Re: [Junk E-Mail - MED] Re: [flexcoders] Re: A DataGrid with selectable *cells*

[Anatole Tartakovsky]

Hi Tom,
   I think you can use "runtime datagrid styles" to accomplish that. The technique is one of Advanced DataGrid... described in october- december ( some of it may be not published yet ) issues of Web 2.0 magazine/chapter 11 of our Flex 2 book . The running samples from the articles are available here 
http://samples.faratasystems.com/AdvancedDataGrid/index.html- along with source (right mouse on the index page only).
You basically add "selection" column to each row and use the backgroundColor method to "indexOf" current column name  in selection one.
 
Hope this helps,
Anatole Tartakovsky

Him Tom,as long as your item renderer implements the IDropInListItemRendererinterface you can get the columnIndex and rowIndex from the listDataproperty. If an item renderer lives inside a DataGrid, listData is of
type mx.controls.dataGridClasses.DataGridListData - so everything shouldbe there already.Dirk.> -----Original Message-----> From:
