Hi, Let me try to describe the situation in a little bit more detail. This code will run in a kiosk, and will allow users to enter data to a couple of web pages, on which I have no control. The webbrowser control allows me to tap into key events using keypreview, but I need a way to determine the context of keypress when it comes to backspace. The user may be using backspace to erase a mistyped data, so I need to allow backspace only when the focus is in a textbox, and cancel the event on every other context. I've just seen that there is an ActiveElement property, and I'll look into it. I hope I can get the active element in htmldocument and using the tag name, I can allow or disallow backspace keypress. (I do not have access to my .net dev. environment at the moment)
Thanks for the suggestions and html editor link. Actually I've written a very complex app that used a webbrowser control as gui in 2002. I can barely remember using some other technique that was based on implementing an interface (a com interface I guess), but that's on old and faded memory now :) Cheers Seref On Fri, Aug 8, 2008 at 4:48 PM, Eames, Andrew <[EMAIL PROTECTED]> wrote: > Yup - Set the KeyPreview property to true on the Form that hosts the > control and handle the key events in the form > Andrew > > -----Original Message----- > From: Discussion of advanced .NET topics. > [mailto:[EMAIL PROTECTED] On Behalf Of John Warner > Sent: Friday, August 08, 2008 8:06 AM > To: ADVANCED-DOTNET@DISCUSS.DEVELOP.COM > Subject: [Spam:***** SpamScore] Re: [ADVANCED-DOTNET] Webbrowser control > and backspace key problem > Importance: Low > > Can you not capture the keystrokes at the form level and 'cancel' them > before they are bubbled to the control? > > John Warner > > > > > > -----Original Message----- > > From: Discussion of advanced .NET topics. > > [mailto:[EMAIL PROTECTED] On Behalf Of > > Peter Ritchie > > Sent: Friday, August 08, 2008 5:17 AM > > To: ADVANCED-DOTNET@DISCUSS.DEVELOP.COM > > Subject: Re: [ADVANCED-DOTNET] Webbrowser control and > > backspace key problem > > > > > > You'd run into this problem with a number of controls--many > > controls do something specific with certain keystrokes. > > > > I would recommend setting the focus away from the browser > > control while in on-screen keyboard mode.
