LinkButton in Datalist to delete...verify first?[RESOLVED]

[brendalisalowe]

I have a datalist and I have a LinkButton to delete. This is my code behind that:

Sub DataList_DeleteCommand(ByVal sender As Object, ByVal e As DataListCommandEventArgs)
        Dim conn As SqlConnection = New SqlConnection(ConfigurationSettings.AppSettings().Item("strConn"))
 
        Dim acctno As String = DataList1.DataKeys(e.Item.ItemIndex)
 
        Dim sql As String = "DELETE FROM CustomerRecords " & _
                            "WHERE ConsumerAccountNumber = '" & acctno & "'"
 
        Dim cmd As New SqlCommand(sql, conn)
        Try
            conn.Open()
            cmd.ExecuteNonQuery()
        Catch ex As Exception
            Response.Write(ex.Message)
        Finally
            If Not conn Is Nothing Then
                conn.Dispose()
            End If
        End Try
        DataList1.EditItemIndex = -1
        DataBinder()
    End Sub

I was just wondering if there is a way to have a MessageBox pop saying "Do you want to do this: Yes or No"?

I'm assuming JavaScript or something maybe? let me know. Thanks!
