I would like my end users to have the ability to clear the combobox values and save the blank data. When you clean the value and tab away from the combobox the gird shows the previous value and a change event for that row is not fired.
If the value for the Kendo UI ComboBox widget is set to empty string the validation message should be shown and prevent model update. Could you please replicate the described problem with http://dojo.telerik.com/eBiFA example?
