Flex :: Unable To Bind The SelectedIndex Of A DropDownList To The SelectedIndex Member Of A Bindable Class
Feb 8, 2012I am unable to bind the selectedIndex public property of a spark DropDownList to it's original source in the view's presentation model.

Debugging the application I find that selectedIndex in the presentation model always remains at the default value assigned regardless of which item I selected from the DropDownList. For the sample code above this is -1.How can I bind the selectedIndex in the presentation model such that it is updated appropriately when the selected item DropDownList changes?

Flex :: Why Does TileList SelectedIndex Not Get Updated
Aug 14, 2009In the code below, the presentedAlbumIndex is used to control the selectedIndex of the TileList. Item "five" is initially selected. Whenever the button is pressed the first item in the array is deleted, and the presentedAlbumIndex is decremented.
In theory, the selected index should stay with "five" every time the button is clicked (until "five" is itself deleted). It works this way for the first button press. However, on the 2nd button press the highlighting changes to "six" for some reason. Also, the TileList selectedIndex is always one behind.
I tried looking into ListBase and monitoring selectedIndex. It looks like the selectedIndex is updated initially to the correct index, but then it reverts back at some point to the correct index+1. I do not know why it's setting back.
It seems it's due to the fact that I am doing a data provider delete and index change in the same operation.
Is there some function in TileList I could override to keep selectedIndex up to date?

Flex :: Set SelectedItem In DropDownList?
Sep 10, 2011I am making some simple project and I have problem with selectedItem. I have sth like this
<s:State name="Form" enterState="makesService.send()"/>
so when I enter this state I take makes from database and populate them to dropdownlist.
but I have also button and on click event I'm changing state to this Form and I want to select specific make from the dropdownlist but I can't. I'm not sure whether I'm doing sth wrong or the problem is that I'm selecting item just before the dropdownlist became populated.

Flex :: How To Change Open DropDownList Height
Feb 18, 2010Using FB4, I want to change the height of an open spark DropDownList. By default, it shows up to 6 items before scrolling. My dropdownlist contains 7 items, so I want to change the height of the open dropdown list to fit all 7 items without scrolling. As a workaround, I've changed the font size of the items so that they are smaller and all 7 fit, but the smaller font doesn't look good. Is there a way to change this height?

Flex :: DropDownList Doesn't Work In New Window
Oct 29, 2010In this code I'm creating a new window when I click the button. In the new window are TextInput and DropDownList components. When the new window opens, clicking the DropDownList does nothing - you have to click it a second time round to get it to open. However, click into the TextInput field first and then try opening the DropDownList works no problem.
Below is the code, or download the FXP file here.

Flex :: Spark DropDownList As ItemEditor Within AdvancedDataGrid?
Mar 11, 2011I'm trying to use the Spark DropDownList as itemEditor in an AdvancedDataGrid. Howerver, I've stumbled onto two issues:Clicking on a item in the DropDownList changes the selected row in the ADG. You can see this behavior by compiling the code from below and executing the following steps.The value changes from "A" to "C" and Row 3 is the selected row in the ADG. It looks like the mouse click in the DropDownList is also handled by the ADG itself which changes the selected row accordingly. I couldn't figure out a way to prevent this. The expected behavior would be that row 1 is still selected after the DropDownList has been closed.Clicking on the scrollbar of the DropDownList closes the DropDownList. (I just found the solution to this problem in the relatated questions while writing this: Scrollbars in dropdownlist inside DataGrid itemEditor not working)

Flex :: DropDownList Doesn't Always Open On Click?
May 12, 2011I have an AIR application with 2-3 DropDownLists and a bunch of other controls. The DropDownLists are bound to dataproviders (ArrayCollections) in a central Model singleton. On launch, they all work fine.
However, when I click a button to add new objects to an object in another ArrayCollection in the same Model, the DropDownLists get weird. They still register clicks, and all other controls still work as before, but the dropdowns won't open. Clicking/waiting enough usually opens the dropdown, but if I don't make another selection it still won't open after closing. Making a different selection makes that DropDownList work again, but the others might still refuse to open.
If I open the dropdowns using Ctrl + Down arrow, they work all the time, so it's only the click that doesn't trigger the open correctly. I can work around the problem by calling openDropDown() on the dropdown when clicked, but that doesn't feel right.
I'm using the 4.1 SDK, and the dropdowns are s:DropDownLists. I tried using mx:ComboBoxes instead, but got the same behavior. Edit: Weirdly enough, using s:ComboBoxes they work as they should, but I really don't want to use them since they seemingly can't be made non-editable.
