Answer 1

Have you tried fireEvent instead of RaiseEvent?

Answer 2

Just a possible useful extra where the submit button has not been given an Id - as is frequently the case.

    private HtmlElement GetInputElement(string name, HtmlDocument doc) {
            HtmlElementCollection elems = doc.GetElementsByTagName("input");

            foreach (HtmlElement elem in elems)
            {
                String nameStr = elem.GetAttribute("value");
                if (!String.IsNullOrEmpty (nameStr) && nameStr.Equals (name))
                {
                    return elem;
                }
            }
            return null;
    }

So you can call it like so:

 GetInputElement("Login", webBrowser1.Document).InvokeMember("Click");

It'll raise an exception if the submit input with the value 'Login', but you can break it up if you want to conditionally check before invoking the click.

Answer 3

There is an example of how to submit the form using InvokeMember here. http://msdn.microsoft.com/en-us/library/ms171716.aspx

Answer 4

You posted a comment along the lines of not wanting to use a client side script on @Phunchak's answer. I think what you are trying to do is impossible. The only way to interact with the form is via a client side script. The C# code can only control what happens before the page is sent out to the browser.

Answer 5

How does this work? Works for me

HtmlDocument doc = webBrowser1.Document;

doc.All["userIDTextBox"].SetAttribute("Value", "user1");
doc.All["userPasswordTextBox"].SetAttribute("Value", "Password!");
doc.All["logonButton"].InvokeMember("Click");

Answer 6

var btn = document.getElementById(btnName); if (btn) btn.click();
