Reset the scroll position
The scroll position can be moved programmatically to show the selected item with the help of the ScrollToElement method of the HTMLUI control. The ScrollToElement method helps the user to scroll to a position such that the specified element is visible in the HTMLUI control.
The following HTML document contains a div element and the code snippet below shows how the HTMLUI control is scrolled to make the div element visible.

this.div = html["div1"] as DIVElementImpl;
}
private void button1_Click(object sender, System.EventArgs e)
{
this.htmluiControl1.ScrollToElement(this.div);
}

End Sub
