well, the origional post went down like a lead dirigeable.... I'll
back up a bit and try to explain better...
I have query data that I want to edit in a datagrid, mostly to utilise
the textbox-type features. However...
two columns are look-up data, best represented by ComboBox's. it looks
like I can use itemRenderers for the cells in these columns. What I'm
stuck on is the best way to bind the look-up data to the ComboBox's
when they're used as itemRenderers.
because I want to extend the ComboBox's anyway, I could (in theory)
have these as custom components and bind the dynamic data directly to
each within the custom control mxml - hard wired in. but If I want to
use the same control for both columns but with different data, I'm
stuck
is there any way of keeping the custom controls "dumb" and, from the
datagrid's level, tell the itemRenderers what look-up data model to
bind to?
something like this:
<mx:DataGridColumn headerText="Role"
itemRenderer="custom_controls.ComboBox" rendererDataProvider="{colRole}"/>
<mx:DataGridColumn headerText="Type"
itemRenderer="custom_controls.ComboBox" rendereDataProvider="{colEvalType}"/>
is (something like) this possible? is there a better way?
How can comboBoxes with dynamic data be integrated with DataGrids?
any suggestions most welcome.
thanx

PS: I suspect that this is only half the battle. Getting the DataGrids
data model to store the ComboBox selection might be the other half...
