Hi Yu,
Can you give more information about your use case? Why are you wanting to build a navigation bar from a table view?

Hey Yu,
unless I'm mistaken, the pagination is intended to be shown on browsers without JavaScript/Ajax. In the other case, the data is partially loaded, and updates as the user scrolls through the WTableView.

SELECT * FROM tuser WHERE conditions LIMIT ${iRows} OFFSET (${iPage}-1)*${iRows}

Hi,
That is pretty much what Wt::Dbo::QueryModel< Result > does: as data is queried, it fetches other parts of the query result. This works nicely in the design of WTableView, that will only query the model for data for the visible rows (plus a little margin).
Wim.
