The System.Web.UI.DataSourceOperation enumeration represents the actions that a data source control can perform on its underlying data. Data source controls such as System.Web.UI.WebControls.SqlDataSource and System.Web.UI.WebControls.ObjectDataSource use these enumeration values to track the type of operation being performed.
The five major data source operations are represented by the System.Web.UI.DataSourceOperation enumeration. The DataSourceOperation.Select and DataSourceOperation.SelectCount values indicate operations that retrieve data from an underlying data source, while the DataSourceOperation.Delete, DataSourceOperation.Insert, and DataSourceOperation.Update values indicate operations that modify data.
