Flex :: Data Binding - ComboBox And XML List

Mar 19, 2011

I have a bit of a problem (since I'm not used to binding with AS3), the thing is that I want to do this kind of data binding:

<mx:Application xmlns:mx="[URL]"
layout="vertical"
verticalAlign="middle"
backgroundColor="white">
[Code] .....

But the ComboBoxes are being created dynamically with AS3, everything is working except I cant bind the second ComboBox dataProvider to be the XMLList in the first ComboBox's selectedItem.

Flex :: Data Binding - How To Adjust ComboBox Width

Sep 15, 2009

In Flex 3, I've created a ComboBox within an MXML component similar to the following:

<mx:ComboBox id="comboBox" dataProvider="{_choices}" />
<mx:Script> <![CDATA[
import mx.collections.ArrayCollection;
// etc...
public function get choices():ArrayCollection { return _choices; }
[Code] .....

In the parent MXML application, I'm modifying the contents of the choices property:
myComponentId.choices.removeAll();
myComponentId.choices.addItem({data: "NY", label: "New York"});
myComponentId.choices.addItem({data: "CA", label: "California"});
// etc...

The binding is working in that the ComboBox is automatically picking up the new contents added at runtime, however it is not adjusting its width. The initial width of the ComboBox is wide enough only to show the initial item "All" declared in the component. However, I want and would have expected the ComboBox to re-size automatically during binding to be able to show "California", but it isn't. How can I get the ComboBox to update its width after I have added new wider labels to its dataProvider?

Flex :: Binding ComboBox To XML Children?

Sep 9, 2010

I have created a really simple example for what I am trying to achieve, which you can see below.

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" horizontalAlign="center" verticalAlign="middle" initialize="init()">

[Code]....

So it is important for me to bind to the children().

Is this possible and if not, does anyone know how I will get round this issue?

Flex :: Setting A Custom ItemRenderer In A ComboBox On Specific List Items After Combobox Creation?

Nov 8, 2010

I'm trying to set a specific list item in a mx combobox to have a custom item renderer, the problem is that I cannot do this via mxml, it needs to be done via actionscript at a later stage, eg: combobox gets created, combobox gets populated, user does other tasks, combobox needs to set one or more items in the combobox to have icons (via item renderer)..

I can do this via the onChange event, but it only applies the icon when the combobox is opened and there is a slight delay so you can see the icon being added.

Flex :: Data Binding Re-bind When Data Model Not Change, Possible?

Nov 4, 2011

If user change the value of the TextInput, then click refresh button to retrieve the data model from backend again, the GUI value will not change back. Re-binding not happen, Since the value of data model not changed, no propertyChanged event fired.In this case, I must Programmatically set the model value to the GUI after data refreshing done.I know bi-directional binding can solve this problem(when user change value on GUI, set the new value to data model immediately). But sometimes I cannot use bi-directional binding, for example, the data model is a int, but user input a non-int value, I cannot set the value to data model. So the value in data model do not change, when refresh data, rebinding still not happen.

This will make the data binding useless. How to resolve this?I put pseudo-code here for now, I will put real code later:1. retrieve a data model from server, via blazeds or something else.2. bind the model to a TextInput on GUI.3. user change the TextInput text.4. User click a refresh button, triger retrieve the model value again.5. Now since the model value do not change, no PropertyChanged event fired.6. GUI value still is the user's input, not the value from the model. can clear the model value before set the velue back, make re-binding happen.(but sometimes you do not know how to clean the model value, take int for example, you may do not know the original value and happen set the same value). Or I can manually set the model value to GUI. But both are not good looking.

Flex :: Conditional Data Binding?

Oct 8, 2009

first one shows playheadtime of videodisplay and another is also used for same purpose. the difference is that when we are in add mode(decided from a flag variable) both should show current playheadtime using binding. but when we are in edit mode(again decided from flag) the latter label should remain static, to be more specific, the value retrived from database.how can I do that using actionscript. I tried ChangeWathcer but I found it a bit tricky. Is there any other simpler way or am I missing something. following is my code.

Flex :: Data Binding Not Working

May 3, 2010

I'm having some troubles with binding data. I have an application that contains a viewstack of components. Let's say I have comp1, comp2 and comp3 inside the viewstack. Each component, has its own data class --> comp1Data.as, comp2Data.as and comp3Data.as. All values in each component are binded to the corresponding data in it's data object.

A click in a control in comp1 leads to comp3, the same goes for comp2. Clicking a control in comp2 leads to comp3. When going from comp1 to comp3, comp3Data.as is initialized and and comp3 displays the binded values. When going from comp2 to comp3, comp3Data.as is also initialized but the binded values are not displayed...

Flex :: Data Binding With A Value Inside A Component ?

Mar 30, 2010

I'm using Flex with Cairngorm framework.I have a custom component which I create like this:

<components:FriendSearchPaginator id="searchResultsPaginator"
paginationElement="{_model.findFriendsPaginationElement}"
visible="{_model.friendsSearchResultsPaginatorVisible}" />

Where the findFriendsPaginationElement is inside the model locator:

public var
[Bindable]
findFriendsPaginationElement:PaginationElement = new PaginationElement();

Inside the custom component I have button that uses a property of findFriendsPaginationElement object:

<s:Button id="previousButton"
label=" prev "
click="paginateSearchResults(false)"
enabled="{_model.findFriendsPaginationElement.more_previous}"/>

But I get a warning from Flex that the binding wouldn't work that way and it doesn't. It works the first time I load up the component but every time I change findFriendsPaginationElement it doesn't reflect on the component. Do you know how I can go about doing this? (making changing a value in the binding variable changes the status of an element inside a component?)

Flex :: Two Way Data Binding In AS Causes Stack Overflow

Jul 21, 2010

I'm binding two AutoCompleteModified objects to one another; meaning you type in one and it selects the correct object in the other. It works fine when I define it in MXML: However, a user can add a new row to a Grid and then I set up the binding and objects via actionscript and it gives an 'undefined' error:
ChangeWatcher line 427/wrapHandler.

var innerHBox:HBox = new HBox();
var dtc_acm:AutoCompleteModified = new AutoCompleteModified();
dtc_acm.dataProvider = data2;
dtc_acm.labelField = 'id';
var cp_acm:AutoCompleteModified = new AutoCompleteModified();
[Code] .....

If I only keep it 1-way binding then it works fine. But both throw this error. Is there something about not only doing it 2-way in actionscript, but adding components that aren't on the stage yet?

Flex :: Update An Image Dynamically Using Data Binding?

Feb 20, 2010

I have a main.mxml application that lays out my application, it contains a "browse and upload" button. And contains an image to view the users uploaded image like so:

<mx:Application
<mx:Script>
<![CDATA[

[Code].....

In my myModel class I have a img_scld_bm that the browseAndUpload() function draws into after scaling it.

My intent is that my mx:Image will display the image. As shown here I'm assigning the image source="mymodel.img_scld_bm", this ends up just showing a broken image icon.

I also tried data binding, where in my myModel class I have [Bindable] var img_scld_bm. And then tried setting my mx:Image source="{myModel.img_scld_bm}" .. that didn't seem to do anything either. All this compiles fine, no warnings. I think in this case, I'm not setting a trigger or propertyChange event to update the binding?

how to correctly bind an mx:Image source to some bitmap?

Actionscript 3 :: Flex Data Binding Through A Refenced Property?

Jun 8, 2011

class A: with a property "data:ArrayCollection". It's my data source (data provider) and has bitmaps.

class B: has an instance of A (called "Ainst") and calls the following method: C.init( Ainst.data). To pass the data provider to Object C.

class C: has a reference of the data provider "data" (because of "init" method). It shows the arrayCollection into Images as: Image.source = data.getItemAt(0).

But C never updates its images, that is, data binding doesn't work with this scheme. I've put [Bindable] meta-tag in all properties and even classes.

Flex :: Setting SelectedColor Of ColorPikcer When Binding Data

Jul 5, 2011

How do you set the selectedColor of a colorpicker when you bind data from a database? I have a bindable variable, objProject, with a field called color and it has a color code such as #ff00ff in it. I want to set the selectedColor. I tried to cast the color as a uint, but no joy.

objProject = cmbProject.selectedItem;
c = uint(objProject.color);
<mx:ColorPicker id="graphColor" x="17" y="219" width="128" height="40"
selectedColor="{c}" editable="true" />
I did try selectedColor="{objProject.color}" and that didn't work either.

Data Binding - Flex Additional Label In ButtonBarButton?

Dec 5, 2011

I'm trying to extend ButtonBarButton to include an additional label that shows the number of updates for the respective box in a viewstack (which is the tabbar's dataProvider).

I can get the additional label (named indicatorLabel) to read an initial value from data, but I can't get it to update automatically like the actual "label" attribute. My understanding was that you could bind to the data object, but that doesn't appear to be the case.

Flex :: Passing Parameter From Main To Component With Data Binding

Flex :: Data Binding - Update Multiple Bindable Properties In Specific Order?

Apr 20, 2011

I have a situation where I need to update a DropDownList's dataProvider and selectedItem in a specific order. See the following code ...

<s:DropDownList id="dropDownList"
dataProvider="{someDataProvider}"
selectedItem="{someSelectedItem}" />

In my case, some user interaction produces new values for the bindable variables "someDataProvider", and "someSelectedItem". However, when flex renders the DropDownList, the control's selected value is empty.

The reason for this is that the DropDownList's "selectedItem" property gets bound before the "dataProvider" property. The "dataProvider" needs to be bound first for "selectedItem" to be valid, this is because the new "selectedItem" points into the new "dataProvider".

what is the best practice for updating bindable properties in a specific order? I've come up with a few ways (e.g. using a valueCommit handler), but I wanted to see what the community had to say.
