I don't know if this is the most elegant solution, but it worked
somewhat.
I still think there must be a way for the underlying dataProvider to
change without triggering a redraw of all the scrollbar navigation
elements. I thought I read somewhere that you can turn off the redraw
on update to a data component, but I can't seem to locate that
property again.
anyway, until I find it, here is my solution:
DEFINE A VARIABLE TO HOLD THE CURRENT SCROLL POSITION
public var userScrollPos:Number;
ASSIGN FUNCTIONS TO THE DATAGRID EVENTS
//this will initiate the database update when item editing is done
itemEditEnd="updateDataField(event)"
IN THE updateDataField FUNCTION SAVE THE CURRENT SCROLL POSITION
userScrollPos = dgDisplay.verticalScrollPosition;
//this will restore the scroll position when the dataProvider update
is complete
updateComplete="restorePos()"
ON THE updateComplete EVENT RETORE THE SCROLL POSITION
public function restorePos(){
dgDisplay.verticalScrollPosition = userScrollPos;
}
If anyone finds a better way to do this, please let me know.
Thanks, Kevin

this in use? The usual properties & methods i am used to don't
exist any more!
thanks, Kevin

I think you’ll just have to record the selectedIndex in a variable
and then set selectedIndex = that variable after data reload.

Subject: [flexcoders] DataProviders & DataGrid Scroll Locations
Is there a way to update a DataProvider while keeping the scroll
location of the DataGrid that it binds to. Everytime I reload the
data provider, the scroll location goes back up to the first item.
