ControlDesigner::InvokeTransactedChange Method (IServiceProvider, IComponent, TransactedChangeCallback, Object, String, MemberDescriptor)
Wraps a series of changes into a transaction, using the specified parameters that can be rolled back as a unit with the undo functionality of the design host.
Assembly: System.Design (in System.Design.dll)
public: static void InvokeTransactedChange( IServiceProvider^ serviceProvider, IComponent^ component, TransactedChangeCallback^ callback, Object^ context, String^ description, MemberDescriptor^ member )
Parameters
- serviceProvider
- Type: System::IServiceProvider
An IServiceProvider object representing the design host that provides control designer services for the associated control.
- component
- Type: System.ComponentModel::IComponent
The control associated with the control designer.
- callback
- Type: System.Web.UI.Design::TransactedChangeCallback
A TransactedChangeCallback object representing a function to call in the control designer as part of the transaction.
- context
- Type: System::Object
An object that contains the argument for callback.
- description
- Type: System::String
A description of the effect of allowing the transaction to complete, which is used by the design host to give the user an opportunity to cancel the transaction.
- member
- Type: System.ComponentModel::MemberDescriptor
A MemberDescriptor object (typically either an EventDescriptor or a PropertyDescriptor object) that describes the member of the associated control that is being invoked as part of the transaction.
| Exception | Condition |
|---|---|
| ArgumentNullException | component is nullptr. -or- callback is nullptr. -or- serviceProvider is nullptr. |
The implementation of the InvokeTransactedChange method notifies the design host, which is represented by serviceProvider, that a change is occurring to the specified member (property or method) of the associated control and, if the change is not canceled by the design host, invokes the specified callback using the specified context as the argument, and then notifies the design host that the change has completed.
If the design host or the associated control throws a static Canceled exception field of a CheckoutException exception, the transaction is canceled without invoking callback.
