我有一个Login控件，其中我添加了一个额外的文本框，我想在登录时将日期时间，用户名和文本框数据保存到数据库中（登录时没有任何问题）。日期时间正在保存，但用户名和文本框文本未保存。下面是我的aspx.cs代码： -
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
TextBox Txt = (TextBox)Login1.FindControl("TextBox1"); //Login1 is loginID and TextBox1 is textbox ID
if (Txt != null)
{
Txt.Focus();
}
if ((Session["Check"] != null) && (Convert.ToBoolean(Session["Check"]) == true))
{
// If User is Authenticated then
if (User.Identity.IsAuthenticated)
//call the method to execute insert to the database
ExecuteInsert(Txt.Text,
DateTime.Now,
Login1.UserName); //Login1 is login ID
}
}
if (!this.IsPostBack)
ViewState["LoginErrors"] = 0;
}
插入方法：
private void ExecuteInsert(string AuditorComments, DateTime AuditDate, string Auditor)
{
SqlConnection conn = new SqlConnection("Data Source = usftdl0008; Initial Catalog = *******;Persist Security Info=True;User ID=*****;Password=*****; Integrated Security = TRUE");
string sql = "UPDATE TBLhsCaser SET AuditorComments = @AuditorComments, AuditDate = @AuditDate, Auditor = @Auditor WHERE AuditDate IS NULL ";
try
{
conn.Open();
SqlCommand cmd = new SqlCommand(sql, conn);
SqlParameter[] param = new SqlParameter[3];
//param[0] = new SqlParameter("@id", SqlDbType.Int, 20);
param[0] = new SqlParameter("@AuditorComments", SqlDbType.VarChar, 50);
param[1] = new SqlParameter("@AuditDate", SqlDbType.DateTime, 50);
param[2] = new SqlParameter("@Auditor", SqlDbType.VarChar, 50);
param[0].Value = AuditorComments;
param[1].Value = AuditDate;
param[2].Value = Auditor;
for (int i = 0; i < param.Length; i++)
{
cmd.Parameters.Add(param[i]);
}
cmd.CommandType = CommandType.Text;
cmd.ExecuteNonQuery();
}
catch (System.Data.SqlClient.SqlException ex)
{
string msg = "Insert Error:";
msg += ex.Message;
throw new Exception(msg);
}
finally
{
conn.Close();
}
}

使用此代码检索登录用户的用户名：
MembershipUser u;
string uname;
u = Membership.GetUser();
uname = u.UserName;
请注意，我通常不会使用C＃编码，因此您可能需要稍微调整上述代码。
关于textbox1控件，您是否检查过呈现的页面以查看 textbox1 是否仍然是控件的ID？ ASP毕竟动态呈现这些ID。尝试将此属性作为属性添加到控件中，并查看当前代码是否有效：
ClientIDMode="Static"
