Asynchronously cancels the transaction associated with the supplied transaction token.

Namespace: ININ.IceLib.Data.TransactionBuilder
Assembly: ININ.IceLib.Data.TransactionBuilder (in ININ.IceLib.Data.TransactionBuilder.dll) Version: 0.0.0.0 (22.3.0.218)

Syntax

C#
public void CancelTransactionAsync(
	string transactionToken,
	EventHandler<CancelTransactionCompletedEventArgs> completedCallback,
	Object userState
)
Visual Basic
Public Sub CancelTransactionAsync ( _
	transactionToken As String, _
	completedCallback As EventHandler(Of CancelTransactionCompletedEventArgs), _
	userState As Object _
)

Parameters

transactionToken
Type: System..::..String
The transaction token associated with the transaction to cancel.
completedCallback
Type: System..::..EventHandler<(Of <(<'CancelTransactionCompletedEventArgs>)>)>
The callback to invoke when the asynchronous operation completes.
userState
Type: System..::..Object
An optional object that contains state information for this request. This object is a way for the caller to store context information which will be provided to the AsyncCompleted event. If no context information is desired then nullNothingnullptra null reference (Nothing in Visual Basic) may be supplied.

Remarks

The CompletedAction should be set and will be raised when the transaction is cancelled. When raised, the Cancelled property of the ExecuteCompletedEventArgs instance will be set to trueTruetruetrue (True in Visual Basic).

Remarks

When completed, the completedCallback delegate is invoked on a thread appropriate to the application-model, such as the GUI thread in a UI application. The Error property of the AsyncCompletedEventArgs-derived object passed to the delegate will contain any exceptions thrown while executing the asynchronous task. See the synchronous version of this method for more detailed error information. For more information on async method calls, see How Async Calls Work.

Exceptions

System..::..ArgumentNullExceptionA parameter is nullNothingnullptra null reference (Nothing in Visual Basic).
