You can examine the System.Web.UI.DataSourceSelectArguments object to determine whether sorting, paging, or a row count are requested as part of the data retrieval operation.

Data-bound controls use the System.Web.UI.DataSourceSelectArguments class to request that the System.Web.UI.WebControls.SqlDataSource perform additional data-related operations on a result set, such as sorting the data or returning a specific subset of data. These data-related operations are enumerated by the System.Web.UI.DataSourceCapabilities enumeration. For more information, see System.Web.UI.DataSourceSelectArguments.
