Hello Richard,

You can either set AppendDataBoundItems="true" for the dropdown list and add default empty item in the dropdown control or set a predefined value for the dropdown control onInitInsertCommand. Check out the section 'DropDownList has a SelectedValue which is invalid because it does not exist in the list of items' under the following help document for more information on this:
