Handle the ObjectDataSource.Updating event to perform additional initialization that is specific to your application, to validate the values of parameters, or to change the parameter values before the System.Web.UI.WebControls.ObjectDataSource control performs the update operation. The parameters are available as an IDictionary collection that is accessed by the ObjectDataSourceMethodEventArgs.InputParameters property, which is exposed by the System.Web.UI.WebControls.ObjectDataSourceMethodEventArgs object.
