Combobox in Datagrid with different values

Question

Hi All,
I have a datagrid. One of the columns in the datagrid is set
to display a combobox as the ItemRenderer. Now, the data for the
combobox is different for each row. How do I set up the data
provider for the combobox in such a scenario.
For example : I have a collection of Shirt objects.
public class Shirt {
public String id;
public String type;
public String[] color; //this is an array
This should be displayed in the datagrid, with the Color
column rendered as a combobox. The colors will be different for
each shirt.
Thanks

Yes. Some more detail:
in the function,
override public function set data(value:Object): void {
the "value" parameter will contain a refernce to an entire
"Shirt" instance.
So you can assign the comboBox.dataProvider=value.color;
Now, It is more complicated than this, because you will want
the combobox to show the correct value for each row, right?
For this to happen, you will need a selectedColor property on
Shirt. When the user chooses a color, you will need to update this
property with the selection.
Next, your renderer must read the value of selectedColor and
set the comboBox.selectedIndex.
If selectedColor contains the *index* of the color then you
have it easy. If it contains the color name itself, then you will
have to for-loop over the color array until yom match the
selectedColor. then you will have the index and can set
selectedIndex.
ComboBox does not support setting the value directly. It is
pretty easy to extend combo to do this. There are several examples
out there. I posted a link to one on CFLEX.net
