The RadDiagram control offers a Smart Tag that lets you perform several basic actions:
Add the main manager controls from the suite:
The Add RadAjaxManager... link adds a RadAjaxManager component to your Web page, so you can configure partial postbacks through a comfortable control.
The Replace ScriptManager with RadScriptManager link replaces the default ScriptManager component that is used for AJAX-enabled Web sites with RadScriptManager. If there isn't a ScriptManager on the page this link will allow you to add one.
The Add AddRadStyleSheetManager link adds a RadStyleSheetManager to your Web page.
The Add ScriptManager link adds a ScriptManager component to your Web page.
Choose the skin - The Skin dropdown lists all available skins for the control so you can select one that matches the look and feel of the rest of the page. The skins are displayed via small images to give you a better idea of the color scheme they use.
