New Post: Scrolling to end

I'm having trouble implementing https://htmlrenderer.codeplex.com/discussions/442448. There is no property called AutoScrollPosition, or AutoScrolling as described in the demo.

How do I scroll an HtmlPanel to end?

I'm using it to render html content from an Xmpp server and every time I update the Text property, the panel scrolls to the top.

Also open to a better method of appending content to the HtmlPanel.
