	CanPage	Gets a value that indicates whether the EntityDataSourceView object that is associated with the current EntityDataSource control supports paging of retrieved data.(Overrides DataSourceView.CanPage.)
	CanRetrieveTotalRowCount	Gets a value that indicates whether the EntityDataSourceView object that is associated with the current EntityDataSource control supports retrieving the total number of data rows, in addition to retrieving the data.(Overrides DataSourceView.CanRetrieveTotalRowCount.)
	CanSort	Gets a value that indicates whether the EntityDataSourceView object that is associated with the current EntityDataSource control supports a sorted view of the retrieved data.(Overrides DataSourceView.CanSort.)
	CanUpdate	Gets a value that indicates whether the EntityDataSourceView object that is associated with the current EntityDataSource control supports the update operation.(Overrides DataSourceView.CanUpdate.)
	Events	Gets a list of event-handler delegates for the data source view.(Inherited from DataSourceView.)
