So the idea is to create the DG one row taller than the VBox, put it in the VBox and move the DG until you have moved an entire row, then move the DG back and actually scroll it one row.

I was thinking of removing the datagrid, instead creating a Vbox and then populating it with hbox which will represent the row and then creating a canvas of the size of a single hbox, but what if there are many records in the dataprovider ? ----- Original Message ---- From: Alex Harui <[EMAIL PROTECTED]> To: [email protected] Sent: Tuesday, December 12, 2006 12:16:35 AM Subject: RE: [flexcomponents] how I can scroll the datagrid automatically ? Changing the DataProvider is expensive. You should only do it if the entire data set is in-fact changing (new query or something). Otherwise it is better to modify a single dataprovider. Then, if there multiple rows in the dataprovider, you can scroll using verticalScrollPosit ion. The DG only scrolls by row. If you need pixel-level scrolling, I have suggested that you put the DG in a Canvas and scroll the DG in the canvas. Not sure if anyone has made this work yet. -Alex ________________________________ From: flexcomponents@ yahoogroups. com [mailto:flexcompone [EMAIL PROTECTED] com] On Behalf Of arpan srivastava Sent: Monday, December 11, 2006 5:52 AM To: Flex Components Subject: [flexcomponents] how I can scroll the datagrid automatically ? Hi all, I have to create a datagrid with one row and row will scroll automatically and display data one by one, that is like a ticker. now i what i did is created a timer in which i am changing the datatprovider after certain time interval : private function timerEvent(event: TimerEvent) :void{ if(dataCount < dataProvider. length){ dG.dataProvider = dataProvider[ dataCount+ +]; }else{ dataCount = 0; } dGinvalidateDisplay List(); } it's working fine, but i need to smooth scrolling. is there anyway I can scroll the datagrid automatically. Is there any other way I can do this ? ________________________________ Access over 1 million songs - Yahoo!
