TcxDBNavigatorButtons.PageSize Property

Sets the number of records to be represented on one “page”.

Declaration

property PageSize: Integer read; write; default 0;

Property Value

Type	Default
Integer	0

Remarks

NextPage and PriorPage navigator buttons are used to move a data source cursor by a set of records forward or backward. This set is called a “page” in terms of the navigator control.

Use the PageSize property to specify the number of records in this set.

If you do not specify a number of records using this property (the default value is set to 0), the page size is determined automatically.

All datasets use a number of records in an internal cache set via the BufferCount property as the page size. If the dataset is used to populate a data-aware grid, the cache includes a record for each visible row in the grid.

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

For a non-db navigator, the page size is determined by an external control’s IcxNavigator implementation.

The default value of the PageSize property is 0.
