原文：https://www.devexpress.com/Support/Center/Question/Details/A2911

he solution to your problem is very simple:

 1) Keep the View's OptionsData.Editing option active.

 2) Implement the View's OnEditing event handler as follows:

[Delphi]Open in popup window

procedure <Form>.<View>Editing(Sender: TcxCustomGridTableView;

AItem: TcxCustomGridTableItem; var AAllow: Boolean);

begin

AAllow := Sender.Controller.FocusedRecord.IsNewItemRecord;  // NewItemRow is focused

end;
