The Smart Tags for RadAjaxPanel and RadAjaxManager are nearly identical. The RadAjaxManager Smart Tag differs from the RadAjaxPanel version in that it has aConfigure Ajax Manager link and a "Choose DefaultLoadingPanelID" drop down list instead of "Choose LoadingPanelID". RadAjaxPanel also has a Add RadAjaxManager option.
