[flexcoders] Re: Data Binding Issue
Hi,
My Requirement is the developer can either pass a list of selected items
or not. If he does, then I need to select the check boxes after it's
creation. That's the reason I have the code:
selected={ selectedItems.contains(chkRepeater.currentItem) }
which will select the checkboxes if there were any in the
selectedItems
Hope this helps..
Thanks,
Madhu

[flexcoders] Re: Data Binding Issue
Hi Tom,
Here is the code for the custom component. It contains two arraylists.
dataItems and selectedItems. dataItems is the complete set of list for
which the check boxes should be generated. selectedItems is the list
which has the items (checkboxes) to be selected. The user will send a
list of completeList of items (dataItems) and a selected list of items
from the main MXML.
//Code for the Custom Component
?xml version=1.0 encoding=utf-8?
mx:Canvas xmlns:mx=http://www.adobe.com/2006/mxml
http://www.adobe.com/2006/mxml width=100% autoLayout=false
horizontalScrollPolicy=off verticalScrollPolicy=off
creationComplete=initComp()
mx:Script
![CDATA[
import mx.collections.ArrayCollection= new ArrayCollection();
[Bindable]
public var dataItems:ArrayCollection = new ArrayCollection();
[Bindable]
public var selectedItems:ArrayCollection;
]]
/mx:Script
mx:Tile id=chkTile
mx:Repeater id=chkRepeater dataProvider={dataItems}
mx:CheckBox id=chkCheckBox
selected=selectedItems.contains(chkRepeater.currentItem)
label={chkRepeater.currentItem.label} styleName=glass
uid={chkRepeater.currentItem.value} /
/mx:Repeater
/mx:Tile
/mx:Canvas
//Code for the Main MXML
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
layout=absolute creationComplete=initComp() xmlns:view=view.*
mx:Script
![CDATA[
import mx.collections.ArrayCollection;
[Bindable]
private var completeList:ArrayCollection = new ArrayCollection();
[Bindable]
private var selectedList:ArrayCollection;
private function initComp(){
//Assume that I will get a list of Items (checkBoxes in this case) to be
created
completeList = ..
}
]]
/mx:Script
view:MultipleOptionsCheckBoxView dataItems={completeList}
selectedItems={selectedList}/
/mx:Application
I am binding completeList to dataItems and selectedList to
selectedItems. My ultimate goal is, if the developer passes a list of
selectedList then the checkboxes should be selected (after creation)
based on the items the developer passed. If the developer doesn't pass
anything, then when ever a user selects a list of items, they should be
available to the developer in the local variable selectedList (as there
is a binding). I think you understoood my requirement. Everything works
fine for me except when the selectedList (local variable in the
Main.mxml) is not initialized. If I initialize this local variable, then
the binding works fine (both sides). If I have a list of selectedList,
then also the binding works. The only problem is when the selectedList
is null. If I initialize the variable in the custom component (when it
is null) the binding fails. I dont want to use mx:Binding tag (which
also works fine in all situations)...
Let me know if I miss anythingor confused you a lot..
Once again, thanks for your help
Madhu
