How do you force Combobox dropdowns to stay open even when other Alert boxes appear. Looking at what to subclass from mx.Combobox, there doesn't seem to be much that i can do to short of implementing an entire combobox from scratch.Thx
For that you need to create a custom ComboBox which if created in following Link. and might be this link will going to be useful to you.

I use the same DataTemplate to populate some of the views inside my CarouselView: a XAML file with a ContentView. I assign a custom class list to ItemsSource of the carouselview AND use bindings inside the template layout fields to fill them with the properties of my custom class. Everything is working fine. Here comes the wierd part: Let's say there's a button in the template and when you click it on the screen, a Label with "Well Done" text is added to the current Stacklayout of the shown carouselview. This is done by the codebehind of my template XAML. This is ok, too, but I expect this "Well Done" to disappear after I swipe back and forth enough. Because it's not part of the template. It does not disappear, instead I see it on other carousels once in every 4 swipes and it is replaced, I mean it appears on different carousels if I swipe back and forth. To make it disappear completely I have to swipe away from the views that share the same DataTemplate. I cannot understand the mechanics behind this behaviour. I can create another field inside the template to put the "Well Done" text there and show it when the time comes, I know. But I want to understand the mechanics. Thank you.
Asking the right question about a problem is the key to any solution..
After the realization that I've mentioned at the Update comment, I've searched for DataTemplate Caching and found this issue post on Xamarin.Forms Github: https://github.com/xamarin/Xamarin.Forms/issues/9200
There you can find an explanation to how CollectionView was designed and understand the mechanics behind the behaviour. No bug. It's by design.
when user clicks on Add button, then a pop up button will be opened with certain form elements (like textinput, date field, text area).. When i used 'TAB' inside this form,it is not working. I found in couple of Questions / forums that we need to create an instance of FocusManager and then bring/activate focus for the pop up. But still i didn't see the tab working inside the form. In order to tab order working inside a pop up, what steps we need to follow.
I tried using focusmanager and property like tabfocusenabled, tabenabled and also added taborder inside each form element. But no luck.
Iam using Flash Builder 4.5 and using spark components for development.
Is there any workaround for this problem?
Thanks in Advance,

Thanks for all your responses.
Finally the issue has been solved by one of my colleague. Problem is , the form has been loaded inside Horizontal accordion (flexlib HACCORDION). So inorder to draw focus inside the accordion to child elements, we need to add 'hasFocusableChildren="true"' for the HAccordion (horizontal accordion component). Adding this property solves the tab order problem.
I have also pasted the code below:
I have a tab and want another tab with click of button.
Another tab has VBox (Contains charts,grid etc).
It gives an error while adding code addChild(), removeChild() on button click.
The error is of null object reference.
Please suggest me.
Thanks
You're probably trying to access children of a tab that has not been initialized yet. The simplest solution is to change the creationPolicy property of your TabNavigator to "all".
You can see an explanation of creationPolicy in the Adobe documentation.
If this is not the solution, you're probably going to have to post more specific code.
I am denying a user the ability to drop into my tree during certain conditions, it's all going well, but I want to tell the user why I'm denying the drop. I would prefer to do it with a toolTip, but it doesn't seem to work. Can I not have a toolTip during a drag operation? How can I force one?
Flex seems to treat toolTips as a property of the UI component, with the component deciding when and if to show it. I would like it to force it to be like doing one in javaScript where it was always just like saying "Show it now" "stop showing it now"
Does anyone know about doing this during drag?
Thanks

What you could try is to show the tooltip yourself with the mx.managers.ToolTipManager. Create for example a VBox that implements mx.controls.ToolTip and displays the message you want to show to the user.
You can see a working example at FlexExamples.
Another idea is to show a programmatic mouse cursor when the drop is denied. I've just read an article about that on Inside Ria.
This is my first question here.
I hope I can contribute with answers too..
My need is to build an Extjs TriggerField implementation which open on trigger click a Panel with a custom loaded page inside...
example: When I click the trigger button I what to open a panel specifying an url as /Views/Test/Blabla.aspx and then storing the selection in the trigger field value.
I hope someone could help me
Thanks in advance
There is an example which pops up a Panel in your examples directory under examples/form/forum-search.html
It's based on a ComboBox (But it configures it to hide the trigger button)
BTW, probably a better idea to ask for help at http://extjs.com/forum/
