How to capture a date in Xamarin and process it in ShellView.xaml.cs file RRS feed

  • Question

  • Greetings

    I am building a WPF UI that captures date of birth and adds it to PersonType object so it can be inserted into an instance of MongoDB. I am using Caliburn.Micro also and I get compiler errors when I try to extend the Screen class and when I want to use NotifyOfPropertyChange(); it says Notify... does not exist in the current context. I get another compiler error under ShellView which says: "Partial declarations of ShellView must not specify different base classes."

    public partial class ShellView : Screen
            MongoCRUD da = new MongoCRUD("mongoChallenge");

            PersonModel newPerson = new PersonModel();
            private List<PersonModel> _people;

            public List<PersonModel> People
                get { return _people; }
                    _people = value;

            public ShellView()
            private void SubmitButton_Click(object sender, RoutedEventArgs e)

            private void NewPerson_Click(object sender, RoutedEventArgs e)
                newPerson.FirstName = firstName.Text;
                newPerson.LastName = lastName.Text;
                List<PersonModel> People = new List<PersonModel>();
                AddressModel newAddress = new AddressModel();
                newAddress.StreetAddress = StreetAddress.Text;
                newAddress.City = City.Text;
                newAddress.State = State.Text;
                newAddress.ZipCode = ZipCode.Text;
                newPerson.PrimaryAddress = newAddress;
                da.InsertRecord<PersonModel>("challengeUsers", newPerson);
                People = da.LoadRecords<PersonModel>("mongoChallenge");

            private void DateOfBirth_SelectedDateChanged(object sender, SelectionChangedEventArgs e)
                newPerson.DateOfBirth = dateOfBirth.DisplayDate;
    <Label Grid.Row="5" Grid.Column="0">
                Enter the first name:
            <TextBox Grid.Row="5" Grid.Column="1" MinWidth="100"
               Name="firstName" Margin="0,0,0,0"/>

            <Label Grid.Row="6" Grid.Column="0" >
                Enter the last name:
            <TextBox Grid.Row="6" Grid.Column="1" MinWidth="100"
               Name="lastName" Margin="0,0,0,0"/>
            <Label Grid.Row="7" Grid.Column="0">Date of Birth</Label>
            <DatePicker Grid.Row="7" Grid.Column="7" Name="dateOfBirth"/>
            <Label Grid.Row="8" Grid.Column="0">Street Address</Label>
            <TextBox Grid.Row="8" Grid.Column="1" Name="StreetAddress" Margin="0,0,0,0" MinWidth="100"/>
            <Label Grid.Row="9" Grid.Column="0">City</Label>
            <TextBox Grid.Row="9" Grid.Column="1" Name="City" Margin="0,0,0,0" MinWidth="100"/>
            <Label Grid.Row="10" Grid.Column="0">State</Label>
            <TextBox Grid.Row="10" Grid.Column="1" Name="State" Margin="0,0,0,0" MinWidth="100"/>
            <Label Grid.Row="11" Grid.Column="0">ZipCode</Label>
            <TextBox Grid.Row="11" Grid.Column="1" Name="ZipCode" Margin="0,0,0,0 " MinWidth="100"/>
            <Button Grid.Row="12" Grid.Column="0" x:Name="NewPerson"
              Margin="2" Click="NewPerson_Click">
                Submit New Person

            <Button Grid.Row="13" Grid.Column="0" 
              Name="Clear" Margin="2">
                Clear Name

  • Hi,

    Since the problem is more related to Xamarin, it is out of the scope of UWP apps, I suggest that you might need to ask about this in the Xamarin's official forum.
