How to prevent a flex datagrid from scrolling up when setting dataprovider?

var scrollPos:int = myGird.verticalScrollPosition;
myGrid.dataProvider = updatedDataProvider;
myGrid.verticalScrollPosition = scrollPos;

Dropdown on a ComboBox not updating when changing dataProvider

[yourCombo].dataProvider = yourDataProvider; is not updating the dropdowns?

Try,
[yourCombo].dataProvider = yourDataProvider;
[yourCombo].dropdown.dataProvider = [yourCombo].dataProvider;

It should happen internally but bad bad SDK!
