我有一个表单，可以从我的 MSSQL 服务器中的表中选择一堆行，现在，此表单用于更新数据，它可以正确执行，但是在我使用表单更新数据后，它会重定向回一个页面该表中所有行的数据网格，并允许我选择另一行进行更新，如果我再次选择刚刚更新的行，我会收到“用户 'slehan_ticketadmin' 登录失败”。
现在我知道用户名/密码是正确的，因为我在一分钟前使用了表格来更新数据。我无法查看 SQL 错误日志，因为我的主机限制了我，但这是我更新表单的代码。
namespace YakStudios_Support.ys_admin
{
public partial class UpdateTicket : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
int ticketID = Convert.ToInt32(Request.QueryString["ticketID"]); // Grabs the ?ticketid number from the URL
Ticket ticketBeingUpdated = TicketDatabase.selectTicketFromDatabase(sqlErrorLabel, ticketID); // Creates a new Ticket object to be used by the form to populate the text boxes
/* Form Field Population */
// Email
emailTxt.Text = ticketBeingUpdated.getEmail();
// Date Submitted
dateSubText.Text = ticketBeingUpdated.getDateSubmitted().ToString();
// Ticket Class
classDropDown.SelectedValue = ticketBeingUpdated.getTicketClass();
// Ticket Status
statusDrop.SelectedValue = ticketBeingUpdated.getStatus();
// Subject
subjectTxt.Text = ticketBeingUpdated.getSubject();
// Text
textTxt.Text = ticketBeingUpdated.getTicketContent();
}
}
protected void editBtn_Click(object sender, EventArgs e)
{
emailTxt.Enabled = true;
dateSubText.Enabled = true;
classDropDown.Enabled = true;
statusDrop.Enabled = true;
subjectTxt.Enabled = true;
textTxt.Enabled = true;
}
protected void submitBtn_Click(object sender, EventArgs e)
{
int ticketID = Convert.ToInt32(Request.QueryString["ticketID"]); // Grabs the ?ticketid number from the URL
DateTime convertedDate = Convert.ToDateTime(dateSubText.Text);
Ticket ticketUpdated = new Ticket(emailTxt.Text, convertedDate, subjectTxt.Text, textTxt.Text, statusDrop.SelectedValue, classDropDown.SelectedValue);
TicketDatabase.updateTicketInDatabase(ticketUpdated, sqlErrorLabel, ticketID);
Response.Redirect("ticketqueue.aspx");
}
}
}
您看到的 Ticket 类只是一个保存从 SQL Server 更新/选择/删除的票证数据的类，它只是我以结构化方式修改/保存数据的一种简单方法。我想引起您的注意：
Ticket ticketBeingUpdated = TicketDatabase.selectTicketFromDatabase(sqlErrorLabel, ticketID);
我有另一个名为 TicketDatabase 的类，它有一堆从数据库中插入/选择/更新/删除票的方法。这是 selectTicketFromDatabase() 方法存根。
public static Ticket selectTicketFromDatabase(Label sqlErrorLabel, int ticketID)
{
SqlCommand sqlCmd = new SqlCommand("SELECT * from yak_tickets");
using (SqlConnection selSqlConn = new SqlConnection(sqlConn.ConnectionString))
//using (sqlConn)
{
sqlCmd.Connection = selSqlConn;
selSqlConn.Open(); // Open the SQL connection
//sqlCmd.Connection = sqlConn;
//sqlConn.Open(); // Open the SQL Connection
SqlDataReader reader = sqlCmd.ExecuteReader();
Ticket ticketReturning = null; // Initializes the ticketReturning but it's not allocated
// Call during reading
while (reader.Read())
{
/* Objects to hold values from reader */
string emailString = reader["email"].ToString();
DateTime dateSubbed = Convert.ToDateTime(reader["dateSubmitted"].ToString());
string subjectString = reader["subject"].ToString();
string textString = reader["ticketText"].ToString();
string statusString = reader["statusid"].ToString();
string classString = reader["ticketClass"].ToString();
ticketReturning = new Ticket(emailString, dateSubbed, subjectString, textString, statusString, classString);
}
selSqlConn.Close();
return ticketReturning;
}
}
我将在 localhost 服务器上对此进行测试，看看是服务器还是我的代码导致了错误，但我仍然愿意接受对此特定问题的建议/支持。
提前致谢！
