How to get value of swiped card view xamarin - xamarin

Question

I have a SwipeCardView and I want to get the id of the user that I've just swiped.
<swipeCardView:SwipeCardView
x:Name="SwipeView1" ItemsSource="{Binding Profiles}" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand"
Padding="10" >
<swipeCardView:SwipeCardView.ItemTemplate>
<DataTemplate>
<StackLayout HorizontalOptions="FillAndExpand"
VerticalOptions="FillAndExpand">
<Frame CornerRadius="10"
Padding="8"
HorizontalOptions="FillAndExpand"
VerticalOptions="FillAndExpand">
<AbsoluteLayout>
<AbsoluteLayout.GestureRecognizers>
<SwipeGestureRecognizer Direction="Left" Command="{Binding LeftCommand}"
CommandParameter="{Binding nome}" />
</AbsoluteLayout.GestureRecognizers>
<Image Source="{Binding foto_perfil}"
Aspect="AspectFill"
AbsoluteLayout.LayoutBounds=".5,0.5,1,1"
AbsoluteLayout.LayoutFlags="All" />
<Label FontSize="Large"
WidthRequest="30"
FontAttributes="Bold"
TextColor="White"
BackgroundColor="Black"
AbsoluteLayout.LayoutBounds="0.1,0.95,250,30"
AbsoluteLayout.LayoutFlags="PositionProportional">
<Label.FormattedText>
<FormattedString>
<Span Text="{Binding nome}" />
<Span Text=", " />
<Span Text="{Binding data_nasc}" />
</FormattedString>
</Label.FormattedText>
</Label>
</AbsoluteLayout>
</Frame>
</StackLayout>
</DataTemplate>
</swipeCardView:SwipeCardView.ItemTemplate>
</swipeCardView:SwipeCardView>
In the C# I created a command but it never enter i the void:
public Command LeftCommand => new Command<string>(LeftSwipe);
void LeftSwipe(string parameter)
{
var variable = parameter; //= breed_Name
DisplayAlert("", variable.ToString(), "ok");
}
I don´t know what I've done wrong because it still swipes

If your LeftCommand is in the ViewModel of your page, you can specify a source just as Jason said.
You can refer to the folloing code:
<swipeCardView:SwipeCardView x:Name="mCardView"
ItemsSource="{Binding CardItems}"
VerticalOptions="FillAndExpand">
<swipeCardView:SwipeCardView.ItemTemplate>
<DataTemplate>
<StackLayout >
<Label Text="{Binding Name}" FontSize="Large" HorizontalTextAlignment="Center" VerticalTextAlignment="Center" BackgroundColor="Beige" />
<StackLayout.GestureRecognizers>
<SwipeGestureRecognizer Direction="Left"
Command="{Binding Path=BindingContext.LeftCommand, Source={x:Reference mCardView}}"
CommandParameter="{Binding .}" >
</SwipeGestureRecognizer>
</StackLayout.GestureRecognizers>
</StackLayout>
</DataTemplate>
</swipeCardView:SwipeCardView.ItemTemplate>
</swipeCardView:SwipeCardView>
Note:
1.mCardView is the x:Name="mCardView" of your SwipeCardView;
2.In your viewModel, you can get the Binded Item as follows:
public Command LeftCommand => new Command(LeftSwipe);
void LeftSwipe(Object parameter)
{
//You can change `Profile ` to your Item Model
Profile variable = parameter as Profile;
System.Diagnostics.Debug.WriteLine("-----------> " + variable.Name +"<---> Id = "+ variable.ProfileId);
}
