How to get Index of the FORM Element in the WebBrowser Control?

let say a site has 2 forms: one search form and the other is a registratio开发者_Go百科n form...

<form>
Search: <input type="text" name="s">
<input type="hidden" name="a" value="search">
<input type="submit" value="Search">
</form>

[..]website content blabla[...]

<h2>Registration</h2>
<form>
E-Mail: <input type="text" name="email">
<input type="hidden" name="a" value="reg">
<input type="submit" value="Register">
</form>

If I submit a form, I want to know to which form the clicked submit button belongs. GetElementbyId is not possible because the id is not always available. I want to get the index. Any ideas? (WebBrowser Element in VB.NET or C#)


You cant refer to Form object of Input Element e.g btn.Form.Name should work; give it a try
