The following sample demonstrates how to set the values of the form input elements (text field or check box). The same approach will also work if there is no form.

{
public class WindowMain : Window
{
private WPFBrowserView browserView;
public WindowMain()
{
Browser browser = BrowserFactory.Create();
browserView = new WPFBrowserView(browser);
browser.FinishLoadingFrameEvent += delegate(object sender, FinishLoadingEventArgs e)
{
if (e.IsMainFrame)
{
DOMDocument document = e.Browser.GetDocument();
DOMInputElement firstName = (DOMInputElement)document.GetElementByName("firstName");
DOMInputElement lastName = (DOMInputElement)document.GetElementByName("lastName");
DOMInputElement agreement = (DOMInputElement)document.GetElementByName("agreement");
firstName.Value = "John";
lastName.Value = "Doe";
agreement.Checked = true;
}
};
Content = browserView;
Width = 1024;
Height = 768;
this.Loaded += WindowMain_Loaded;
}
void WindowMain_Loaded(object sender, RoutedEventArgs e)
{
browserView.Browser.LoadHTML("<html><body><form name=\"myForm\">" +
"First name: <input type=\"text\" name=\"firstName\"/><br/>" +
"Last name: <input type=\"text\" name=\"lastName\"/><br/>" +
"<input type='checkbox' name='agreement' value='agreed'>I agree<br>" +
"<input type=\"button\" value=\"Save\"/>" +
"</form></body></html>");
}
