How pass the current data with converter? - xamarin.forms

Question

How can i send the current element of my Actors list to my converter? and as well i need pass a parameter with ConverterParameter
<ListView x:Name="Actors" ItemsSource="{Binding Actors}">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<ViewCell.ContextActions>
Source="" IsVisible="{Binding ., Converter={StaticResource ListConverter}, ConverterParameter={Binding ActorCurrent}}"}"/>
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
this Actor exist in my view movel, i need to pass as parameter
private Actor _actorCurrent;
public Actor ActorCurrent
{
get => _actorCurrent;
set
{
_actorCurrent = value;
RaisePropertyChanged(() => ActorCurrent);
}
}
i tried with dot, but dont work
IsVisible="{Binding . // in my Converter class i dont nothing
EDIT 1:
i have as well this
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
// i want to value = will be {Binding .,
// and parameter = will be ActorCurrent
// then i want to compare value with parameter and return a bool
}
Or can i use triggers?
<DataTrigger TargetType="Image" Binding="{Binding Name}" Value="{Binding ActorCurrent.name}">

Answer 1

i want to value = will be {Binding .}
You can get the value in the Convert method, you have to know the type of your value first. You can add a breakpoint there to get the type of value:
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
//if the type of value is Actor:
Actor tempActor = value as Actor;
//if the type of value is string:
string tempStr = value as string
return "123";
}
and parameter = will be ActorCurrent
Actually, you can't set binding to ConverterParameter as ConverterParameter is not a BindableProperty.
There is a discussion about this problem in this thread and you may find some idea there.
