How To Access ComboBox's properties from its item renderer

[comgeek]

my Code is like this

<mx:ComboBox labelField="name">
<mx:itemRenderer>
<mx:Component>
<mx:TextInput text={data[labelField]} />
</mx:Component>
</mx:itemRenderer>
</mx:ComboBox

In itemrenderer I want to get the labelField property of the combobox
but how can I get it..

when I used this.parent in itemrenderer its showing some 'ListBast and
not the 'ComboBox'

Did you try giving an Id to combox and tried accessing it directly or by using outerDocument ?

Use like this

<mx:ComboBox labelField="name">
   <mx:itemRenderer>
       <mx:Component>

            <mx:TextInput text={data.name}    />

       </mx:Component>
 </mx:itemRenderer>
</mx:ComboBox

I can do that., but I want to do it I want to do this as a (reusable
custom component).. so I tried using 'parent.' but 'parent' from
itemrenderer is pointing to Listbox(dropdown of combobox), and I also
used 'parent.parent' but no use..

Is there any other way?

Hi,

You can try this.

/** CustomComboBox.mxml**/
<?xml version="1.0" encoding="utf-8"?>
<mx:ComboBox xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:itemRenderer>
<mx:Component>
<mx:TextInput text="{data.outerDocument.labelField}" />

</mx:Component>
</mx:itemRenderer>
</mx:ComboBox>

/** Sample.mxlml **/
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="vertical" xmlns:local="*">
<mx:Array id="arr">
<mx:Object label="Student A" score="85" />
<mx:Object label="Student B" score="48" />
<mx:Object label="Student C" score="71" />
</mx:Array>
<local:CustomComboBox dataProvider="{arr}" labelField="score" />
<local:CustomComboBox dataProvider="{arr}" labelField="label" />
</mx:Application>

RajPrabha

Hi,

Create a custom combo box and use outerDocument.labelField to get
combo box's labelField.
Check the following code. If you find any other better solution, plz
post it.

/**CustomComboBox.mxml**/

<?xml version="1.0" encoding="utf-8"?>
<mx:ComboBox xmlns:mx="http://www.adobe.com/2006/mxml">

<mx:itemRenderer>
<mx:Component>
<mx:TextInput text="{data[outerDocument.labelField]}" />

</mx:Component>
</mx:itemRenderer>
</mx:ComboBox>

/**Sample.mxml**/

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="vertical" xmlns:local="*">

<mx:ArrayCollection id="arrColl">
<mx:source>
<mx:Array>

<mx:Object label="Student A" score="85" />
<mx:Object label="Student B" score="48" />
<mx:Object label="Student C" score="71" />
</mx:Array>

</mx:source>
</mx:ArrayCollection>
<local:CustomComboBox dataProvider="{arrColl}" labelField="score" />
<local:CustomComboBox dataProvider="{arrColl}" labelField="label" />
</mx:Application>

With regards,
RajPrabha

Hi,

Really sorry for the previous post.

In that example, item renderer [TextInput] is not displaying.
Use the following code.

<?xml version="1.0" encoding="utf-8"?>
<mx:ComboBox xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:itemRenderer>
<mx:Component>

<mx:HBox>
<mx:TextInput width="100%" height="100%" text="{data
[outerDocument.labelField]}" />
</mx:HBox>

</mx:Component>
</mx:itemRenderer>
</mx:ComboBox>

Worry for the inconvenience

Raj
