我已经通过我的代码查看是否存在任何空值,但每个人都带来了价值,但我找不到问题。
public partial class UserDetail : ICSBaseUserControl
{
UserRepository userDao = new UserRepository();
User user;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
long userID = Convert.ToInt64(Request[UrlParameters.UrlParameterName.UserID]);
user = (userID > 0) ? userDao.GetUser(AppSession.Company.ID, userID) : new c365_EntityFramework.User();
if (user.ID > 0)
{
txtFirstName.Text = user.Forename;
txtSurname.Text = user.Surname;
txtAddress.Text = user.Address1;
txtEmail.Text = user.Email;
txtUsername.Text = user.Username;
}
}
}
protected void Button2_Click(object sender, EventArgs e)
{
bool result = userDao.UpdateUser(user.ID, txtFirstName.Text, txtEmail.Text, txtSurname.Text, txtAddress.Text, txtUsername.Text);
}
}
编辑
这就是我修复它的方法,将user
加载移出if(!IsPostBack)
:
public partial class UserDetail : ICSBaseUserControl
{
UserRepository userDao = new UserRepository();
User user;
protected void Page_Load(object sender, EventArgs e)
{
long userID = Convert.ToInt64(Request[UrlParameters.UrlParameterName.UserID]);
user = (userID > 0) ? userDao.GetUser(AppSession.Company.ID, userID) : new c365_EntityFramework.User();
if (!IsPostBack)
{
if (user.ID > 0) // Check for user ID
{
txtFirstName.Text = user.Forename;
txtSurname.Text = user.Surname;
txtAddress.Text = user.Address1;
txtEmail.Text = user.Email;
txtUsername.Text = user.Username;
}
}
}
