Flex :: Programmatically Setting Chosen Item In ComboBox
Jan 26, 2011
I need to programmatically set the selected item in a combobox. I've got a combobox like this:
<mx:ComboBox id="MyComboBox" change="puzzleHandler(event);"prompt="Make a Selection">
<mx:ArrayCollection id="myDP">
<mx:Object id="first" label="Label 1" series="2" pageTitle="Title 1"/>
<mx:Object id="second" label="Label 2" series="7" pageTitle="Title 2"/>
<mx:Object id="third" label="Label 3" series="9" pageTitle="Title 3"/>
</mx:ArrayCollection></mx:ComboBox>
I've got a function that regards deep linking. [URL]. They'll be taken to the appropriate part of the site (without having selected Label 2 in the comboBox). How do I set the comboBox programatically, so that it corresponds with what the user it looking at? In my function's switch statement, I want to set the comboBox to the label that corresponds with the view. If "view=2" then the comboBox should show "Label 2" as selected.
case "view=1":
MyComboBox.selectedItem.label="Label 1";
parseUrl();
case "view=2":
[Code] .....
I tried this: MyComboBox.selectedItem.label="Label 1" But it's not working.

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.

I have a Spark List container whose dataProvider is bound to a result set coming back from a RemoteObject call. Pretty standard stuff.
<s:List id="list" dataProvider="{model.stuff}" width="100%" height="100%"
selectedIndex="@{selectedSlider.value}"
itemRenderer="{stuffRenderer}">
</s:List>
The selectedIndex is associated with an HSlider, but that is not the problem. My issue is that I would like to automatically select a certain "preferred" element from the list (only initially...to guide the user).
I tried to do that in a creationComplete event but my data hadn't shown up yet...setting selectedIndex didn't work..

I am using a combobox for the us states, link. The label is set to the full name of the state, while the value attribute holds the abbreviation. What I want to do is to get the selected item's value. So I tried combo.selectedItem.value and combo.selectedItem.@value, but neither of them worked.

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.

I've been playing with s:ComboBox and generally like them a lot. One detail is driving me nuts though - most likely due to my lack of knowledge in the subject - is that if I try to add a new item to my dataprovider in a changeHandler (registered to the change event) the text for the ComboBox textInput disappears - although the item addition works perfectly. Interestingly enough the same operation works fine if it gets called by clicking on a button, i.e. post the change event has been processed, and the text does not disappear.[code]if you take out the change handler you will see that adding a new item and then clicking on the button keeps the new element in the textInput while adding the item to the data provider, which does not happen if you just enter a new item and press enter.

issue is that when a user clicks a datagrid cell that has a combobox editor and then immediately clicks away from the cell, the text value in that cell disappears. I have an itemEditEnd handler on the datagrid and it shows the value of the property I use as the editorDataField just fine. But the labelFunction (which gets called after the itemEditEnd handler) on that grid column sees it as zero. Why aren't the labelFunction and item editor playing together nicely? Here is the DataGridColumn:

I've just recently started out using Flash Builder and have a question surrounding states. In fact I'm not entirely sure it is related to states but read on and I hope it will become clearer. I currently have a custom component that contains 3 comboboxes. This resides in a TabNavigator component. The TabNavigator consits of 5 pages (Tabs). The custom container holding the comboboxes should display the same selected data across all Tabs. ie. If I am in Tab1 and select an item from one of the comboboxes then click on Tab2 I need to mirror the combobox's selection in Tab2.

Isn't there a better way to accomplish this?[code]...
All I want to do is make sure that when I update the item that the comboBox is pointing to internally, that it's selectedIndex also update so that the label within the ComboBox reflects the new value.

Is there a way to reverse the order of the items in a comboBox? I'd like to use index numbers to refer to items in the arrayCollection below. I want the newest content to appear first in the comboBox. But, if I add something above the first item then all of the index numbers will be off by one. If I could add a new item to the end of the arrayCollection, but have it appear first in the comboBox drop down that would solve a lot of problems.

I am using the combocheck example from the following site: [URL]
It's a very useful component and works very well.
Now, I need to set the text property of this combo box upon application startup with certain values (which are defined dynamically according to some criteria). The problem is that although I have no problem setting the text property of the combo box at other times of the application run, setting the property at startup seems to have no effect unfortunately.
For example, I want to set the text property of the combobox to "Bob" (which is one of the items in the dataprovider for the combobox) and the "set text" method is called on the combo box. Performing a step-through shows that the "set text" method is receiving the correct value item but not setting the _text property.
I have tried not doing anything until "ApplicationComplete" but no joy there either.
Here is the code (a combination of the code from the URL above and some other changes to it). However, as I've stated above, the codes does work. The problem is that it doesn't work at the application startup. Whenever an event is fired and setComboText is called as a result, the text of the combo box is set correctly.
private function onComboChecked(event:ComboCheckEvent):void {
var obj:Object=event.obj;
var index:int=selectedItems.getItemIndex(obj);

Anyone know how to change a single instance of an item renderer for a Flex tree item at runtime? To reiterate, I'm not trying to change the entire tree's item renderer like this:tree.itemRenderer = new ClassFactory(ItemRenderer2);I'm trying to change the item renderer of a single tree item like this (the following code does not work):tree.selectedItem.itemRenderer = new ClassFactory(ItemRenderer2);To put it more simply, does anyone know how to reference an instance of an item renderer and set it to a new item renderer class? I've tried using the Tree's itemToItemRenderer() method with no success.

I have a ComboBox with a label function like this one:
private function fieldLabelFunction(item:Object):String {
return resourceManager.getString('dashboard',"SS." + item);
}
When I change locales, the labels display correctly in the ComboBox's dropdown list, or if I change a selection. However, the currently selected item's label doesn't refresh at first. Is there a way to force the labelFunction to get called again?

I've been playing around with renderers the last few days for a mobile application. I'm creating a gridlike renderer that has columns that is light weight for a mobile app. It is a bit of a poor man's datagrid. The layout is fine. The question I have is controlling the height of each row in the list.
When measure() is called, I set the measuredHeight to:
measuredHeight = getElementPreferredHeight(ld) + verticalPadding;
Where vertical padding is:
var verticalPadding:Number = getStyle("paddingTop") + getStyle("paddingBottom");
When I debug on the desktop, the measuredHeight is set to 12 and on the device (Motorola Atrix), it is set to 12. But when layoutContents is called, the unscaledHeight is a number much larger than my measuredHeight value (44 on the device, 66 when running on the desktop), resulting in more vertical whitespace surrounding each item than I care to have. How do I control that row height? I happen to be using a Datagroup for this particular example but in some playing around I did with just a simple list, I had the same issue. Somewhere the system is overriding my measuredHeight with some other value.

I have a comboBox component with a CHANGE event listener on it:
dd_chapter.addEventListener(Event.CHANGE, changeFunction);
function changeFunction(event:Event):void {
trace("changed!");
}
I want to trigger that event programmatically when the comboBox first gets loaded with data. In AS 2, the syntax would be something like "dd_chapter.onChange();". How do I do it in AS 3?
