Website Automation Using C# and WebBrowser

Question

hi,

I am building an application which opens a website in WebBrowser control and then puts some text in fields and then clicks submits on few buttons one after another.

Have a look at code bellow...

var doc = webBrowser1.Document.GetElementById("ddlOnBoro");
doc.SetAttribute("SelectedIndex", "3");
var temp = doc.InvokeMember("change");

doc = doc.Document.GetElementById("iddOnstreet_txTextBox");
doc.SetAttribute("value", "ASTOR PLACE");

var adoc = doc.Document.GetElementById("Button6");
var getCrossStreets = adoc.DomElement as mshtml.HTMLInputButtonElement;
adoc.RaiseEvent("onclick");

First and last 3 lines work good and even middle 2 works fine but when I RaiseEvent("onclick") in the last line of code, the value of textbox gets blank before being submitted even I've set it in 5th line of code.

The website is built into ASP.NET and I think this is ViewState that is messing up with.

Any ideas?

As reference, check if the popular iMacros browser macro recorder can handle this website. If yes, then you know at least that it is doable.
