更新表单不更新详细

我创建了一个简单的形式来显示用户的详细信息，有以下字段：更新表单不更新详细

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

我检索了详细的登录用户，并允许领域进行编辑，以更新。但是，当更新按钮的点击事件被触发时，这些字段将返回到其原始值。

这是我在C＃

protected void Page_Load(object sender, EventArgs e) 
{ 
    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(); 
} 

protected void UpdateDetailsButton_Click(object sender, EventArgs e) 
{ 
    SqlConnection conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["RaiseFantasyLeagueConnectionString"].ConnectionString); 
    SqlCommand cmd = new SqlCommand("[dbo].[UpdateUserDetails]", conn); 
    cmd.CommandType = CommandType.StoredProcedure; 

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

    TextBox FirstNameTextBox = (TextBox)Master.FindControl("ContentPlaceHolderMain").FindControl("FirstName"); 
    SqlParameter FirstNameParam = new SqlParameter("@ManagerFirstName", FirstNameTextBox.Text); 

    TextBox SurnameTextBox = (TextBox)Master.FindControl("ContentPlaceHolderMain").FindControl("Surname"); 
    SqlParameter SurnameParam = new SqlParameter("@ManagerSurname", SurnameTextBox.Text); 

    TextBox TeamNameTextBox = (TextBox)Master.FindControl("ContentPlaceHolderMain").FindControl("TeamName"); 
    SqlParameter TeamNameParam = new SqlParameter("@TeamName", TeamNameTextBox.Text); 

    TextBox TeamStadiumNameTextBox = (TextBox)Master.FindControl("ContentPlaceHolderMain").FindControl("StadiumName"); 
    SqlParameter TeamStadiumNameParam = new SqlParameter("@TeamStadium", TeamStadiumNameTextBox.Text); 

    TextBox EmailTextBox = (TextBox)Master.FindControl("ContentPlaceHolderMain").FindControl("Email"); 
    SqlParameter EmailParam = new SqlParameter("@Email", EmailTextBox.Text); 

    SqlParameter RecieveReminderParam = new SqlParameter("@RecieveReminder", 1); 

    SqlParameter RecieveSummaryParam = new SqlParameter("@RecieveSummary", 1); 
    cmd.Parameters.Add(userIDParam); 
    cmd.Parameters.Add(FirstNameParam); 
    cmd.Parameters.Add(SurnameParam); 
    cmd.Parameters.Add(TeamNameParam); 
    cmd.Parameters.Add(TeamStadiumNameParam); 
    cmd.Parameters.Add(EmailParam); 
    cmd.Parameters.Add(RecieveReminderParam); 
    cmd.Parameters.Add(RecieveSummaryParam); 

    conn.Open(); 
    cmd.ExecuteNonQuery(); 
    conn.Close(); 
}

而对于ASP

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolderMain" runat="server"> 
<div class="row"> 
    <div class="span12"> 
     <h3> 
      My Profile</h3> 
    </div> 
</div> 
<div class="row"> 
    <div class="span2"> 
     <label class="control-label" for="firstNameTextBox"> 
      First Name:</label> 
    </div> 
    <div class="span3"> 
     <asp:TextBox ID="FirstName" runat="server"></asp:TextBox> 
    </div> 
</div> 
<div class="row"> 
    <div class="span2"> 
     <label class="control-label" for="surnameTextBox" > 
      Surname:</label> 
    </div> 
    <div class="span3"> 
     <asp:TextBox ID="Surname" runat="server"></asp:TextBox> 
    </div> 
</div> 
<div class="row"> 
    <div class="span2"> 
     <label class="control-label" for="teamNameTextBox"> 
      Team Name:</label> 
    </div> 
    <div class="span3"> 
     <asp:TextBox ID="TeamName" runat="server"></asp:TextBox> 
    </div> 
</div> 
<div class="row"> 
    <div class="span2"> 
     <label class="control-label" for="stadiumNameTextBox"> 
      Stadium Name:</label> 
    </div> 
    <div class="span3"> 
     <asp:TextBox ID="StadiumName" runat="server"></asp:TextBox> 
    </div> 
</div> 
<div class="row"> 
    <div class="span2"> 
     <label class="control-label" for="emailTextBox"> 
      Email Address:</label> 
    </div> 
    <div class="span3"> 
     <asp:TextBox ID="Email" runat="server"></asp:TextBox> 
    </div> 
</div> 
<div class="row"> 
    <div class="span2"> 
     <label class="control-label" for="reminderCheckBox"> 
      Recieve Reminder Email:</label> 
    </div> 
    <div class="span3"> 
     <input type="checkbox" id="Reminder" runat="server"/> 
    </div> 
</div> 
<div class="row"> 
    <div class="span2"> 
     <label class="control-label" for="predictionCheckBox"> 
      Recieve Prediction Email:</label> 
    </div> 
    <div class="span3"> 
     <input type="checkbox" id="Prediction" runat="server"/> 
    </div> 
</div> 
<div class="row"> 
    <div class="span5"> 
     <asp:Button ID="UpdateDetailsButton" 
      CssClass="btn btn-primary rightAlignButton" runat="server" Text="Confirm" 
      onclick="UpdateDetailsButton_Click" /> 
    </div> 
</div>

我使用存储过程试图在SQL Management Studio中的代码和它的更新预期，所以出于某种原因，点击更新时字段没有读取更新的值。

任何建议将是伟大的，谢谢！

使用的IsPostBack在Page_Load事件

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(); 
}

它实际上如果（！Page.IsPostBack），但非常感谢！ – JackofAll 2013-03-15 17:31:35

您应该只在第一次从数据库加载数据，因此您必须检查它是否不是Postback。

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(); 
}
