A few weeks ago Dan Vega blogged about creating a comboxbox (drop down) cell editor for the editable <cfgrid> before he realized that cfgrid supports in cell drop downs. I commented that I'd like to see something like a date picker cell editor and after using Dan's orginal code as inspiration and some hints from this post by Scott Bennett I finally got the thing working. Yes, I do realize that sometimes it'd just be easier to roll your own Ajax widget from scratch, but sometimes hacking it is more fun.
I'll leave it to Dan and Scott's original posts to explain the details, but here is what you'll end up with:
And here's the code:
<cfsetting showdebugoutput="false">
<cfajaximport tags="cfinput-datefield" />
<html>
<head>
<title>Edit Artist Grid</title>
<link href="/CFIDE/scripts/ajax/ext/resources/css/ytheme-aero.css" rel="stylesheet" type="text/css">
<style>
.x-menu-list{
margin: 0px; padding: 0px;
}
</style>
<script type="text/javascript" src="/CFIDE/scripts/ajax/ext/ext-all.js"></script>
<script type="text/javascript">
function init(){
//grid object
grid = ColdFusion.Grid.getGridObject("ArtistGrid");
//column model
cm = grid.getColumnModel();
//we need to know the column id
stIndex = cm.findColumnIndex("LASTMODIFIED");
var df = new Ext.grid.GridEditor(
new Ext.form.DateField(
{
format: 'm/d/Y',
minValue: '04/01/08',
}
)
);
cm.setEditor(stIndex, df);
cm.setRenderer(stIndex, Ext.util.Format.dateRenderer('m/d/Y'));
grid.reconfigure(grid.getDataSource(),cm);
}
</script>
</head>

postalcode, email, '04/01/2008' as lastModified
