title: Handle IE To filling a form c#
body: <p>I want to navigate a website, login and fill a form through my application without seeing users anything and finally show it to users for submitting.</p>
  
  <p>Previously I used webbrowser control. It works usually but sometimes, some error raised on site after user submit form. but in IE this errors not raised with same data.</p>
  
  <p>Is there any way to navigate and fill forms with my data in IE directly and then show it to users? (this site has so many client side controls that I must wait to respond them to my data (for example load cities after select state)</p>
