Webbrowser; select radio button

Question

Hi I am making an autofill-program and have some issues with selecting radiobuttons. I use Visual C# 2010 express edition. Normally I just use getelementsbyid setattribute and invokemember but I don't see how I can select a radiobutton without id. Maybe I need to edit the html to make a radiobutton checked and then just use invokemember to submit? type = radio name = x1 value = ve > Vero type = radio name = x1 value = ee > Eee type = radio name = x1 value = wa > Walla type = radio name = x1 value = qu > Quack As you see there is no default select. I'am new to C# so I don't know what it can do but it would be cool to learn how to edit websites html through C#. I really just need to add checked to one of them radiobutton. I have a lot of experience with html so if I can find out how I can use C# to find and insert code; it would be great. Best Regards Kenneth

I have tried both solutions but they seems very hard to learn. I can't find any good beginner-materiall. Maybe someone can help throw out some examples?

Check out the HTML Agility Pack to do all sorts of HTML manipulation It gives you an interface somewhat similar to the XmlDocument XML handling interface: HtmlDocument doc = new HtmlDocument (); doc . Load ( file.htm ); HtmlNode bodyNode = doc . DocumentNode . SelectSingleNode ( /html/body ); if ( bodyNode != null ) { // do something } or you can refer to a good blog on HTML editing in c# here

Do you have any good sources on this subject? Would be great :)

Hi friend The html files can be treated as XML files so you can use XML classes to manipulate the HTML attributes. so as per your requirement you can insert the checked attribute into the radio button.
