getting content of a webbrowser control

Question

hi i'm loading a static html website in a webbrowser. the site contains a textarea (with javascript to create a html editor). after changing the text in the area i want to extract the text for use in my program. but textBox1.Text = webBrowser5.Document.Body.Children[0].Children["elm1"].InnerHtml; gives the original text (before any changes). how can i get the current text?
