I am trying to configure both the Drawing and Chart controls to use Ajax in Visual Studio 2010.....

I have followed all of the examples and read everything in the online documentation about Ajax and it seems very straight forward. However when I load the page with the hosted Drawing or Chart control I get the following run-time error....


Dialog box with "Microsoft JScript runtime error: 'NChartCallbackService' is undefined"

The following line is from the dynamic output of the aspx page.

NChartCallbackService.RegisterWebControl(new NHttpCallbackConfiguration("ctl00$MainContent$chartSplitterPortUtilization", "MainContent_chartSplitterPortUtilization", 6000, 20, true, 10000, true, 1000, 5, ""), new NDiagnosticsConfiguration(ENDebugConsoleMode.Auto), new NToolFactory(new NToolConfiguration("NTooltipTool", true, new NTooltipToolConfig("", 1, 3))), new NMouseEventsConfiguration(50, 1, 20, 1, 10, 1, 100, 1, 100, 1), new NAutoRefreshConfiguration(false, 5000, 1));


Thanks for the help.......
