Flashcoders doesn't seem to be responding, so I hope it's OK to ask
here:
I'm using the CellRenderer API with a datagrid for the first time. It's
working great, I'm adding checkboxes to cells in the datagrid.
However, in my class CheckBoxCell which extends mx.core.UIComponent, I
added some code to the inherited setValue method:
function setValue(str:String, item:Object, sel:Boolean) : Void
{
cb._visible = (item!=undefined);
if(item[getDataLabel()] == "Y") { cb.selected = true }
else { cb.selected = false };
}
This works fine to make all my checkboxes checked or not checked if the
item's data in dataprovider is Y or N, but it also causes some odd
behaviour in that the checkbox, after clicked by the user, will revert
back to it's original dataprovider value. I think I understand why, as
the datagrid keeps it's children rendered to it's set dataprovider
values, but I'm not sure what to do about it. Do I need to change the
dataprovider values first? If so, how from within the CheckBoxCell
class? Or how do you normally handle this?
Thanks,
