This only happens in IE8.  IE9, Chrome, FF3 and FF4 all work okay.  As soon as the componenet is set to visible the scrollbar appears because something has been added to the body html.  The suggested workaround to have the body style overflow set to hidden

Does not resize correctly in IE when surrounded by GridSplitters

The control cannot be placed inside ToolTip ContentTemplate

When placed in scrollviewer and browser is resized in order to appear the scrollbar, HTMLPlaceHodler doesn`t render correctly. The issue can be reproduced in both scenarios - setting the HtmlSource or SourceUrl property.

HtmlPlaceholder is renderred incorrectly in ChildWindow

Support for WebBrowserBrush.

When the user navigates in a page displayed in the placeholder and then it is removed and added in the visual tree (when in RadDocking for example) the original SourceUrl is displayed while ideally this should be the page that the user has navigated to.
Update: You can fix this by setting the HTMLPlaceholder's KeepContentInMemory property to True.

When RadHtmlPlaceholder is removed from the VisualTree doesn't clean up the html frames for it's inner html.

Make it easier to use the HtmlPlaceholder w/ scripts. Much like the WebBrowser control API.

Repro steps:
- Host RadHtmlPlaceholder in a RadWindow
- Set the HtmlPlaceholder content to be a PDF document
- Show the window and then minimize it
- Either restore or maximize the window
- The HtmlPlaceholder content is not rendered

When placed in a horizontal PanelBar, the HtmlPlaceholder is not rendered.

Not measured correctly when no width/height is specified.

Height is not calculated properly when the content is wrapped.
