$(function(){
		$('#tt').datagrid({
			title:'Editable DataGrid',
			iconCls:'icon-edit',
			660,
			height:250,
			singleSelect:true,
			idField:'itemid',
			url:'datagrid_data.json',
			columns:[[
				{field:'itemid',title:'Item ID',60},
				{field:'productid',title:'Product',100,
					formatter:function(value){
						for(var i=0; i<products.length; i++){
							if (products[i].productid == value) return products[i].name;
						}
						return value;
					},
					editor:{
						type:'combobox',
						options:{
							valueField:'productid',
							textField:'name',
							data:products,
							required:true
						}
					}
				},
				{field:'listprice',title:'List Price',80,align:'right',editor:{type:'numberbox',options:{precision:1}}},
