Here is my App.xaml.cs
protected override Task OnInitializeAsync(IActivatedEventArgs args) {
Container.RegisterInstance(SessionStateService);
Container.RegisterInstance(NavigationService);
Container.RegisterType<IUserRepository, UserRespository>(new ContainerControlledLifetimeManager());
Container.RegisterType<UserSettingsContext>(new ContainerControlledLifetimeManager());
Container.RegisterType<IUserSettings, UserSettings>(new ContainerControlledLifetimeManager());
var userSettings = this.Container.Resolve<UserSettingsContext>();
userSettings.Database.EnsureCreated();
return base.OnInitializeAsync(args);
}
This is my UserSettings
using using Prism.Windows.Validation;
public class UserSettings : ValidatableBindableBase, IUserSettings {
private string _firstName;
public string FirstName {
get { return _firstName; }
set { SetProperty(ref _firstName, value); }
}
private string _lastName;
public string LastName {
get { return _lastName; }
set { SetProperty(ref _lastName, value); }
}
private UserType _userType;
public UserType UserType {
get { return _userType; }
set { SetProperty(ref _userType, value); }
}
private string _username;
[Required(ErrorMessage = "Required.")]
public string Username {
get { return _username; }
set { SetProperty(ref _username, value); }
}
private string _password;
[Required(ErrorMessage = "Required.")]
public string Password {
get { return _password; }
set { SetProperty(ref _password, value); }
}
}
ViewModel:
public class TestViewModel : UserSettings {
private UserSettings user;
public UserSettings User => user;
public async void SaveSettings() {
//It will work with this line
// var user = new UserSettings() {
// Username= this.Username,
// Password= this.Password,
// UserType= this.UserType,
// FirstName= this.FirstName,
// LastName= this.LastName
// };
//null properties
await loginService.SaveUserSettings(user);
}
}
When I tried to pass the 'user' the properties are null ,even user input data from UI(View), It will work if I setup the UserSettings using the code above, but I want to simplify this without that, how can I do that?
Thanks
You want to write await loginService.SaveUserSettings(this); because this seems to be the target that's filled with data.

I am trying to reach a foreach but my program never gets inside because my ICollection Coletores is always empty even if I put a lot of stuff in there.
The code where I want to get inside and it is always empty (I want to get inside the second foreach):
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
if (NavigationContext.QueryString.TryGetValue("email", out email))
{
//MessageBox.Show(email);
List<HyperlinkButton> listaLinks = new List<HyperlinkButton>();
AppDataContext db = new AppDataContext();
int i = 0;
HyperlinkButton aux = new HyperlinkButton();
foreach (Pessoa pessoa in db.Pessoas)
{
if (pessoa.Email == email)
{
foreach (Coletor coletor in pessoa.Coletores)
{
aux.Content = "Coletor " + (i + 1).ToString();
aux.FontSize = 24;
aux.NavigateUri = new Uri("/OcorrenciasPage.xaml?coletorId=" + coletor.Id.ToString(), UriKind.RelativeOrAbsolute);
listaLinks.Add(aux);
i++;
}
}
}
ListBox coletores = new ListBox();
coletores.ItemsSource = listaLinks;
stcList.Children.Add(coletores);
}
base.OnNavigatedTo(e);
}
Now the code that I am adding data:
if (txtLat.Text != "" && txtLong.Text != "" && rdNorte.IsChecked == true || rdSul.IsChecked == true && rdLeste.IsChecked == true || rdOeste.IsChecked == true)
{
foreach (var pessoa in db.Pessoas)
{
if (pessoa.Email == email)
{
pessoa.Coletores.Add(coletor);
}
}
db.Coletores.InsertOnSubmit(coletor);
db.SubmitChanges();
NavigationService.Navigate(new Uri("/ColetoresPage.xaml?email=" + email, UriKind.RelativeOrAbsolute));
}

The Coletores property on the Pessoa class looks alright. There is also a PessoaColetores property. Are you sure there has been no confusion between the two? Especially with intellisense one might dot or tab the wrong one.
Have you put a break point on the line that actually adds coletors (second code snippet)? Maybe stuff is added to the wrong collection.
Cheers, B.
I have this Business Layer/ Contactentry.ascx page which calls a stored prcoedure to insert data into sql database and then the page below calls this business layer method. the issue is this method
aspdotnet.BusinessLogicLayer.ContactEntry AddEntry =
new ContactEntry(Convert.ToInt32(Session["ContactID"].ToString())
,Title,FirstName,MiddleName,LastName,JobTitle,Company,Website,OfficePhone
,HomePhone,Mobile,Fax,OEmail,PEmail,OAStreet,OACity,OAState,OACountry
,OAZipCode,PAStreet,PACity,PAState,PACountry,PAZipCode);
throws an error saying object refernece not set to an instance of an object although I have entered all values for the text fields.

Insert form calling above function from Business Layer:

//AddEntry.Save();
}
I get object reference not set to an insance of object right after above method aspdotnet.BusinessLogicLayer.ContactEntry above. I see all values are being passed when I am debugging. I entered all values when entering values above but it still errors out. Not sure what I am missing. Please help , appreciate your time.
This line is suspicious:
Convert.ToInt32(Session["ContactID"].ToString())
Session["ContactID"] may return null and calling ToString() on null blows up. Convert.ToInt32(null) wouldn't throw an error - it would return 0, not NULL.
You to handle Session["ContactID"] for nulls and Empty before Converting it to Int32
Example :
ContactEntry cEntry = null;
if(Session["ContactID"] != null)
{
if(!String.IsNullOrEmpty(Session["ContactID"]))
{
cEntry = new ContactEntry(Convert.ToInt32(Session["ContactID"].ToString());
}
}
Check your Session["ContactID"].
Consider changing your code to something like this...
//...
string PAState = this.txtPAState.Text;
string PACountry = this.txtPACountry.Text;
string PAZipCode = this.txtPAZipCode.Text;
string contactIDstr = Session["ContactID"] as string;
int contactID = 0;
if(!String.IsNullOrEmpty(conactIDStr))
Int32.TryParse(contactIDStr, out contactID);
aspdotnet.BusinessLogicLayer.ContactEntry AddEntry = new ContactEntry(
contentID,
Title,
FirstName,MiddleName,LastName,JobTitle,Company,
Website,OfficePhone,HomePhone,Mobile,Fax,OEmail,PEmail,
OAStreet,OACity,OAState,OACountry,OAZipCode,PAStreet,PACity,PAState,PACountry,PAZipCode
);
