1.在RunDesiger的Repository内置编辑器设置ProcessNewValue事件2. Private Sub RepositoryItemLookUpEdit1_ProcessNewValue(ByVal sender As System.Object, ByVal e As DevExpress.XtraEditors.Controls.ProcessNewValueEventArgs) Handles RepositoryItemLookUpEdit5.ProcessNewValue Dim Row As DataRow '添加新（空）行 Row = CType(RepositoryItemLookUpEdit1.Properties.DataSource, DataTable).NewRow() '给新行各列赋值 Row(DESCRIPTION) = e.DisplayValue.ToString().Trim() Row(PARTNO) = '将新行加入到该类编辑器绑定的集合
