經Datagrid去Delete Record!!!!!!!!!!!!!!(編號：2571)

本人用:
Adodc1 for retrieve data
Datagrid1 for show data
Adodc1.recordset.
用 Addnew, delete and update 作為data 存取
Case:
當有兩筆資料一樣時, 本想delete one record that point to the datagrid1 currently.
本人用 -＞ Adodc1.Recordset.Delete -＞DoEvents 但失敗!!

"Run-time error! Insufficient or incorrect key field information; too many rows affected by update."

Thank you!
