RE: [flexcoders] ComboBox in Component won't open to Saved Value
Here's the code for a BindableComboBox. Save it in a file called
BindableComboBox.mxml (borrowed this code from Adobe, modified slightly):
mx:ComboBox xmlns:mx=http://www.adobe.com/2006/mxml;
creationComplete=initComponent()
mx:Script
![CDATA[
import mx.utils.ObjectUtil;
import mx.controls.Alert;
[Bindable] public var valueField:String = ;
[Bindable] public var labelFields:Array = [];
public function initComponent():void {
this.labelFunction = renderLabelFunction;
}
public function renderLabelFunction(item:Object):String {
var result:String = ;
if (labelFields.length == 0) {
if (labelField != null) {
return item[labelField];
}
else {
return item.toString();
}
}
else {
for (var i:int=0; i labelFields.length; i++) {
if (i 0) {
result += ;
}
result += item[labelFields[i]];
}
}
return result;
}
override public function set selectedItem(val:Object):void {
if (this.valueField != null) {
for (var i:int=0; i this.dataProvider.source.length; i++) {
var item:Object = this.dataProvider.source[i];
if (item[valueField] == val) {
this.selectedIndex = i;
break;
}
}
}
else {
super.selectedItem(val);
}
}
public function get selectedItemValue():Object {
if (this.valueField != null selectedItem != null) {
return selectedItem[valueField];
}
else {
return text;
}
}
]]
/mx:Script
/mx:ComboBox
Use it in your components as follows:
Get the data back from the database (or webservice, or wherever) into an
ArrayCollection that has the fields myID and myName for each item in the
combo box. Then, assign the AC to the dataProvider of the BindableComboBox
and use the component in your mxml code like this:
mycoms:BindableComboBox id=myComboBox valueField=myID
labelFields=[myName]/
I also have a search-as-you-type BindableComboBox that's a combination of
this component with an auto-complete component I found on the web (not
Adobe's) if you're interested.

ComboBox.selectedItem will only work if you assign a *reference to an item
in the ComboBox dataProvider*. This is rarely possible and is not in your
case.
What you must do is loop over the items in the CobmoBox.dataProvider and
compare the appropriate property's value to the value you want to match.
When a match is found, use the loop indes to set the ComboBox's
selectedIndex. This is simple enough to do in a one-off situation.
If you need this often, then you might want to use an extended ComboBox.
Making a generic one is a bit tricky, because the Combo Box dataProvider
items can have any properties at all. I have an example on www.cflex.net
http://www.cflex.net/ (it allows you to set the data field you want to
match) and Ben forta has done one and there are others.

Hi
I have a ComboBox used as a Popup on a form component.
It saves fine using the following function
private function closeGenderPop(event:Event):void {
ComboBox(event.target).selectedItem.label};
I want to have it display the stored value the next time it is opened.
I tried this but no luck.
private function openGenderPop(event:Event):void {

Thanks for the response. I understand what needs to be done as you described
but I still have one problem.
I tried this before.
private function openGenderPop(event:Event):void {
genderPop.selectedIndex = 1;
}
The ComboBox opened to the zero value not the 1.
When I clicked on the box it opened to have the 1 value preselectect but did
not present upon opening.
I am referencing it like this and must be missing some kind of kick event?
mx:ComboBox id=genderPop close=closeGenderPop(event)
open=openGenderPop(event) dataProvider={arrGender} x=583.5 y=89

Why are you doing that in the open event? Try creationComplete
instead. Or set it directly without the function. Or bind
selectedIndex to a bindable variable.

RE: [flexcoders] ComboBox in Component won't open to Saved Value
This seems absurdly difficult for so simple a function.
I am trying to save a value from a popup and get it back when the list is
double clicked and the form is represented with a different record selected.
Not exactly rocket science.
I have tried every single event and nada.
Is there an on Load Why not? It seems so obvious.
Creation complete only works the first time the form component is presented.
The functions are
private function closeRolePop(event:Event):void {
ComboBox(event.target).selectedItem.label};
private function openRolePop(event:Event):void {
var i:uint;
for(i=0; i arrRoles.length; i++){
if(arrRoles.getItemAt(i).label == currentPerson.Role){
rolePop.selectedIndex = i;
}}}
Help Please this is really getting to me cause it should be so simple

Subject: [flexcoders] ComboBox in Component
won't
open
to Saved Value
Hi
I have a ComboBox used as a Popup on a form
component.
It saves fine using the following function
private function closeGenderPop(event:Event):void
{
ComboBox(event.target).selectedItem.label};
I want to have it display the stored value the
next
time it
is opened.
I tried this but no luck.
private function openGenderPop(event:Event
RE: [flexcoders] ComboBox in Component won't open to Saved Value
The Combobox by itself does not really support what you're trying to do.
As Tracy said there is sample code you can draw on to extend the
ComboBox to accept a 'selectedValue' parameter or something of the sort,
which in turn will fire internal logic to determine which item in the
dataProvider matches and to set the selectedIndex accordingly.
The other part of this is using binding. To have your instantiated
combobox to update its selectedIndex when a value changes you need to
reference a bindable value. If another code alters that value, it will
then re-fire the internal logic in your custom ComboBox.
{Bindable]
private var dp:Array =
[{data:'foo',label:'foo'},{data:'foo1',label:'foo1'},{data:'foo2',label:
'foo2'}];
[Bindable]
private var myVal:String = foo;
local:CustomComboBox dataProvider={dp} selectedValue={myVal}/

This seems absurdly difficult for so simple a function.
I am trying to save a value from a popup and get it back when the list
is double clicked and the form is represented with a different record
selected. Not exactly rocket science.
I have tried every single event and nada.
Is there an on Load Why not? It seems so obvious. Creation
complete only works the first time the form component is presented.
The functions are
private function closeRolePop(event:Event):void {
ComboBox(event.target).selectedItem.label};
private function openRolePop(event:Event):void {
var i:uint;
for(i=0; i arrRoles.length; i++){
if(arrRoles.getItemAt(i).label == currentPerson.Role){
rolePop.selectedIndex = i;
}}}
Help Please this is really getting to me cause it should be so simple

Creation complete works the first time but the component is
displayed when you click on a list, and subsequent
selections are not displayed. I am having trouble figuring
out which on is the correct event.?
Sorry but I am relatively new at this kind of programming.
Thanks

Why are you doing that in the open event?
Try
creationComplete
instead. Or set it directly without the function. Or
bind
selectedIndex to a bindable variable.

Thanks for the response. I understand what needs to be
done
as you
described but I still have one problem.
I tried this before.
private function openGenderPop(event:Event):void {
genderPop.selectedIndex = 1; }
The ComboBox opened to the zero value not the 1.
When I clicked on the box it opened to have the 1
value
preselectect but
did not present upon opening.
I am referencing it like this and must be missing some
kind
of kick
event?
mx:ComboBox id=genderPop
close=closeGenderPop(event)
open=openGenderPop(event)
dataProvider={arrGender}
x=583.5
y=89
width=116 /
Thanks again.
This board is GREAT !

will only work if you
assign a
*reference to an
item in the ComboBox dataProvider*. This is
rarely
possible and is not
in your case.
What you must do is loop over the items in the
CobmoBox.dataProvider and compare the appropriate property's value
to
the
value
you want to match.
When a match is found, use the loop indes to set
the
ComboBox's
selectedIndex. This is simple enough to do in a
one-off
situation.
If you need this often, then you might want to
use an
extended ComboBox.
Making a generic one is a bit tricky, because the
Combo Box
dataProvider
RE: [flexcoders] ComboBox in Component won't open to Saved Value
Am I going down the wrong road with ComboBox?
Geez I can set a popup and get the value back with Php or any of a number of
other languages.
Seems REALLY absurd that this is this difficult.
Dan
P.S. Where do I get the custom combobox code? or will the binding approach work
with a regular out of the box combobox?
thanks for you time.

Are you telling me that there is no simply way to have a user pick a value from
a popup then redisplay that value in the popup if he goes back to the record
again later?
Is this a joke or a programing language?
Somebody forgot to include an event that says if this record has a value show
it in the popup?
No you got to be pulling my chain. If you are not then this is a useless joke.
Its an everyday need.

RE: [flexcoders] ComboBox in Component won't open to Saved Value
Depends on what you mean by simple. It will just take a few lines of
code.
The difficulty lies in knowing which lines.
Going ballistic in frustration is never helpful.
Take this one step at a time. Make sure you can call your function when
the pop-up opens. Make sure you have the value you want to set the
combo box to at that point.
You have not shown us much code, so we can't really say what is wrong.
