I am testing both of this examples, thanks.. Question: is there any possibility to control the DataGrids scrolling thumb position and height?
Because this way a page size would be fixed (rows not scrolling at all) and the scroller would be used just for navigation through pages (instead of the "breadcrumbs" section above the grid). It would also give an info of current page / total pages. It would be nice if the scroller position and height could be set in percentage (e.g. positionFromTop=20, height=10) while the loaded rows count is always equal to grid rows count. --- In flexcoders@yahoogroups.com, "roman_dolgov" <[EMAIL PROTECTED]> wrote: > > I am facing similar problem and wrote a blog entry on similar topic: > http://blog.widget-labs.com/?p=7 > > (The main idea is to implement custom IList data provider that relies > on ItemPendingError for delayed loading) > > regards > rd > > --- In flexcoders@yahoogroups.com, "Danko Kozar" <danko.kozar@> wrote: > > > > I'd like to hear some thoughts about paging implementation on Flex > > DataGrid. > > > > The server side implementation isn't a problem - I have a paging > > routine that fetches chunks of data from a database.
