Here is my code:
<mx:ComboBox prompt="" editable="true" dataProvider="{tableSelector.list}"/>
When this code executes, flex just sets the selectedIndex to 0 and displays the first item in the dataProvider instead of leaving the text and prompt as the empty string "". How do I get around this? I need the text property to be "" unless the user selects another item in the combobox.
I am using a s:TextInput in Flex 4.5. It shows it's prompt text if the underlying text value is null or empty String. Does anybody know if I can make either don't show the prompt on empty String or even show a different prompt?

View 1 RepliesI am kind of puzzled and not sure how to tackle this issue: Got two comboxes with dataproviders. Also, I created a separate index.as in /as folder. I have these two functions:

I get an error saying
Access of undefined property utilityType.
The funny thing is I don't get this error for "propertyCode". Moreover, If I copy pasyte showUtilityType() function and put inside my .mxml page, I don't get this error either. Btw. I have :

In my .mxml page. What should I do? How can I get rid of this error? Why does Flex see propertyCode combobox but not utilityType combobox? I would rather keep index.as as it is.
I have a prompt string to be displayed in my combobox - this needs to be displayed in italics. When user makes any selection from the list - i need to change the style of the displayed content.
My css file:
.promptStyle
{
fontStyle: italic;[code].....
I am able to see the style change happening because the color changes; but the change specific to textInputStyleName does not get applied.
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);

well, I have a combobox which I have bind his selectedItem property to a value object object, like this
<fx:Binding source="styles_cb.selectedItem.toString()" destination="_uniform.style"/>
<fx:Declarations>
<fx:XML id="config_xml" xmlns="" source="config.xml" />
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<mx:ComboBox x="66.15" y="63.85" editable="false" id="styles_cb" dataProvider="{config_xml.styles.style}" />
the value object is a custom class with some setters and getters, and I want to set a property based of the value of the selectedItem of the combo, so inside the value object I have something like this
[Bindable]
public function set style(value:String):void
{
_style = value;
trace(value);
}
my problem is that each time I change the combobox selection which in fact change the style property of the value object it does it 3 times, if I trace the value of the setter it actually do the trace 3 times, why?? how can I avoid this? I'm doing something wrong? or there is a better way to do it,

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.

View 3 RepliesI made a quick search in Google and I couldnt find what I need, basically, I want to set a padding in my combobox component, so the entire combobox (not the items inside) is a little separated from the previous component.
The combobox is contained inside a VBox container, and above there is a label. If I use the padding property, what it does is to decrease the Y position of the text inside, but the component doesn't move at all.
It's too complicate to explain but I'll give you an example
