数据修改的问题

[foundAnswer]

我通过StringGrid修改ADODataSet中的数据，下面是代码：


procedure TfrmGroupList.grdGroupListSetEditText(Sender: TObject; ACol,
ARow: Integer; const Value: String);
var
i: Integer;
begin
i := 0;
ADSGroupList.First;
while i < (ARow - 1) do
begin
ADSGroupList.Next;
Inc(i);
end;
ADSGroupList.Edit;
ADSGroupList.Fields[ACol].Value := grdGroupList.Cells[ACol,ARow];
end;

总是报Field "XXX" can not be modified.
谁能告诉我为什么？谢谢。

ADSGroupList.open了没有

对在ADSGroupList.Edit;前加上ADSGroupList.open

我已经open了，还是抱着个错呀！

procedure TfrmGroupList.grdGroupListSetEditText(Sender: TObject; ACol,
ARow: Integer; const Value: String);
var
i: Integer;
begin
i := 0;

ADSGroupList.Edit; //位置改变

ADSGroupList.First;
while i < (ARow - 1) do
begin
ADSGroupList.Next;
Inc(i);
end;
//ADSGroupList.Edit;
ADSGroupList.Fields[ACol].Value := grdGroupList.Cells[ACol,ARow];
end;

还是不行呀。如果ADSGroupList.Edit提前，在执行ADSGroupList.First后，ADSGroupList.State的值就变成了dsBrowser.

我要急死了！Field "XXX" can not be modified！！！

我想应该有人碰过这种问题吧！
