I'm trying to reach the dataField of a DataGridColumn in the itemRenderer. Below is the dataGrid:
<mx:Script>
<![CDATA[
[Bindable] public var weeksOfMoth:ArrayCollection = new ArrayCollection([
{monday:30, tuesday:31, wednesday:1, thursday:2, friday:3, saturday:4, sunday:5},
{monday:6, tuesday:7, wednesday:8, thursday:9, friday:10, saturday:11, sunday:12},
{monday:13, tuesday:14, wednesday:15, thursday:16, friday:17, saturday:18, sunday:19},
{monday:20, tuesday:21, wednesday:22, thursday:23, friday:24, saturday:25, sunday:26},
{monday:27, tuesday:28, wednesday:29, thursday:30, friday:1, saturday:2, sunday:3}
]);
]]>
</mx:Script>
<mx:DataGrid dataProvider="{weeksOfMoth}" >
<mx:columns>
<mx:DataGridColumn itemRenderer="view.DateRenderer" dataField="monday" />
<mx:DataGridColumn itemRenderer="view.DateRenderer" dataField="tuesday" />
<mx:DataGridColumn itemRenderer="view.DateRenderer" dataField="wednesday" />
<mx:DataGridColumn itemRenderer="view.DateRenderer" dataField="thursday" />
<mx:DataGridColumn itemRenderer="view.DateRenderer" dataField="friday" />
<mx:DataGridColumn itemRenderer="view.DateRenderer" dataField="saturday" />
<mx:DataGridColumn itemRenderer="view.DateRenderer" dataField="sunday" />
</mx:columns>
</mx:DataGrid>
And this is my ItemRenderer:
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" >
<mx:Box >
<!-- How do I get the dataField here?? -->
<mx:Label text="{data[dataField]}" />
</mx:Box>
</mx:Canvas>
In the set data function of the itemRenderer, I receive an entire week (which is ok), but the itemRenderer doesn't know which day to use because the dataField is unknown. Does anyone know how to reach this dataField in the itemRenderer?
The comment by www.Flextras.com helped me to find the solution. I can indeed use listData.dataField
, but first the IDropInListItemRenderer
class needs to be implemented.
The final ItemRenderer
:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" implements="mx.controls.listClasses.IDropInListItemRenderer" >
<mx:Script>
<![CDATA[
import mx.controls.dataGridClasses.DataGridListData;
import mx.controls.listClasses.BaseListData;
// Internal variable for the property value.
private var _listData:DataGridListData;
// Make the listData property bindable.
[Bindable("dataChange")]
// Define the getter method.
public function get listData():BaseListData
{
return _listData;
}
// Define the setter method,
public function set listData(value:BaseListData):void
{
_listData = DataGridListData(value);
}
]]>
</mx:Script>
<mx:Box width="80%" height="80%" verticalCenter="0" horizontalCenter="0" backgroundColor="#FFFFFF">
<mx:Label text="{data[_listData.dataField]}" />
</mx:Box>
</mx:Canvas>
