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 postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

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.

Your datepicker is created as a client side control - presumably you have put an input tag into your html. This is your problem. ASP.Net will not recognise it as a control that needs validating however, when you post back it will see the control there and so throw the above error as it does not know about it. To solve your problem you should wither create the control dynamically server-side or you should using <asp:TextBox> tags instead of input tags. Hope this helps, Ed :)
