The System.Web.UI.WebControls.ObjectDataSourceView object assumes that the method that is identified by the ObjectDataSourceView.UpdateMethod property performs updates one at a time, rather than in a batch.

The method can be an instance method or a static (Shared in Visual Basic) method. If it is an instance method, the business object is created and destroyed each time the method specified by the ObjectDataSourceView.UpdateMethod property is called. You can handle the ObjectDataSourceView.ObjectCreated event to work with the business object before the method specified by the ObjectDataSourceView.UpdateMethod property is called. You can also handle the ObjectDataSourceView.ObjectDisposing event that is raised after the ObjectDataSourceView.UpdateMethod method is called. (Dispose is called, only if the business object implements the IDisposable interface.) If the method is a static (Shared in Visual Basic) method, the business object is never created and you cannot handle these events.

If the business object that the System.Web.UI.WebControls.ObjectDataSource object works with implements more than one method or function with the same name (method overloads), the data source control attempts to invoke the correct one according to a set of conditions, including the parameters in the ObjectDataSourceView.UpdateParameters collection. If the parameters in the ObjectDataSourceView.UpdateParameters collection do not match those of the signature of the method specified by the ObjectDataSourceView.UpdateMethod property, the data source throws an exception.

For more information, see ObjectDataSource.UpdateMethod.

The value of the ObjectDataSourceView.UpdateMethod property is stored in view state.
