Devin created FLEX-34761:
----------------------------
Summary: DataGrid DragScoll does not work if you disable dropping
and call hideDropIndicator on some rows.
Key: FLEX-34761
URL: https://issues.apache.org/jira/browse/FLEX-34761
Project: Apache Flex
Issue Type: Bug
Components: Spark: DataGrid
Reporter: Devin
The DataGrid's dragscroll behavior is kicked off from within the
showDropIndicator() method. It's common to handle/override the dragOverHandler
to only allow dropping on certain rows. If you have the rows at the bottom of
the scroll window configured to not allow dropping, you would also want to call
hideDropIndicator() for those rows. But by doing so, you've also disabled the
dragScrolling behavoir.
The dragScrolling behavior should be functional by the drop target calls
DragManager.acceptDragDrop() from the dragEnterHandler(). It should not be
tied directly to the showDropIndicator() method.
