Re: [flexcoders] DataGrid.labelFunction
This works, but my code in my main app doesn't work... imagine that

I cannot get this to work.
I've tried:
my_datagrid.labelFunction = Delegate.create(this, onMyLabelFunction);
my_datagrid.labelFunction = onMyLabelFunction;
As well as through the attribute in the datagrid tag:
mx:DataGrid labelFunction=onMyLabelFunction
I can trace out that it's actually setting the value to a valid function
through the debugger and me tracing out the values to a TextArea, but that
same debugging session shows the actual function itself never getting run.
I've tried setting the dataProviders right after, 1 frame after, and even 2
frames after via multiple doLaters.
I've tried setting the ViewStack hosting this component to to auto
creationLayout instead of all, and used childrenCreated to defer the actual
setup.
Nothing works.

RE: [flexcoders] DataGrid.labelFunction
Maybe the signature of your function is
not the right one, try using :
private function onMyLabelFunction (item , columnName) : String {

Re: [flexcoders] DataGrid.labelFunction
Just a guess looking at the Flash code (if someone
could confirm in the REAL Flex classes which I haven't got).
- it seems mx.controls.listclasses.SelectableRow
has it's owner property set when it's created to know scope. This scope is
used to call labelFunction.
- SelectableRow is the default cellRenderer for
ScrollSelect list, which DataGrid extends. SelectableRow creates rows
using ScrollSelectList by default for the cellRenderer, which he sets the owner to this, the DataGrid
- since the DataGrid's labelFunction property is
already set, when the SelectableRow is looking for a label, and calls
labelFunction on the DataGrid, it's really doing:
theDataGrid.labelFunction(object)
Now, since Flex changes this, so for DataGrids you
also get the columnName, I'm thinking that change might of not been tested
heavily with DataGrids in ViewStacks.
Either that, or I'm missing something horribly
obvious.
Anyone have a
mx.controls.listclasses.SelectableRow.as file to send me for Flex so I can
see?
