You can custom the 'loadFilter' function to construct a new combined field, and then set the 'textField' property to this field name. Please look at this code.

Code:

<select class="easyui-combogrid" style="width:100%" data-options="
		panelWidth: 500,
		idField: 'itemid',
		textField: 'myfield',
		url: 'datagrid_data1.json',
		method: 'get',
		columns: [[
			{field:'itemid',title:'Item ID',width:80},
			{field:'productname',title:'Product',width:120},
			{field:'listprice',title:'List Price',width:80,align:'right'},
			{field:'unitcost',title:'Unit Cost',width:80,align:'right'},
			{field:'attr1',title:'Attribute',width:200},
			{field:'status',title:'Status',width:60,align:'center'}
		]],
		fitColumns: true,
		label: 'Select Item:',
		labelPosition: 'top',
		loadFilter: function(data){
			if ($.isArray(data)){
				data = {total:data.length,rows:data};
			}
			$.map(data.rows, function(row){
				row.myfield = row.itemid+':'+row.productname;
			});
			return data;
		}

</select>
