Challenge
I am working on a simple chat application using a System.Windows.Forms.WebBrowser Control to display the messages between the user and the recipient. How do I get the control to automatically scroll to the bottom every time I update the DocumentText of the control?
Solution
I tried to Google it and found below stuff which doesn’t work as expected.
ctlWebBrowser.Document.Body.ScrollIntoView(false);
// http://stackoverflow.com/questions/990651/system-windows-forms-webbrowser-scroll-to-end
webCtrl.Document.Window.ScrollTo(0, int.MaxValue);
// http://stackoverflow.com/questions/46454/webbrowsercontrol-scroll-to-bottom
Finally, I did it using following way:
[sourcecode language=”csharp”]
private void ScrollMessageIntoView()
{
// MOST IMP : processes all windows messages queue
System.Windows.Forms.Application.DoEvents();
if (webBrowserControlRcdMsg.Document != null)
{
webBrowserControlRcdMsg.Document.Window.ScrollTo(0,
webBrowserControlRcdMsg.Document.Body.ScrollRectangle.Height);
}
}
[/sourcecode]
