public class SqlDataSourceStatusEventArgs : EventArgs

System_CAPS_pubmethodSqlDataSourceStatusEventArgs(DbCommand, Int32, Exception)

Initializes a new instance of the SqlDataSourceStatusEventArgs class, using the specified output parameters, return value, and number of rows affected by the database operation.


Gets the number of rows affected by a database operation.


Gets the database command submitted to the database.


Gets a wrapper for any exceptions thrown by the database during a data operation.


Gets or sets a value indicating whether an exception thrown by the database has been handled.


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

The SqlDataSourceStatusEventArgs class is used in the Selected, Updated, Inserted, and Deleted events to pass information about a database operation after it is performed by the data source control. This information includes the number of rows affected by the operation, the DbCommand object that the data source used to perform the operation, and any exception information that resulted. By adding an event handler delegate to handle the Selected, Updated, Inserted or Deleted events, you can examine this data and perform any additional post processing required.

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 life cycle of a data operation using the SqlDataSource control.




Selecting occurs before the data is retrieved.



Inserting, Updating, Deleting occur before an insert, update, or delete operation is performed.



Selected, Inserted, Updated, Deleted occur after the data retrieval, insert, update, or delete operations completes.



The following code example demonstrates how to use the SqlDataSourceStatusEventArgs class to examine the return value and values of output parameters that are returned when using a SqlDataSource control with a stored procedure to populate a GridView control. The stored procedure selects data that is displayed in the GridView, but also passes other information back to the caller, such as an integer output parameter and a return value. The parameters that the SqlDataSource uses for the stored procedure are contained by the SelectParameters collection, and consist of parameters that pass information from the Web form to the stored procedure as well as parameters that pass information back to the form. The Direction property of these parameters is set to Output and ReturnValue.
