[flexcoders] Re: Datagrid update woes(blank rows)
ok here goes.
private function resultHandler(evt:ResultEvent):void
{
dataProvider = new ArrayCollection (
ArrayUtil.toArray(evt.result) ); // same as: evt.result.toString();
}
public function sendResultHandler(evt:ResultEvent):void
{
dataProvider.addItem(ArrayUtil.toArray(evt.result));
dataProvider.refresh();
}
first function is called when the app is loaded.
second function is called when i add a new user to the database
Re: [flexcoders] Re: Datagrid update woes(blank rows)
trace the evt.result using the ObjectUtil.toString() (note: you will need to
import mx.utils.ObjectUtil to do this) and lets see what is coming back from
the server. most likely the reason you are getting a blank row is that what
is coming back does not match what the grid is expecting.

[flexcoders] Re: Datagrid update woes(blank rows)
ive done as suggested however i still get a blank row
public function sendResultHandler(evt2:ResultEvent):void
{
var index:int = dg.dataProvider.length;
dg.dataProvider.addItemAt(evt2.result,index);
trace(ObjectUtil.toString(evt2.result) );
dg.dataProvider.refresh();
}
funny thing is that if i do this
public function sendResultHandler(evt2:ResultEvent):void
{
dg. dataProvider = new ArrayCollection (
ArrayUtil.toArray(evt2.result) );
var index:int = dg.dataProvider.length;
dg.dataProvider.addItemAt(evt2.result,index);
trace(ObjectUtil.toString(evt2.result) );
dg.dataProvider.refresh();
}
it correctly populates the datagrid with the correct record so im
assuming that the data being retrieved is correct, so the problem must
be the addItemAt() . im really taking a stab in the dark here but i
really appreciate the help you've given so far.
Re: [flexcoders] Re: Datagrid update woes(blank rows)
OK, I think I see what your problem is. You said that your PHP script returns
this, which is a nested array.
(Array)#0
[0] (Object)#1
BIRTH_DATE = 1985-01-01
EMAIL = [EMAIL PROTECTED]
FIRSTNAME = as
HOUSENO = 40
PHONE =
PHONENO = 1240235402-9
POSTCODE = sdf
STREET = asf
STUDENTNO = 41
SURNAME = ap
TOWN = sdf
It's obvious now that you need to add the first item (which is at the index of
zero), instead of the entire array, to the dataProvider. See the result[0]
below. Hope that makes sense. And just use addItem instead of addItemAt if you
just want to place it at the end of the array.
public function sendResultHandler(evt:ResultEvent):void
{
var row:Array = ArrayUtil.toArray(evt.result[0]);
dataProvider.addItem(row);
dataProvider.refresh();
}
Now you might have to change this line:
var row:Array = ArrayUtil.toArray(evt.result[0]);
to fit exactly what you want. It might work as is though.
Cheers,
Adam

[flexcoders] Re: Datagrid update woes(blank rows)
great news!!...ive gone back to using remotingConnection and your
method worksthank you so much for all your input!
public function onSendResult(result :Array) : void
{
if(!result) return;
dg.dataProvider.addItem(result[0]);
dg.dataProvider.refresh();
}
