I actually tried this (my dataProvider for the grid is an XMLListCollection being populated by a jsp. The grid has custom item renderers if that's relevant).
anyhow, I have an "update" button which will call the jsp and get new results when clicked. I've set it up so the click() method correctly captures the scroll position, calls the jsp, and then sets the scrollToIndex to the previous value of the scroll position. It works great while the "busy cursor" is displayed, but it reverts back to scrolled all the way at the top once the actual data comes in from the jsp (it takes about 3 seconds to update the grid with the new data). any ideas on where the scroll position is being reset? --- In flexcoders@yahoogroups.com, "Deepa Subramaniam" <[EMAIL PROTECTED]> wrote: > > Hi Jordan - > > > > You can keep track of the verticalScrollPosition property in your > DataGrid and upon receving UPDATES, re-set the verticalScrollPosition to > the previous value and the DataGrid will jump to the last scroll > position and show the correct content. > > > > -deepa > > > > ________________________________ > > From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On > Behalf Of Jordan Snyder > Sent: Monday, June 26, 2006 7:34 PM > To: flexcoders@yahoogroups.com > Subject: [flexcoders] Keeping DataGrid from scrolling to top on update > to dataProvider > > > > Hello All, > > I am working on an app in which I poll the server quite frequently to > get new information.
