Flex :: List - Checkbox Itemrenderer Enabled Property?
Nov 10, 2010
I have a list that uses a checkbox itemrenderer. The dataprovider is a collection of people. When I load the data from a file, each list item shows the person's name (last, first -- labelFunction), and the checkbox's selected property shows the person's included property. I.e.,Smith, Doug - [x]Williams, Bob - [ ]orris, Anne - [x]However, each person also has an active property. I want to disable the checkbox for people who are inactive (meaning, "you can't include inactive people").to do the same thing in a datagrid. However, none of them work and all the checkboxes are enabled regardless of the person's active status. Here is my basic code:
i used iteamreander in datagrid . if i select checkbox in grid automatically select another checkbox why? plz explain My xml data is more then 50 records.
I have an itemRenderer as CheckBox in a Flex DataGrid. Now, I want to make sure that only one checkbox is selected at a time. If user select's a checkbox, and then tries to select another checkbox, previous selection should be cancelled out.
I have button like random click ,if i click this button then will select 15 checkbox within datagrid itemrenderer checkbox But i can't access the checkbox ? please refer me ? How can access the checkbox ?
I need to create a Flex component similar to ComboCheck (by Arcadio Carballares).What I need is a ComboBox with CheckBox and TextInput instead of Checkbox's label.If CheckBox is selected the TextInput is enabled and editable, other way it's disabled.
I am using a 'Tilelist' and 'HBOX' as itemrenderer. In the HBOX I have checkbox.Passing arraycollection as dataprovider to TileList(my arraycollection length is 20). On selecting checkbox of item1 in the Tilelist and scroll the list I could see subsequent item as of item1 is selected. In blogs I found there is some issue of flex cache while using checkbox.
I have an Actionscript class we'll call Person to make the example easy. I want to have a DataGrid populated with Person objects that has columns displaying things like Name, Birthday, etc. All that is nice and simple, but I would also like to add a checkbox column to select certain people in the DataGrid. An example use case would be as follows:
Display all people. User checks a box next to each person indicating they want some action taken on those selections. Some action is taken on the user selections when the user clicks a button.
It seems like the common solution to this is to make a Selected property on each Person object, but that isn't really a good option for me. The Person object is used throughout the application, and it seems very unclean to have a Selected property which really isn't a concern of the Person class.
I like the type safety of having hard classes like Person, but I don't know how to solve this seemingly simple problem so I can loop through the objects and determine if the person is selected or not.
In datagrid i shows number of checkbox for example 20 checkboz ,in 20 checkbox if i select any 15 checkboxs then remining checkboxs will be disable (enabled="false" But 15 selected checkbox accessable ? How can i do that . i tried
I have a Flex list and a custom ItemRenderer. I'd like to be able to have some items in the list use a different ItemRenderer (say, depending on the class of the item). Is this possible?
It seems like it should be a simple concept. I need a vertical list. This list has an image with a checkbox and pathname of that image underneath it. The user should be able to check the checkboxes of the images they want to appear in their "shopping cart". The images, checkbox label, and list are populated by an XmlList. How can I do this in Flex 3.5 and Actionscript and have a button that when clicked, display a list of the checked items??
I'm creating a list of scores for a game. now most of the list i need to have the same ItemRenderer. but in one specific row of the list where the user who's playing is listed, it should show different information and with different background color. how can i achieve this ?
I already tried to resolve the issue with states, i created 2 states, one state called 'mine' and the 2nd state called 'others'.
the problems that i got is that when users click on one of the list rows that state changes to i donno clicked or something and that's why i assumed that states are not the right action for me.
I have a List with textInput as itemrenderer. Initially the list is loaded with data from a data provider. However since the items are rendered in textInputs, I have the ability to change the value of a particular item.
But when trying to access the value of the changed item using the function below, I still get the old value in my trace:
private function addItem(event:Event):void { trace(myDataProvider.getItemAt(myList.selectedIndex).label); }
what I need to do for the new value to be available. My itemrenderer is shown below:
i am using an itemRenderer in mx:list, it has many text fields and combos, i use this item renderer to edit items in array collection, each item in the arrayCollection is of type Action which comes from BlazeDS remoting as a valueObject.my problem is when i add new item of type Action to the list dataProvider (ArrayCollection) by this code
myList.dataProvider.addItem(new Action());
the new item tooks the same data from its previous item.
Is there a direct way to get the item index of the data inside an itemRenderer? I need to display the item number against each item. I am currently doing a workaround and won't allow reuse of my itemRenderer component.
var index:int = model.dataColl.getItemIndex(data) + 1; itemNo = index.toString();
This is what i am using now, it works, but the concepts of component reuse and data abstraction are compromised.
I'm using a custom itemrenderer to display a list of photos and need to know how to control the width. At the moment it does this: Which, as I'm sure you'll agree, is eye-bleedingly ugly. The list is created like this:
In Flex I can create an ItemRenderer to represent each item in the Lists DataProvider but how do I access the instance of the ItemRenderer via the DataProviders Object? Something like myList.getItemRenderer(dp.getItemAt(10));
The values in the array object indicate name of group,minimum,maximum and current value for the group (to be used in progressbar).I used the list with "mx.controls.ProgressBar" as itemRenderer as
Now what I need is whenever currentValue field of Array "arr" changes i want to update the progressbar "progress" value to currentValue (where min and maximum value of progressbar are stored in Array "arr").
I've wrote a custom itemrenderer for a List component (Flex 3.5) which is a VBox with a Label and a TextArea wrapped inside. All works fine so far but I want the TextArea in the first itemrenderer to receive focus so that it instantly becomes editable when tabbing onto the List. Is that possible and if how would I achieve this?
I've already added an event listener that selects the item at index 0 but the textArea in it should also be focussed at that moment _list.addEventListener(FocusEvent.FOCUS_IN, onListFocusIn);
private function onListFocusIn(e:FocusEvent):void { _list.selectedIndex = 0; }
I am using a spark list control with an itemrenderer. Whenever I set an itemrenderer's currentState, the moment I mouse out of the itemrenderer, it gets reset to its default state. How can I make an itemrenderer keep its currentState unless I explicitly tell it to change?
The thing is, if I scroll the list, and click on an item, it does not trace 'arthur' ! Why is this so ? I must trace that all the time that someone clicks in the list!
EDIT: If I remove change="model.selectSet( productSetList )" in the list, it works!! but I cannot remove that, some suggestions ? How can I switch that to another function?
Objective:I would like to pass Skins to an itemRenderer (which is a Button) of a List, and be able to skin every button in that List.This is what I have:
I want to set the BorderColor of certain Item Renderers (textInput) of a List. By default all have a common border color, but I want for example when clicking in an item to have a red border. I tried this on a click event in my itemRenderer,
I have a list inside a VDividedBox. When the box is resized so the vertical scrollbar shows on the list, it covers some of the itemrenderers. How do I get the list to resize horizontally so that the scrollbar does not cover the renderers?
I have a List component that has drop-in CheckBox itemEditor that also serves as the itemRenderer. It displays each item as a simple CheckBox with a label.
However, the itemEditEnd Event does not get triggered until I click on something outside of the List. I want it triggered once the CheckBox is checked or unchecked.
I was thinking of manually dispatching the ListEvent.ITEM_EDIT_END in a CLICK Event handler, but then the itemEditEnd Event would get dispatched twice. There's gotta be a better way to do this.
I have a main application that contains a list, using a custom itemRenderer to display data.
I would like to be able to call a function, inside the itemRenderer, from the main application.
When running the app, we have a list with three persons, and a button. I want to call the function myItemRendererFunction() inside the itemRenderer, of the selected item in the list, all this, from the main app.
