Occurs before a data retrieval operation.
Assembly: System.Web (in System.Web.dll)
Handle the 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.
