We are not clear about your requirement. We suspect that, you need to set the empty value for corresponding column whenever you want, through a dropdownlist.
If so, then we suggest you to have a null value in your data source for that corresponding column. So while rendering the dropdown control the null value is shown as empty in the dropdownlist, you can select the empty item from the dropdownlist.
