ObjectDataSourceMethodEventArgs Class

Provides data for the ObjectDataSource.Inserting, ObjectDataSource.Updating, and ObjectDataSource.Deleting events of the System.Web.UI.WebControls.ObjectDataSource control.

Syntax

public class ObjectDataSourceMethodEventArgs : System.ComponentModel.CancelEventArgs

Remarks

The System.Web.UI.WebControls.ObjectDataSourceMethodEventArgs class is used in the ObjectDataSourceView.OnSelecting(ObjectDataSourceSelectingEventArgs), ObjectDataSourceView.OnUpdating(ObjectDataSourceMethodEventArgs), ObjectDataSourceView.OnInserting(ObjectDataSourceMethodEventArgs), and ObjectDataSourceView.OnDeleting(ObjectDataSourceMethodEventArgs) methods to provide access to input parameters that are passed to the ObjectDataSource.Select, ObjectDataSource.Update, ObjectDataSource.Delete, and ObjectDataSource.Insert methods of the System.Web.UI.WebControls.ObjectDataSource control. These parameters are accessed using the ObjectDataSourceMethodEventArgs.InputParameters property. By adding a delegate to handle the ObjectDataSource.Selecting, ObjectDataSource.Updating, ObjectDataSource.Inserting, or ObjectDataSource.Deleting event, you can examine and manipulate the values of the parameters and perform any additional preprocessing that is required. Any changes to the parameters in this dictionary will affect which method overload is called for the operation. When the ObjectDataSource.DataObjectTypeName property of the System.Web.UI.WebControls.ObjectDataSource control is set, you can only modify the data object properties for the items in this dictionary; you cannot add or remove parameters. For more information, see ObjectDataSource.Delete.

The System.Web.UI.WebControls.ObjectDataSource control exposes many events that you can handle to work with the underlying business object at various times in its life cycle. The following table lists the events and associated EventArgs classes and event handler delegates.
