Hi
Can we add empty list in Combobox as shown below. After adding, i am using that combo box in Editor grid panel as one of the cell editor.But if I select any data other than " " (empty), a red mark is appearing in the editor grid panel cell. but if I select " " directly instead of any data, red mark is not appearing. Can I add empty like this or not.

],
fields: ['type', 'name']
});
var operatorEditor1 = new Ext.form.ComboBox({
store: operatorStore1,
mode: 'local',
triggerAction: 'all',
valueField: 'type',
displayField: 'name',
editable: true
});
Why not make the value something else? "_" or whatever. You could leave the display field as is.
hi,
Add a listener to the store and add the empty record like this.
var emptyRecord = new Ext.data.Record({type:' ', name:''});
listeners: {load: function(ds, records, o) { ds.addSorted(emptyRecord);
ds.commitChanges();} }
I think there are some syntax errors. Check them. But I hope this would help you.
