Develop Simple Web Browser Using C#

This tutorial will explain, how to develop a Web browser which Navigate URL in the Text Box using C#(Sharp). Text Box mentioned here is the address bar of your Web Browser. PreviousIy I have written some article about how to develop a Simple Web Browser and how to add some features to it using C# (Sharp), you can refer that for more details. You are recommended to use Microsoft Visual Studio. We have screen shots here and have a look at it, same URL but two different blog contents, doesn’t it look annoying? When you execute the Bowser, it automatically loads Hellboundbloggers.com content and after I click on Home Button, browser loads tekkieblog content. The issue here is, it will not display the URL of tekkieblog.com in the Adress bar. When I again click on back button it loads Hellboundbloggers.com content with HBB URL in the Adress bar. There is no change in the URL because the Adress bar does not Navigate the URL and it only displays the content. So, to display appropriate URL in the Address bar while Navigating, we have to fire two events namely Text Changed Event of the Text Box and the Navigated Event of the Web Browser Control.
