I'm using WebDataGrid with DropDownProvider. and I bound DataTable to the DropDownProvider.

The property "DisplayMode" of EditorControl has DropDown, DropDownList, ReadOnly and ReadOnlyList.

I know how ReadOnly (or ReadOnlyList) works.

but I couldn't find the difference between DropDown and DropDownList.

using ReadOnly, it binds only 1 item. using ReadOnlyList, it binds all item

but DropDown binds all item of the DataTable.

please explain the difference.

Thanks.
