Cannot bind to an empty custom collection.
posted

  I have a custom business object that inherits from List<t> that I am binding to using ObjectDataSource.  It works great when there is data present.  However, if there is no data returned, I get the following error:

Data source contains no schema data.

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.NotSupportedException: Data source contains no schema data.

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.

Stack Trace:

I am completely stuck on this one.  Any help would be greatly appreciated.
