>          Issue Type: New Feature
>          Components: .Unspecified - Mobile
>    Affects Versions: Apache Flex 4.11.0
>            Reporter: Maurice Amsellem
>              Labels: datagrid, mobile
> I have developed for my company (SYSTAR) a custom Flex Mobile DataGrid component (MDG
for short) , for one of our projects (Business Activity Monitoring framework, running on mobile
devices ).
> You can see a quick video of the MDG in action here:

> More details on the component at end of this email.
> I would like, on behalf and with  the formal agreement of my company, to donate this
component's source code to Apache Flex.

> Mobile DataGrid component details:
> The goal was to provide essential datagrid functions adapted to mobile devices, with
good performance on mobile.
> Features:
> -          Displays information in tabbed columns (like any datagrid)
> -          Sorting columns by clicking on the header
> -          Touch enabled scrolling.
> -          Selection
> -          Default renderers for stylable text and embedded bitmaps.
> -          Custom renderers (preferably in AS) are possible.
> -          Multi DPI aware ( both scaling and no scaling, media css, multi-DPI artwork).
> *Note on performance*
> Good performance was key for this component, so it derives from List, and not from DataGrid.
> To ensure good performance, all the columns for each row are rendered using one single
"TabbedRowItemRenderer" which inherits from the base mobile list renderer.
> This renderer will delegate the rendering of each column in the row to  lightweight sub-renderers,
and will manage the tabbed layout of sub-renderers.
> There are two predefined sub-renderers:
> - The sub-renderer for Text inherits from StylableTextField
> - The sub-renderer for bitmaps inherits from BitmapAsset.
> Custom sub-renderers must implement a given interface and be written in AS3.
> Performance tests:
> Sample Mobile dataGrid displaying: 300 lines by 6 columns:
> . 4 of small text,
> . 1 with icon
> . 1 with  multiline very long text in small font.
