Amy is saying you could write your function like this:

private function labelFunctionTest( itm:Object, col:DataGridColumn) :String 
{
return df.format(itm[ col.dataField] );
}

Which is correct and probably the easiest way to go.  If you want to subclass 
you would do something like this:

 public class AngeloDataGridColum n extends DataGridColumn
 {
 public function AngeloDataGridColum n()
 {
 labelFunction = labelFunctionTest;
 }

 private function labelFunctionTest( item:Object, col:DataGridColumn) 
:String
 {
 return owner.document. df.format( item[dataField] );
 }
 }

By subclassing you don’t have to assign the labelFunctions to the columns that 
need them.

If it were me, I would subclass DataGridColumn and add the labelfunction to

 That is what the DataGridColumn parameter is for. Look at its dataField

Re: [flexcoders] Re: Reuse a LabelFunction

2010-03-17 Thread Angelo Anolin 
Ho would I be able to specify other dataField based from your example?

Say in my datagrid, col1's datafield is COL1 and col2 is COL2.

Using the label function, I need to fully qualify the datafield name like:

df.format(item[col.COL1])

which in turn I could only use for COL1.

Since I have some datagrid where the same date formatting can be used, then 
perhaps re-using the same label function would be of good help.

Thanks.

I do know a bit of using itemrenderer.. Inline that is.. 

if you could post some example, I'd greatly appreciate it.

would the itemrenderer be an as file or would it be inline as well?

Thanks.
