You can add one key value pair to data source of comboBox. Set its value to null or int.MinValue when display member is string.Empty.

i know that. but when i clear it with backspace the selected index still remains.

yes if you are removing string the 'selected index' will be same, because there is not any index available for empty string
you add an empty string element in your combobox
