Hi guys,
I have a datagrid with a custom button renderer built in Actionscript.
I'm trying to figure out how to capture the click event of the component
when the button is clicked.
I'm generating the component from the cell depending on the type of
field:
column.itemRenderer = new ClassFactory(DpFileRenderer);
The actual component:
package joe.ui {
import mx.controls.Button;
import flash.events.MouseEvent;
import flash.events.Event;
public class DpFileRenderer extends Button
{
[Embed("/assets/icons/drive_disk.png")]
private var diskIcon:Class;
[Embed("/assets/icons/drive_disk_grey.png")]
private var diskIconDisabled:Class;
override protected function updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void
{
super.updateDisplayList(unscaledWidth, unscaledHeight);
this.label = this.listData.label;
if(this.listData.label != '0')
{
this.setStyle("icon", diskIcon);
} else {
this.setStyle("icon", diskIconDisabled);
this.enabled = false;
}
this.labelPlacement = "left";
this.setStyle("color", 0x000000);
}
}
}
I'm not exactly sure on where to put an event broadcast in there that
fires when the user clicks on the button.
Could anybody help?
Thanks.

OK, now I've gotten rid of the VBox, but still do not see how I can set
a different dataProvider to the comboBox, or dynamically set the
selectedIndex.
Again any help is greatly appreciated.

Your itemRenderer is not a ComboBox, it is a VBox containing a ComboBox.
The DataGrid sets the .data property on the VBox and you haven't written
the code to pass it on down to the ComboBox.
You can either write that code, or use ComboBox as the top-level tag so
you are really using a subclass of ComboBox as the renderer, which is
the recommended practice.

Subject: [flexcomponents] Struggling with itemRenderer in DataGrid
Help.
I posted this on FlexCoders with no response, so I thought I would try
here too.
I'm trying to use an itemRenderer to create a comboBox in a DataGrid
that is being created with AS.
I can create the comboBox, but I am struggling with being able to change
the dataProvider for the rendered comboBox, and setting the selected
index on the comboBox.
The relevant code I am using is below.
Any help is GREATLY APPRECIATED as I am rapidly approaching a deadline.

{
_datagrid = positionsGrid; // positionsGrid is an already created
DataGrid object

_col5 = new DataGridColumn;
_col1.headerText= "Position";
_col1.dataField = "Description";
_col1.editable = true;
_col1.width = 100;
