[flexcoders] DG.dataProvider.length returns 0 at creationComplete time

2007-02-12 Thread Paul Barbieux 
Hello;

I would like that the number of lines in my dataGrid is equal to the
number of data from my dataProvider.

I have found a part of solution by searching in this forum, and the code
is simple:

DG.rowCount = DG.dataProvider.length;

So, I have written this code like this:

mx:DataGrid id=DG dataProvider={myDataProvider}
creationComplete=DG.rowCount=DG.dataProvider.length

But it doesn't work: DG.dataProvider.length return 0.

I have tried with the callLater:

private function resizeDG():void {
var dataLength:String = DG.dataProvider.length;
DG.rowCount = DG.dataProvider.length;
}
mx:DataGrid id=DG dataProvider={myDataProvider}
creationComplete=callLater(resizeDG);

The problem remains...

I have placed the resizeDG function in the creationComplete of the main
component... and the problem remains...

But, if I create a button that calls the resizeDG, yes!, my dataGrid
grows to the correct number of lines !

Thus, my problem is: how to invoke my function when the dataGrid is
displayed ?
Why the creationComplete doesn't work ?...

Thank's

Paul

At your time of creationComplete the dataprovider probably isn't
populated. Thus you want the rowcount to change when the dataprovider
length changes.
 
Try binding the rowCount property of the dataprovider to the
dataprovider like:
 
mx:DataGrid id=DG dataProvider={myDataProvider}
rowCount={myDataProvider.length} /

have you tried using the initialize event?
