SqlDataSource.Selecting Event

Occurs before a data retrieval operation.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public event SqlDataSourceSelectingEventHandler Selecting
/** @event */
public void add_Selecting (SqlDataSourceSelectingEventHandler value)

/** @event */
public void remove_Selecting (SqlDataSourceSelectingEventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

Handle the Selecting event to perform additional initialization operations that are specific to your application, to validate the values of parameters, or to change the parameter values before the SqlDataSource control performs the select operation. The select arguments are available from the SqlDataSourceSelectingEventArgs object that is associated with the event.

For more information about handling events, see Consuming Events.
