TcxCustomNavigatorButtons.NextPage Property

A button that scrolls the dataset one page forward relative to the active record.

Declaration

property NextPage: TcxNavigatorButton index NBDI_NEXTPAGE read; write;

Property Value

Type
TcxNavigatorButton

Remarks

This button also posts all changes. If the cursor is moved to the last record, the Last, Next, and NextPage buttons are disabled.

The term “page” means a set of records to move by. A programmer can specify the number of records via the PageSize property. For a data-aware navigator, the page size is determined by the number of records in the internal cache. Most datasets (except for unidirectional ones) maintain an internal cache of records from the underlying database tables. For instance, if the dataset is used to populate a data-aware grid, the cache includes a record for each visible row in the grid.

For an unbound navigator, the page size must be determined by the IcxNavigator implemented in the external control.

For instance, the page size in the ExpressQuantumGrid is specified by the number of visible records.

The default index of this button in the collection is NBDI_NEXTPAGE.
