Hello,

I'm facing to this issue and looking for quick patch. I'm in 4.11 Flex SDK and Items dropped to a datagrid (same result for grid to another grid or inside the same grid) always go to the 2nd position and no drop indicator into datagrid. I need this functionality to manually order datagrid items by drag and drop.
Is there no solution other then recompile the SDK?
Maybe you can help me by sending a patch or quick tip? 

Thank you

>             Project: Apache Flex
>          Issue Type: Bug
>          Components: Spark: DataGrid
>    Affects Versions: Apache Flex 4.14.0
>            Reporter: Devin
>              Labels: drag&drop
>
> Description
> Dropping a dragged item onto the grid does not work. When calculating the DropLocation (in dragEnter, dragOver, dragDrop handlers) it falls through to LayoutBase.calculateDropIndex which simply executes "return target.numElements;" That's clearly not how the dropIndex should be calculated on the grid. The GridLayout class should be overriding this method and calculating it correctly.
> Furthermore, upon trying to fix this issue (which is more complicated than it should be because DataGrid.calculateDropPosition() is marked as private) the DataGrid.calculateDropPosition() does not perform a null check on the DropLocation (which is valid value).
> Steps to Reproduce
> 1. Create a DataGrid with dragEnabled, dragMoveEnabled, and dropEnabled all set to true.
> 2. Try dragging rows around and dropping them.
> Environment
> Windows 8, Apache Flex 4.14
> Expected Behavior
> Seeing the drop indicator.
> The expected behavior of dragging a row and dropping it in another location.
> Actual Behavior
> No drop indicator. Dropping a row does nothing.
