The RadHtmlPlaceholder control gets misplaced when displayed inside a RadWindow in a zoomed browser. The issue can be reproduced in the HtmlPlaceholder WindowIntegration demo example.
The placeholder disappears if it's in a RadPane and you close another RadPane
Not measured correctly when no width/height is specified.
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.
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
MouseWheel does not work when setting an HtmlSource.
When displayed inside a RadWindow, if the window is moved outside the browser, the placeholder gets cut off. This issue also appears if initally the left side of RadWindow is positioned outside the browser.
Does not resize correctly in IE when surrounded by GridSplitters
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.
Height is not calculated properly when the content is wrapped.
The control cannot be placed inside ToolTip ContentTemplate
Currently, RadHtmlPlaceholder is an IFrame which is being rendered on top of the Silverlight plugin. Therefore, no mouse or keyboard events are being fired.
When PDF is shown, setting visibility to collapsed makes the web page blank
OnUnload/OnBeforeUnload do not fire after changing SourceUrl
Incorrect rendering under Mac and Safari
When the HtmlPlaceholder is placed in an ItemTemplate of a ListBox and if the HtmlPlaceholder.KeepContentInMemory is set to True, the control is rendered twice - in the ListBoxItems and in the top left of the page
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
