Question

I have a standard ASP.NET web form in a web page, and this page is hosted in a .NET Winform with a WebBrowser Control. Using c# how do I control the WebBrowser Control to submit the ASP.NET form? (eg somehow “clicking” on the button from the Winform?)

Update: to complicate things we have the ASP.NET validators which seem to make simple document.forms(0).submit() not work

Answer 1

Because of the complication of the ASP.NET validators somehow messing with the normal form.submit() flow the submit button’s click method had to be called:

WebBrowser1.Document.getElementById("mybutton").InvokeMember("click");
