ObjectDataSourceView.Selecting Event

Occurs before a data retrieval operation.

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

public event ObjectDataSourceSelectingEventHandler Selecting

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 ObjectDataSource control performs the data retrieval operation. The parameters are available as an IDictionary collection that is accessed by the InputParameters property, which is exposed by the ObjectDataSourceMethodEventArgs object.
