thanks you very much! it works fine with my case.

Hello Cuong,

EditorOptions setting overrides the ComboEditorOptions setting.That's the reason you see this behavior. What you need to do is to keep the EditorOptions configuration, but also adding the combo configuration settings as JSON string like this:

.EditorOptions("dataSource:" + Html.Raw(ViewBag.PricingSource) + ", valueKey: 'ID', textKey: 'Description', mode: 'dropdown', enableCleatButton: true, validatorOptions: {onblur: true, keepFocus: 'once', validated: grdFairPriceSourceValidate}")

Hope this helps,
