I am using WebBrowser component in .NET to load a web page.
How do I get the value attribute of a radio button?

For example:
The HTML source code which let the user choose a color:
<input type="text" name="firstname" value="the name entered by user">
<input type="radio" name="myradio" value="red">Red
<input type="radio" name="myradio" value="blue" checked>Blue
<input type="radio" name="myradio" value="white">White

In C# code (C# Application), I wanted to get the value selected by the user.
I have the below code for getting their values:

========================
HtmlDocument document = this.webBrowser1.Document;
firstName = document.All["firstname"].GetAttribute("value");
color = document.All["myradio"].GetAttribute("value");
========================

I can get the correct value from the firstname textbox, however, the "color" radio button always returns the value "red" event when Red is not selected.

Please help!

I believe the problem is the way that radio buttons behave in the document object model. You need to look at the selected index of the radio button object. Then you look for the value of the selected item. In JavaScript you'd do this, perhaps it will apply to your situation as well with some alteration:

color = myradio[myradio.selectedIndex].value;

Thanks planoie. Yeah, it would have been easier with Javascript, however, I have no control over the other website.

I have come up with a working solution below:
If there's a simpler one, i'd be happy to use it :)


HtmlDocument document = this.webBrowser1.Document;
HtmlElementCollection input = document.All.GetElementsByTagName("input");
foreach (HtmlElement element in input)
{
   if (element.GetAttribute("type").ToLower() == "radio")
   {
      if (element.Name == "myradio" && element.GetAttribute("checked").ToLower() == "true")
         color = element.Value;
   }
}
