Because the class is derived from the CancelEventArgs class, you can cancel a pending SqlDataSource database command by setting the Cancel property to true. You can examine and manipulate the CommandText, Parameters collection, and other command properties prior to running the command by accessing the DbCommand object exposed by the Command property.
The class is used in the OnUpdating, OnInserting, and OnDeleting methods to provide access to a SqlDataSource database command before it is run. The SqlDataSource control exposes many events that you can handle to work with the underlying data objects during the course of a data operation. The following table lists the events and associated EventArgs and event handler classes, to better guide you to the various events that correspond to the lifecycle of a data operation using the SqlDataSource control.
Selecting occurs before the data is retrieved.
The following code example demonstrates how to display data retrieved from a Microsoft SQL Server database in a DropDownList control, and update the record using a TextBox control. The example shows how you can use a DbTransaction object to add transaction context when using the SqlDataSource control to update data.
