Ivalue Converter Property in Xamarin - xaml

Question

I have the following converter that takes two properties :
public class ProgressConverter : BindableObject, IMarkupExtension, IValueConverter
{
public static readonly BindableProperty CurrentProgressProperty = BindableProperty.Create("CurrentProgress", typeof(int), typeof(ProgressConverter));
public static readonly BindableProperty GoalProgressProperty = BindableProperty.Create("GoalProgress", typeof(int), typeof(ProgressConverter));
public int CurrentProgress
{
get { return(int) GetValue(CurrentProgressProperty); }
set { SetValue(CurrentProgressProperty, value);}
}
public int GoalProgress
{
get { return (int)GetValue(GoalProgressProperty); }
set { SetValue(GoalProgressProperty, value);}
}
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
double progress = (double)CurrentProgress / (double)GoalProgress;
return progress;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
public object ProvideValue(IServiceProvider serviceProvider)
{
//throw new NotImplementedException();
return this;
}
object IMarkupExtension.ProvideValue(IServiceProvider serviceProvider)
{
return ProvideValue(serviceProvider);
}
}
and I am using it inside progressbar to set progress like this (this works fine no problem , will take 2 and divide it by 5 then put the results into progressbar progress ):
<ProgressBar x:Name="Progressbar" ProgressColor="Purple"
Progress="{Binding Converter={local:ProgressConverter CurrentProgress=1,GoalProgress=5}}">
</ProgressBar>
But when I do this , it wont work (Point#1) : (the value for both CurrentProgress and GoalProgress inside the converter are 0).
<ProgressBar x:Name="Progressbar" ProgressColor="Purple"
Progress="{Binding Converter={local:ProgressConverter CurrentProgress={Binding xCurrentProgress},GoalProgress={Binding xGoalProgress}}}">
</ProgressBar>
Both xCurrentProgress and xGoalProgress are set in the parent itemSource .
Model :
public class badge {
string Name {get;set;}
string Description {get;set;}
int xCurrentProgress {get;set;}
int xGoalProgress {get;set;}
}
Itemsource setting :
public BadgeView(BadgesGroup badgesGroup)
{
InitializeComponent();
BadgeLogo.Source = badgesGroup.Logo;
var cardsview = new CardsView
{
IsClippedToBounds = true,
IsCyclical = true,
MoveWidthPercentage = 0.3,
WidthRequest = 250,
HeightRequest=250,
ItemsSource = badgesGroup.Badges,
ItemTemplate = new DataTemplate(() => new BadgePopUp())
};
cardsview.Children.Add(new IndicatorsControl());
cardsview.Children.Add(new RightArrowControl());
cardsview.Children.Add(new LeftArrowControl());
card.Children.Add(cardsview);
}
How do I make it work for point#1
How can I make the converter takes values from binding like this :
<ProgressBar x:Name="Progressbar" ProgressColor="Purple"
Progress="{Binding Converter={local:ProgressConverter CurrentProgress={Binding xCurrentProgress},GoalProgress={Binding xGoalProgress}}}">
</ProgressBar>
Because using above code would result both values of CurrentProgress and GoalProgress pass 0 not the actual value stored in them .
