: Protected Sub dg_DeleteCommand(ByVal source As Object, ByVal e As
: System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dg.DeleteCommand
: Dim con As OleDbConnection
: Dim com As OleDbCommand
: Dim provider = "provider=microsoft.jet.oledb.4.0"
: Dim database = "data source=" & Server.MapPath("db2.mdb")
: con = New OleDbConnection(provider & ";" & database)
: con.Open()
: com.CommandText = "delete from guestbook where 标题 =" &
: dg.DataKeys(e.Item.ItemIndex)
: com.ExecuteNonQuery()
: con.Close()
: data()
: End Sub
我把上面那段改成
Protected Sub dg_DeleteCommand(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dg.DeleteCommand
Dim con As OleDbConnection
Dim com As OleDbCommand
Dim sqlstr As String
Dim provider = "provider=microsoft.jet.oledb.4.0"
Dim database = "data source=" & Server.MapPath("db2.mdb")
con = New OleDbConnection(provider & ";" & database)
con.Open()
sqlstr = "delete from guestbook where 标题 = '" &
dg.DataKeys(e.Item.ItemIndex) & "'"
com = New OleDbCommand(sqlstr, con)
com.ExecuteNonQuery()
con.Close()
data()
End Sub
结果可以删了 可是会同时删我按的那笔和它的下一笔资料
如果想删最下面的一笔就会发生问题这样！
这样的话要怎麽办┬︿┬?
