Remarks

The PagedDataSource class encapsulates the properties that allow data-source controls, such as the DataGrid, GridView, DetailsView, and FormView, to perform paging. This class is used by control developers when providing paging support to a custom data-bound control.

This class uses the best available method to enumerate over the data belonging to the current page. If the underlying data source supports indexed access (such as System.Array and System.Collections.IList), this class uses it. Otherwise, it uses the enumerator created by the GetEnumerator method.

For a list of initial property values for an instance of PagedDataSource, see the PagedDataSource constructor.
