I have a vb.net page that has a iframe and a link button on it. When I click the link button I change the src of the iframe to lets say "http://www.testlogin.com
". Once test.login is loaded I want to enter a username and password using findcontrol. My problem is I don't when the page has completed loading. How do I do this with an Iframe. I am not using the webbrowser control because I am not using windows forms. This is a web app.
