BERTOLINO commented on FLEX-34741:
----------------------------------
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. 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
> Spark DataGrid Drag and Drop non functioning
> --------------------------------------------

> Key: FLEX-34741
> URL: https://issues.apache.org/jira/browse/FLEX-34741
> 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.
