Remarks

Data source controls use the DataSourceCapabilities enumeration in conjunction with the DataSourceSelectArguments class to request paging, sorting, or other select-specific capabilities when performing a data retrieval operation. The requested capabilities are checked against the actual capabilities of the data source control during the data retrieval operation, and if they do not match an exception is raised.

This enumeration supports the FlagsAttribute attribute, which enables you to use more than one member at a time.
