Re: [.NET] datagrid刪除資料的問題
※ 引述《yauhh (姚呵呵)》之銘言：
※ 引述《yukimir (小環)》之銘言：
: 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 標題 =" &
: 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 標題 = '" &
dg.DataKeys(e.Item.ItemIndex) & "'"
com = New OleDbCommand(sqlstr, con)
com.ExecuteNonQuery()
con.Close()
data()
End Sub
結果可以刪了 可是會同時刪我按的那筆和它的下一筆資料
如果想刪最下面的一筆就會發生問題這樣！
這樣的話要怎麼辦┬︿┬?
