Hi, I have also some trouble setting up binding with my form. this is what I have at the moment. when debugging. the properties are always null... ive tried adding the notifypropertychanged function in the xaml.cs but this didnt work.
XAML:
``
x:Class="DestinationsApp.AddDestinyPage">
<StackLayout Margin="10,10,10,0" BindingContext="{x:Binding Destiny}">
<Label Text="Add destiny" Margin="10" HorizontalTextAlignment="Center" FontSize="Title" TextColor="Black"/>
<Label Text="Country" FontSize="Title" TextColor="Black"/>
<Entry x:Name="eCountry" Text="{Binding Country, Mode=OneWay}"/>
<Label Text="City" FontSize="Title" TextColor="Black"/>
<Entry x:Name="eCity" Text="{Binding City,Mode=OneWay}"/>
<Label Text="Type" FontSize="Title" TextColor="Black"/>
<Picker x:Name="pType" SelectedItem="{Binding Type, Mode=OneWay}">
<Picker.Items>
<x:String>Appartment</x:String>
<x:String>Hotel</x:String>
<x:String>Camping</x:String>
</Picker.Items>
</Picker>
<Button x:Name="btnAddDestiny" Text="Add destiny" Clicked="btnAddDestiny_Clicked"/>
</StackLayout>
``
XAML.CS:
``
public partial class AddDestinyPage : ContentPage, INotifyPropertyChanged
{
private Destiny _Destiny;
public Destiny Destiny
{
get { return _Destiny; }
set { _Destiny = value; OnPropertyChanged(); }
}
public AddDestinyPage()
{
InitializeComponent();
Destiny = new Destiny();
//BindingContext = Destiny;
}
private async void btnAddDestiny_Clicked(object sender, EventArgs e)
{
if (string.IsNullOrWhiteSpace(Destiny.Country) ||
string.IsNullOrWhiteSpace(Destiny.City) ||
string.IsNullOrWhiteSpace(Destiny.Type))
{
}
}
}
``
Class:
``
public class Destiny : INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
private void OnPropertyChanged([CallerMemberName] String propertyName = "")
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
private string _ID;
public string ID
{
get { return _ID; }
set { _ID = value; OnPropertyChanged(nameof(ID)); }
}
private string _Country;
public string Country
{
get { return _Country; }
set { _Country = value; OnPropertyChanged(nameof(Country)); }
}
private string _City;
public string City
{
get { return _City; }
set { _City = value; OnPropertyChanged(nameof(City)); }
}
private string _Type;
public string Type
{
get { return _Type; }
set { _Type = value; OnPropertyChanged(nameof(Type)); }
}
}
