C# 更新表单而不更新详细信息

我创建了一个简单表单来显示用户详细信息，其中包含以下字段：

First Name
Surname
Team Name
Team Stadium
Email
Receive Reminder
Receive Summary

我检索登录用户的详细信息，并允许编辑字段以进行更新。但是，当“更新”按钮的“单击”事件被触发时，字段将返回其原始值

这是我的C代码#

对于ASP

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolderMain" runat="server">

我已经尝试在SQL Management Studio中使用存储过程，它会按预期进行更新，因此由于某些原因，在单击“更新”时字段不会读取更新的值

任何建议都很好，谢谢

您应该只在第一次从数据库加载数据，因此必须检查它是否不是回发

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        LoadDataFromDatabase();
    }
}

private void LoadDataFromDatabase()
{
    SqlConnection conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["RaiseFantasyLeagueConnectionString"].ConnectionString);
    SqlCommand cmd = new SqlCommand("[dbo].[GetUsersProfile]", conn);
    cmd.CommandType = CommandType.StoredProcedure;

    string userId = Membership.GetUser().ProviderUserKey.ToString();
    SqlParameter userIDParam = new SqlParameter("@userId", userId);

    cmd.Parameters.Add(userIDParam);

    conn.Open();
    SqlDataReader dReader = cmd.ExecuteReader(CommandBehavior.CloseConnection);
    while (dReader.Read())
    {
        FirstName.Text = (dReader["ManagerFirstName"].ToString());
        Surname.Text = (dReader["ManagerSurname"].ToString());
        TeamName.Text = (dReader["TeamName"].ToString());
        StadiumName.Text = (dReader["TeamStadium"].ToString());
        Email.Text = (dReader["Email"].ToString());
        Reminder.Checked = (bool)dReader["RecieveReminder"];
        Prediction.Checked = (bool)dReader["RecieveSummary"];
    }
    dReader.Close();
    conn.Close();
}

在页面加载事件中使用IsPostBack

if(!IsPostBack)
{
        SqlConnection conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["RaiseFantasyLeagueConnectionString"].ConnectionString);
        SqlCommand cmd = new SqlCommand("[dbo].[GetUsersProfile]", conn);
        cmd.CommandType = CommandType.StoredProcedure;

        string userId = Membership.GetUser().ProviderUserKey.ToString();
        SqlParameter userIDParam = new SqlParameter("@userId", userId);

        cmd.Parameters.Add(userIDParam);

        conn.Open();
        SqlDataReader dReader = cmd.ExecuteReader(CommandBehavior.CloseConnection);
        while (dReader.Read())
        {
            FirstName.Text = (dReader["ManagerFirstName"].ToString());
            Surname.Text = (dReader["ManagerSurname"].ToString());
            TeamName.Text = (dReader["TeamName"].ToString());
            StadiumName.Text = (dReader["TeamStadium"].ToString());
            Email.Text = (dReader["Email"].ToString());
            Reminder.Checked = (bool)dReader["RecieveReminder"];
            Prediction.Checked = (bool)dReader["RecieveSummary"];
        }
        dReader.Close();
        conn.Close();
}

if(!IsPostBack)
{
        SqlConnection conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["RaiseFantasyLeagueConnectionString"].ConnectionString);
        SqlCommand cmd = new SqlCommand("[dbo].[GetUsersProfile]", conn);
        cmd.CommandType = CommandType.StoredProcedure;

        string userId = Membership.GetUser().ProviderUserKey.ToString();
        SqlParameter userIDParam = new SqlParameter("@userId", userId);

        cmd.Parameters.Add(userIDParam);

        conn.Open();
        SqlDataReader dReader = cmd.ExecuteReader(CommandBehavior.CloseConnection);
        while (dReader.Read())
        {
            FirstName.Text = (dReader["ManagerFirstName"].ToString());
            Surname.Text = (dReader["ManagerSurname"].ToString());
            TeamName.Text = (dReader["TeamName"].ToString());
            StadiumName.Text = (dReader["TeamStadium"].ToString());
            Email.Text = (dReader["Email"].ToString());
            Reminder.Checked = (bool)dReader["RecieveReminder"];
            Prediction.Checked = (bool)dReader["RecieveSummary"];
        }
        dReader.Close();
        conn.Close();
}
