ComboBox editors in EditorGridPanels return the valueField value to the cell, not the displayField. That's the biggest problem with ComboBox's in EditorGridPanels that there is so far, and the only answer to it is to use a custom renderer with that column that can get the displayField value from the data store that is attached to the ComboBox. It's a bit of a long-way-around trip to get what should be easy, but this is one of those things that doesn't seem to have had to much thought put into it by the developers so far unfortunately.

Its a bit of coding, but is easy to understand

//Combo Renderer
comboRenderer= function(value) {
var record = yourComboName.store.getById(value);
return record ? record.get('text') : '';

//Combo Definition
var yourComboName= new Ext.form.ComboBox({
typeAhead: true,
triggerAction: 'all',
listClass: 'x-combo-list-small',
displayField: 'text',
valueField: 'value',
id: 'value'

//Combo Column
var comboColumn = {
header: 'yourHeader',
dataIndex: 'yourDataIndex',
width: 150,
renderer: comboRenderer,
editor: yourComboName
