Web Chart ClickSeries - Invalid parameter used.

I have a Web application that I am porting over from MS.Net v 1.0 to MS.Net v1.1.

I am testing Microsofts Enterprise Library for data access and everything seems to be working well until I tried to wire up the Webchart ClickSeries event. Even with no code in the event handler I get the following message ......

Invalid parameter used.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentException: Invalid parameter used.

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Any help would be gratly received.
