Methods

	Name	Description
	CancelAsync	Cancels the asynchronous call, returning immediately.
	DeriveParametersAsync	Derives, in an asynchronous manner, a set of parameters for use with a specified command.
	DeriveSchemaAsync	Derives, in an asynchronous manner, the schema of the specified command.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	ExecuteAsync	Executes a command in an asynchronous manner.
	ExecuteWithoutResultsAsync	Executes, in an asynchronous manner, a command that does not return any results beyond an integer value indicating status.
	Finalize	Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnCancel	Dispatches the asynchronous cancel operation to the appropriate synchronous method.
	OnDeriveParameters	Dispatches the asynchronous derive parameters operation to the synchronous DeriveParameters method call.
	OnDeriveParametersCompleted	Raises the DeriveParametersCompleted event.
	OnDeriveSchema	Dispatches the asynchronous derive schema operation to the synchronous DeriveSchema method call.
	OnDeriveSchemaCompleted	Raises the DeriveSchemaCompleted event.
	OnExecute	Dispatches the asynchronous execute operation to the synchronous Execute method call.
	OnExecuteCompleted	Raises the ExecuteCompleted event.
	OnExecuteWithoutResults	Dispatches the asynchronous execute-without-results operation to the synchronous ExecuteWithoutResults method call.
	OnExecuteWithoutResultsCompleted	Raises the ExecuteWithoutResultsCompleted event.
	OnPrepare	Dispatches the asynchronous prepare operation to the synchronous Prepare method call.
	OnPrepareCompleted	Raises the PrepareCompleted event.
	OnSiteChanged	Raises the SiteChanged event. (Inherited from DataSiteableObject<T>.)
	PrepareAsync	Prepares, in an asynchronous manner, the specified command to be executed against the data source; the command may then be executed multiple times, with varying parameters.
	ToString	Returns a String that represents the current Object. (Inherited from Object.)

Properties

	Name	Description
	Site	Gets or sets the object site. (Inherited from DataSiteableObject<T>.)

Events

	Name	Description
	DeriveParametersCompleted	Occurs when the DeriveParametersAsync command is completed.
	DeriveSchemaCompleted	Occurs when the DeriveSchemaAsync command is completed.
	ExecuteCompleted	Occurs when the ExecuteAsync command is completed.
	ExecuteWithoutResultsCompleted	Occurs when the ExecuteWithoutResultsAsync command is completed.
	PrepareCompleted	Occurs when the PrepareAsync command is completed.
	SiteChanged	(Inherited from DataSiteableObject<T>.)
