Actionscript :: Flex CheckBox ItemRenderer Not Tied To Object?
Jun 12, 2011
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.

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 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:
<mx:List id="peopleIncludedList"
dataProvider="{someProvider}"
labelFunction="peopleLabelFunction">

If I have a component that has some states defined, is there a way to make changes in design mode but not have it tied to a particular state? For example, if I have state1 and state2, any changes in design mode will be based on state1 or state2 (i.e. width.state1). I understand this is the direction Flex is going in but I'm transitioning from a Flex 3 app and right now I just want to make the change to width and not width.state1.

I have a Tree, which has an itemRenderer. On the itemRenderer, driven by the XML conditions, objects are created dynamically and added as a children to nodes. These new objects shall trigger an event handler ( some click events mostly ). How do I pass the event handler to the tree and later to the dynamically created new objects inside itemRendere?
Something like:
<mx:Tree x="534" y="49" newObjectsOnClick="newObjectsOnClickHandler">

i have a problem using the itemRenderer functionality. When using an ArrayCollection the visible Data in the DataGrid using the itemRenderer will be rendered just fine. But if i start scrolling the entries are repeating in the cells using the renderer. The cells are not filled with date according to the id. What mistake i'm doing here.
I read a lot of the explainations like:

Anyone know how to change a single instance of an item renderer for a Flex tree item at runtime? To reiterate, I'm not trying to change the entire tree's item renderer like this:tree.itemRenderer = new ClassFactory(ItemRenderer2);I'm trying to change the item renderer of a single tree item like this (the following code does not work):tree.selectedItem.itemRenderer = new ClassFactory(ItemRenderer2);To put it more simply, does anyone know how to reference an instance of an item renderer and set it to a new item renderer class? I've tried using the Tree's itemToItemRenderer() method with no success.

I have implemented drag and drop between 2 AdvancedDataGrid, but the default behaviour from Flex displays the row data during the drag using the grid item renderer showing all 5 columns.
Instead, I would like to display an icon / image or my own custom item renderer during the drag and drop.

I want to create a list of progress bars and update the list accordingly.I have group data in an Array as
<mx:Array id="arr">
<mx:Object label="Group One" min="0" max="200" currentValue="60" />
<mx:Object label="Group Two" min="0" max="300" currentValue="50" />[code]....
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
<mx:List width="100%" dataProvider="{arr}"
itemRenderer="mx.controls.ProgressBar"/>
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").

How can we navigate within an itemRenderer? For example, in Views we use the View.navigator (ViewNavigator) to push and pop views, there is no such feature in ItemRenderer.

<s:Button label="Questionnaire" click="navigator.pushView(view.QuestionnaireCategory1View)"/>

I have a List which has TextInput as itemRenderers for all its items. Upon application launch the items are rendered in the TextInputs correctly. The data is being populated from an Array of Objects.
What I want is, after the data has been populated in the ItemRenderers, I want to have an additional item renderer (TextInput of course)...so that if the user wants to enter another item, he can put it in the additional textInput.
And I also want to add the additional itemRenderer each time the user has added a new item and taps ENTER on the newly added item.
Below is my itemRenderer, there is the clearTxt_enterHandler handler..but I wonder how to add another itemRenderer upon "Enter".

<mx:DataGridColumn headerText="Visible" dataField="visibleInd" width="48"

But in this case my code does align the checkbox in the middle, but does not save data in my dataprovider.

I've had a good rummage around the interweb and can't seem to find any examples of a tri-state checkbox. It doesn't look to be supported in the SDK and I can't find any examples online. I would imagine this is a common problem, before I embark on writing my own does anyone know of a good flex tri-state checkbox component somewhere I can use :)

I have an AC with several questions and assoicated answers. These must be shown in a DG, and the idea is that the rows and colums of the DG are bound to the AC. For example, if the answer to question1 is Yes, the Yes-button must be true, and both the others must be false (as in normal radiobuttongroup behaviour). But when I change a button by clicking it, the actions datafield of the AC should change accordingly. Am I clear enough here?
It is ment for dynamic questionnaires.
