Data-bound controls use the System.Web.UI.DataSourceSelectArguments class to request that the System.Web.UI.WebControls.ObjectDataSource object perform additional data-related operations on a results 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. The ObjectDataSourceSelectingEventArgs.Arguments property is read-only, so you can examine, but not change, the arguments that are passed by the data-bound control. For more information, see System.Web.UI.DataSourceSelectArguments.
