The mouseDown/getURL portion is just the change event of the
datagrid.
<mx:DataGrid change="onRowSelected(event.target.selectedItem)" />
The onRowSelected(row) function could then just call getURL with
some property of the row data, e.g. row.url. Just be sure to verify
the row parameter first, since you will also get the change event if
the user de-selects the row by ctrl-clicking.
