RepositoryItemLookUpEdit编辑列如何输入新值

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

/ solution 1 private void LookUpEdit1_ProcessNewValue(object sender, DevExpress.XtraEditors.Controls.ProcessNewValueEventArgs e) { DataRow Row; RepositoryItemLookUpEdit Edit; Edit = ((LookUpEdit)sender).Properties; if(e.DisplayValue == null || Edit.NullText.Equals(e.DisplayValue) || string.Empty.Equals(e.DisplayValue)) return; Row = LookupTable.NewRow(); Row["Name"] = e.DisplayValue; LookupTable.Rows.Add(Row); e.Handled = true; } // solution 2 private void LookUpEdit1_ProcessNewValue(object sender, DevExpress.XtraEditors.Controls.ProcessNewValueEventArgs e) { DataRow Row; RepositoryItemLookUpEdit Edit; Edit = ((LookUpEdit)sender).Properties; if(e.DisplayValue == null || Edit.NullText.Equals(e.DisplayValue) || string.Empty.Equals(e.DisplayValue)) return; using(Form2 f = new Form2()) { f.ItemID = "(Auto Number)"; f.ItemName = e.DisplayValue.ToString(); if(f.ShowDialog(this) == System.Windows.Forms.DialogResult.OK) { e.DisplayValue = f.ItemName; Row = LookupTable.NewRow(); Row["Name"] = f.ItemName; LookupTable.Rows.Add(Row); } } e.Handled = true; }
