A lookup editor allows you to edit a value (BaseEdit.EditValue) only indirectly by selecting a row from a dropdown. The dropdown displays rows from a specific data source specified by the RepositoryItemLookUpEditBase.DataSource property. When a row is selected, the row’s value from the field specified by the RepositoryItemLookUpEditBase.ValueMember property is assigned to the edit value, the row’s value from the RepositoryItemLookUpEditBase.DisplayMember field is displayed within the edit box.
