Flex :: Labelfunction Interferes With Combobox Item Editor

Jun 27, 2011

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:

Flex :: Force A ComboBox's LabelFunction To Be Called For The Selected Item When Locale Changes?

Sep 3, 2009

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?

Flex :: ComboBox LabelFunction Not Refreshing With Updating Of An ArrayCollection?

Aug 11, 2010

My first issue is that when my ArrayCollection only has one item, for some reason I cannot select that first item. The change function set on the mxml never gets called when I try to select that one item. If I set a prompt, it works. I know that the item is not already selected because when debugging, the selected item shows null. I do not want to use a prompt. I want the first item in the ArrayCollection to be selected automatically. So if there is only one item, I want the selected item to be that. FYI - I am using a labelFunction to format the data in the Array Collection. why I cannot select the first item or set the first item in the ArrayCollection to be the selected item?

My bigger issue is that when my Array Collection gets updated, my label function must not be refreshing because when I first open the dropdown, it has specfic data. When the Array Collection gets updated and I open the dropdown again, I see the old data in the dropdown, yet it doesn't exist anymore.

So let's say I have a ComboBox that has a datasource of an array collection of one state code and it's state name. Their is a labelFunction that puts a dash in between the state code and the state name. Their is no prompt, so the ComboBox would look like GA - Georgia and when you open the dropdown, that would be all that is there. I want that item to be selected automatically. why the old data shows up when opening the dropdown after the array collection was updated with new data?

<mx:ComboBox labelFunction="getFormattedNpaNxxCollectionList()"
dataProvider="arrayColl" change="doSomething()"/>
public function getFormattedNpaNxxCollectionList(item:Object):String
{
return StringUtil.substitute("{0} - {1}", item.stateCode, item.stateName);
}

Flex :: Keep Item Editor While The Focus Is On The Layer

Jul 19, 2011

I am using a combo-box as a Datagrid ItemEditor (Not just Renderer, my Renderer is a Label, double clicking on a cell makes the combo-box visible, as is the case with all item editors) Now, selecting one of the entries in the combo-box is no problem. But my problem is only when i select the "Fruit", which in turn pops open another layer called "Select Fruit" dialog

Questions: How do i keep item editor, while the focus is on the layer; right now as soon as i click on the fruit, my handler popsup the "Select Fruit" dialog and the focus is on the layer. Once the focus goes out of the editor, the ItemEditor goes away and ItemRenderer label comes back. I want to keep the ItemEditor alive! where do I hook up interms of events like begin/end ItemEdit etc?

Flex :: Intercept Value Passed To Item Editor?

Dec 28, 2011

I'm trying to intercept the value that is taken from a DataGrid's GridColumn's itemRenderer and applied to the itemEditor, and vice-versa. I need to be able to format this value. However, my project is complex, so I may be focusing on the wrong idea in what I'm trying to accomplish.

I have a Spark DataGrid component (with ID dg) that I am dynamically populating from XML. I create an ArrayCollection from some nodes, and a regular Array from sub-nodes that is added as a property of the ArrayCollection. That ArrayCollection is then used as the dataProvider for the DataGrid.

Here is an example segment of a typical XML node and it's sub-nodes:

<item name="physOrderTable" text="" type="notes">
<cols>
<col id="0" text="Day/Time" />

[Code].....

This is the only method I've been able to use to achieve the desired result. This all works fine, if all I want to do is merely display information. But I need to be able to edit the values in each cell, and apply this back to the dataProvider, as I need to rebuild XML with the updated values later.

I have tried everything I can possibly think of to be able to do this. I built my own itemRenderer, then my own itemEditor, then scrapped them because it felt like I was re-inventing the wheel. But was I? I tried reading through the code for the DataGrid, GridColumn, and related classes, but I couldn't find any reference to the itemEditor beyond it being an IFactory. I have no idea where or how it tells that IFactory to be a text input or whatever it is.

Here is my issue:

When I turn on the DataGrid's editing, and double-click a cell, it takes the entire array of the col dataField for that column's cell, converts that array to a string, and displays the entire string in the edit text box. If I cancel the editing, or save the editing, it sets the string to the .col property. Then the labelFunction tries reading that string as an array, and it crashes. I was able to get the typeof the col dataField and converting it to an array if it's a string, but I shouldn't have to.

I need to have it display just the value of the cell for that particular row and column when the instance of the itemEditor is created. When that value is changed, I need it to apply back to that column's index in the .col array of the dataProvider. So, similarly to how it displays information in the labelFunction, I need to edit the information and send it back.

I've seen lots of custom itemEditors and itemRenderers for GridColumns, but these are hard-coded in the MXML. My grid is almost entirely dynamically created, so that's unfortunately not an option for me, as I won't even know how many columns or rows there will be when the DataGrid is created. I tried using rendererIsEditor, but that only seems to be on the MXML instantiation of the GridColumn, as there's only rendererIsEditable in the ActionScript, and it doesn't seem to work (or I don't know how to use it as intended).

Flex :: Datagrid As Item Editor Gets 'itemEditEnd' Prematurely?

Apr 18, 2011

My application has a tree with a custom item renderer, which depending on the type of data at a leaf uses different components as editors. In one case I am trying to use a datagrid so that the user can choose a row that meets his needs (several columns need to be displayed), ie. similar in concept to a ComboBox.To do this I have a function assigned to be the handler for 'itemEditBegin' (for the tree) in which I'm dynamically creating the datagrid, and then using the popup manager to display it as a (modal) popup. So far so good.

However, if you click anywhere (eg. scroll down button in the datagrid) the popup disappears because the itemEditEnd event is fired - why ?In another scenario, I have a DateField setup as the editor, and the user can click on the icon to bring up a DateChooser, scroll through the months, etc. I looked at the code behind this, and it is using a popup, seemingly in exactly the same way as my code !Here is the 'itemEditBegin' code:

dataGrid = new DataGrid();
dataGrid.dataProvider = mddTable.dataCollection;
dataGrid.editable = false;

Flex - ComboBox Is There An Event For Item Hover?

Apr 7, 2010

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.

Flex :: Spark ComboBox Displaying Text For New Item?

Sep 16, 2010

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.

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: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.

Flex :: Maintain Combobox Selected Item Across TabNavigator Tabs?

Mar 30, 2010

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.

Flex :: Reverse Order Of ArrayCollection So That The Last Item Appears First In A ComboBox

Jan 26, 2011

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.
