Re: [flexcoders] Re: Flex2 Beta2 - Looping through dataGrid to bold cells
hi Ryan,
the best way I can come with now is :
1. in your item renderer's constructor, listens to "dataChange" event,
whenever list-based comonents redraws itself, the "data" property
inside each item renderer will be called, hence trigger the
"dataChange" event.
2. by listening to "dataChange" event, you can check the value inside
the VO or object passed in, then let item renderer do the job (bold or
un-bold a text or anything else).
there's a well-written chapter in manual about data getter/setter and dataChange event, search for it.

RE: [flexcoders] Re: Flex2 Beta2 - Looping through dataGrid to bold cells
So you want all data in the grid to be bold? Then you should be able to
just set the style on the grid instead of setting it on each row.
As for cell renderers, yes yes and yes. It renders on a cell basis and
can modify the display based on the data returned for that cell. And you
can include pictures if you want to! You can create child objects of any
type (I assume there are some objects that grid cells do not support
though).
The best way to start is to pull up the much used check cell renderer.
It displays a checkbox for each cell and checks/unchecks based on a
conditional of the data returned for that cell. Once you have the cell
renderer class done, just set the cellRenderer property on your
dataColumn to be your new class.

Hey Karl, thanks for the quick response!
Ideally, I'd like certain rows to be bold when the data is populated,
but I don't know how to do that. So, I'd like to bold the cells as soon
as the data is displayed. I never want the user to see the data in the
dataGrid without the bold text.
I'm really curious about this custom cell renderer. Can it go to the
cell level, or just row? Can I include pictures??? Can all this be
done on a conditional basis (the value of the cell)?
I can't find a Beta2 link for it, everything is Beta1, except for

RE: [flexcoders] Re: Flex2 Beta2 - Looping through dataGrid to bold cells
Yes, a cellrenderer is on the cell level. Yes, you can include any other
component you like (image or otherwise). Yes, it can very easily be done on
a conditional basis.
Bold text, red text, what ever you heart desires. :)

Hey Karl, thanks for the quick response!
Ideally, I'd like certain rows to be bold when the data is populated,
but I don't know how to do that. So, I'd like to bold the cells as
soon as the data is displayed. I never want the user to see the data
in the dataGrid without the bold text.
I'm really curious about this custom cell renderer. Can it go to the
cell level, or just row? Can I include pictures??? Can all this be
done on a conditional basis (the value of the cell)?
