ActionScript 3.0 :: Combobox Change Event Isn't Fired

Feb 12, 2009

I've got this weird problem with Flash in a embed browser in an ASP.NET Windows Application. I've got this Flash Movie that runs in the Windows application and has got a couple of comboboxes. I've added an eventlistener to such a box, but his change event isn't triggerd on some computers. When I click on the combobox it opens up, but when I click on an item in the combobox it closes before he could trigger the change event.

The weird part is that this occurs on some computers, on others it works as it should. And when I load the swf directly in the browser the comboboxes work all the time. So it has something to do with the Windows Application and Flash. All the tested computers have the Flash plugin version 9 and higher (needed for my movie) installed.

Data Integration :: Populating Datagrid From Combobox

Jul 5, 2006

I am trying to populate a datagrid based on a value selected from a combobox. The data comes from a xml file, which looks something like this,[code]The user can list data in the datagrid based on either "media" and "region." For example, the user should be able to choose "Europe" from the combobox and list "only" media having "Europe" in the region tags. In this case, if the user chooses "Europe" from the Combobox only one listing (rammstein) will be seen in the Datagrid.However, it doesn't work. I get a blank datagrid. Loading data into the datagrid is not the problem, because if I just use a straight For loop with no conditions I fill the datagrid no problem. The problem comes up when I try to control what data get listed in the datagrid based on selected value in the combobox.[code]

Flex :: Not Receiving An Event Fired From An .AS Class

Jul 16, 2010

I have 2 files, 1 to dispatch the event and 1 to receive it (of course in addition to the event class itself).

I've done this before with both dispatching and receiving files being mxml, but this time the dispatching file is an actionscript class, and it's not working this time. Is it different for actionscript classes?

Here's a dumbed down version

The dispatching class dispatches the event as soon as it's created.

public class ASClass extends UIComponent{
public function ASClass(){
dispatchEvent(new MyEvents(MyEvents.FIRE_EVENT));
}
}

in my main mxml app, I instantiate the ASClass which automatically dispatch the event as soon as it's created and the main mxml app should receive back.

protected function appCComplete(event:FlexEvent):void{
addEventListener(MyEvents.FIRE_EVENT, gotEvent);
var asClass:ASClass = new ASClass();

Flex :: What Event Is Fired When All SkinSparts Are Available In A SkinnableComponent

Feb 12, 2011

I'm (slowly) learning Flex 4 and working on skinning a custom component that extends SkinnableComponent. The component is all in ActionScript and essentially looks like this:

[Code]...

The issue I'm having is on NULL REFERENCES in the Constructor for the various SkinParts, because they're not created yet. I'm trying to find out when is the best time to access them to assign their .text values. I know I can override partAdded() and add the .text value as each part is added, but I'd rather just listen for some magic event that is dispatched when they're all available.I'm not sure whether or not it matters, but the accountName, accountNumber variables are assigned by using a repeater with a dataProvider on the host component. I'm not sure if that too has something to do with when the data is available to the AccountSummary component - which may also needed to be waited on. I was able to successfully use FlexEvent.CREATION_COMPLETE to assign all my .text values to the SkinParts, but is that the right event/best practice?

Flex :: Get The Value Of A ComboBox That Is In A DataGrid?

Oct 6, 2009

I have a data grid that has ComboBoxes in two of its columns.

What I need to do is get the values of those bombo boxes when a user highlights the row of the grid NOT when the user uses the comboBox. I understand how to pull the values out once the change handler is invoked on the comboBox, but I'm not seeing a way to get at the comboBoxes that belong to the currently highlighted gridRow.

I'm sure it's really straight forward, but I'm just not able to find any reference on how it's done.

Flex :: Get The Value Of A ComboBox Within A DataGrid?

May 12, 2010

I have a DataGrid with a ComboBox as an ItemRenderer for one of my columns. When the user selects a row, I want to get the ComboBox's selected value for the selected row.

EDIT: I should have mentioned that the dataField2_Array property in myData is actually an Array is the dataProvider for the ComboBox. Each object in myData could have completely different values in that Array so the ComboBox in each row of the DataGrid could have completely different options to pick from.Some sample code:

<mx:DataGrid id="myGrid"
dataProvider="{myData}">
<mx:columns>[code].....

Flex :: Filter A DataGrid With A ComboBox?

Oct 28, 2009

How can I filter a datagrid based on the value in the combo box? Can anyone show me some good examples on it?

In my application, I already filter a datagrid based on the text entered by the user. I check if the entered string matches the column entry of the datagrid and if a match is found,the filterFunction on the dataprovider is called.

This is that code:

<mx:FormItem direction="horizontal">
<mx:ComboBox id="searchCriteria1" dataProvider="{criteriaDP1}" change="searchFunction()"/>
<mx:TextInput id="search" change="searchFunction()"/>

[Code]....

searchCriteria is the comboBox,where I have the items, "ALL","HIGH"...I have two rows with value "high" and I get the Alert "yes" for two times only.. But in the data grid all the four rows are displayed.

Flex :: Using An ArrayCollection To Populate Both A Datagrid And A ComboBox

Aug 11, 2010

I use this arrayCollection to populate a Flex 3 Datagrid. I'd also like to use this arrayCollection to populate a comboBox with the Name node.

In the arrayCollection, I've got the Name listed twice. I've got two rows in the Datagrid.

If I set the ComboBox's labelfield to Name, then the Name will be listed twice in the ComboBox menu. Is there a way to use this arrayCollection and have each Name listed only once in the comboBox?

I can always make another loop and array collection for the Name, but I was wondering if there were a better way.

var i:uint;
for (i=0; i<myArray.length; i++){

Flex :: Combobox Selection Inside Datagrid?

Mar 1, 2011

I have a datagrid.In this datagrid I have a combobox item editor. This datagrid also has multiple columns where a user inputs numbers in each column. These numbers are then calculated by formula where the sum is posted in the "total" column. In this combobox there are two options for the user to choose from and each option has a different formula for calculating the inputted numbers. What I want is for when a user chooses "option 1" one formula is used to do the calculation, when "option 2" is chosen by the user then formula two is used to the calculation.Here's an example:

Combobox Option 1 (formula 1) is chosen by user = (Column2 - Column1) x column3 = "total" column
Combobox Option 2 (formula 2) is chosen by user = (Column1 - Column2) x column3 ="total" column

I realize you would use a conditional such as "if else" statement, but im just not sure how to do it. I've been trying to implement this for a while with no success.

Flex :: ComboBox In DataGrid Loses Values When Scroll Horizontally

Dec 14, 2009

I have a very strange problem in a Flex 3.4 Datagrid. One of the columns is a ComboBox - I have my own custom renderer for the ComboBox. I use it to select my data and then make a "save" to the db. Upon return the comboBox loses its value. Even stranger is that when I scroll the datagrid area to the left (by moving scrollbar right) - the values in the ComboBox change!! When I scroll the datagrid right (by moving the scrollbar left) - the values in the ComboBox don't change.

Flex :: Value In Datagrid Itemrenderers Set Data Method Doesn't Return The Correct Data?

Jan 10, 2012

I've got a Gridcolumn in a Datagrid (Spark). The Column's dataprovider is a Number value that gets updated via Binding.Now, without an item renderer the cell displays the correct values.If I set an item renderer, I can't access the values in this renderer.My renderer looks like this, so nothing really do here (for now) but to trace the value, but the value is always NaN.

<?xml version="1.0" encoding="utf-8"?>
<s:GridItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark" width="100%" height="100%" >[code].......

without the renderer, the column displays the correct values, so apparently the DefaultGridItemRenderer works fine.As requested, here is my Datagrid;

<s:DataGrid id="dataGrid" dataProvider="{_listItems}">
<s:columns>
<s:ArrayList>[code]..........

_listItems is an ArrayList with instances of a model class, which has (amongst others) a property called change of type Number.

Flex :: Data Passed From DataGridColumn.itemToLabel To DataGrid.itemRenderer.set(data)?

Dec 4, 2009

I have a DataGrid whose dataProvider is an Array of int Arrays (each with different lengths). Since each row has variable size (and I want to display all the data), I decided to extend DataGridColumn and overwrite the itemToLabel function to be able to display the data. The problem is that I also need to display the data differently depending on the int value.

I believe the only solution is to write an itemRenderer, but the only input the itemRenderer.set(data) function receives is the entire int Array. I believe I need either the exact string returned by itemToLabel or the column index of the cell the itemRenderer is for (to basically do the same parsing I implemented in itemToLabel).

Flex - ComboBox Is There An Event For Item Hover?

I'm using the <s:ComboBox> flex component which I suspect is very similar to the mx one <mx:ComboBox>

What I'm trying to do is listen to the event of the mouse moving between the items of the list. There's a change event, but it kicks in only when the item is clicked/selected from the list.

What event would I need to listen for when items are just hovered over. I tried finding over and hover but couldn't find something to that effect.

ActionScript 3.0 :: Event.AddedToStage Being Fired Twice?

Mar 19, 2011

I've just been working on a splash page/main menu for my game, and when tracing a value in the function fired when added to stage, I noticed it was tracing twice.After a process of elimination I found it was caused by some text inside a movieclip in the library.

This is literally my first time using MovieClips in AS3, as I generally just render everything manually, but I used one to knock up some quick text.When converting the text to vector graphics, the problem disappeared. Still the same MC being created and added, yet no problem. It was caused by the text.Doing away with MC's completely, embedding the required font and just using manual TextFields is my solution.Tested on 2 different FP10 builds by the way, same behaviour on both.
