entered text displaying in the applicable areas of the PDF.
I would like to allow the user to then manually add additional information into form fields directly on the PDF within the browser. We do not collect all information necessary in the web-based form; the user currently prints the PDF and writes the additional information in.
I want to show javascript code in my webbrowsers in C#. Normally, When I navigated, browser wants to save it.. But I want browser shows it on browser's screen.. I think that I must do a javascript viewer with webbrowser..
I used like that code but it doesnt work (still asking to save..)
webBrowser1.Navigate("http://xxxx.com/aaa.js", "_mainframe");
Don't use a WebBrowser control for this but simply download it using a HttpClient and display it e.g. in a TextBox.
The WebBrowser control is basically an embedded IE which will download files if it thinks a file with that MIME type should be downloaded or if there are headers like Content-disposition: attachment (which force a download prompt in the browser).
I want to display Pdf file inside iframe control.I have added my code like this below.
in asp page,
<iframe width=500 height=500 runat="server" id="myPDF" src="pdf_003.pdf"></iframe>
in page_load
myPDF.Attributes.Add("src", "pdf_003.pdf");
When i run the project, then the pdf file is not visible inside the iframe.Instead of this, it shown the save as dialog box for save to disk or open in pdf reader.
it is correctly shown in internet explorer but not any other browser...
How do i view the pdf file inside iframe control in all other browser?
Please Guide me to get out of this issue?
You need to change Acrobat Reader's settings so it will display PDF files on the browser itself.
See this Adobe KB article
I have a webbrowser control in my winforms application to display a selected pdf file, after this i want to move the pdf file to an other location.
When i trie to move the pdf file it is giving me an error that the file is in use. I tried to make the webbrowser navigate to a other page before it is moved but it still give me this error that the file is used by an other process.
How can i release this pdf file so i can just move it? Disposing the webbrowser didn't do the trick.
They say "Adobe Acrobat and Adobe Reader are designed to continue running for a few minutes after you close the browser window in which you viewed PDF files."
The workaround for this seems to be :
Copy the PDF to a temporary file and display it, and then when you navigate away, it doesn't matter if AcroRD32.exe holds onto the PDF for a few minutes because you can still do what you need with the original!
The following code releases for me the pdf file, which was displayed in WebBrowser, so I can move it:
webBrowser.Navigate("about:blank")

I have had a similiar problem, which was that the form with opened pdf file in browser was hidden and then a new instance of the form was opened, which triggered the same file locked error. For me Disposing of the WebBrowser control just before hiding the form helped.
