WebBrowser Control - How to suppress opening of new windows?

Hi,

I am working on kiosk-browser application. I would like to suppress opening of all new windows and force the webbrowser to open them in it. So I observe NewWindow event and cancel new window opening and then navigate to Url of the new window:

private void webBrowser_NewWindow(object sender, CancelEventArgs e)
{
      e.Cancel = true;
      webBrowser.Url = new Uri(webBrowser.StatusText);            
}

It works fine on many websites, HTML pages are correctly opened in webbrowser, PDF files are openen in webbrowser also (in acrobat reader plugin).

But - I have found one website where HTML anchors to PDF files are made like this (nothing unusual):

<a target="_blank" href="http://test.com/file.pdf">PDF file</a>

And for this link:

- NewWindow event is normally fired (no new browser-window is opened)

- browser pops-up windows that shows like file.pdf is being downloaded (to temp folder) and then this file.pdf is opened with Adobe Reader application (so not in browser).

If I make my testing html page and copy their anchor then everything works fine - file.pdf is opened in browser.

My question is: How to make all files open in webBrowser?

Thanks a lot

Hi,

I test on my side, write the following between body tag.

PDF file

</a>

When I click “pdf file�? webbroswer opens the pdf file inside.

I guess downloading and opening with Adobe Reader application actions cause by other setting.

Best regards,

As I have written - for almost all URL's it behaves as you wrote, it opens pdf file inside WebBrowser component.

But try this URL: Test URLinWebBrowser component the way I described.

Does it open in WebBrowser?
