Cancels the asynchronous fetching of data.
The Cancel method is called to cancel a pending asynchronous execution by the
DataControl object.
An asynchronous call returns control to the calling program before the operation is completed
and allows the execution of the code to continue.
The ExecuteOptions property can enable an asynchronous fetch or a synchronous fetch.
The FetchOptions property determines the type of asynchronous fetch.
