请专家诊断:DBGRID多行选择的处理

[ymxxm]

如何解决Delphi ： “multiple records found,but only was expected”错

在处理DBgrid多行选择时用到如下代码：
With DBGrid1.DataSource.DataSet do
Begin
for i:=0 to DBGrid1.SelectedRows.Count-1 do
begin
GotoBookmark(pointer(DBGrid1.SelectedRows.Items[i]));
Edit;
....
但执行至Edit指令时Delphi报出“multiple records found,but only was expected”
请高手指点迷津！

DBGrid的属性有没有设对?
其他未发现问题,您再试试?

Query1的SQl为'Select * from comployee where rownum<=10;
Query1.updateobject:Updatesql1
缓冲。
使用如下代码触发错误：
With DBGrid1.DataSource.DataSet do
Begin
for i:=0 to DBGrid1.SelectedRows.Count-1 do
begin
GotoBookmark(pointer(DBGrid1.SelectedRows.Items[i]));
Edit;
