Support binding Actions to Commands programmatically

[daawaan4U]

I have a ViewModel that has an ICommand property and would like to initialize the binding of that command property to a method using Actions in the ViewModel.

Something like:

public class Page : Screen, INavigationPage
{
    public ICommand Command => (ICommand)(new Action((PublishMyEvent)));
    . . .
    public void PublishMyEvent() => eventAggregator.Publish(new MyEvent());
}

Why not use actions?

I mean yeah, I'm referring to the Actions from this framework. It's just that the examples are done in xaml. Does the framework provide a way to do it in code?

I'm binding the Command property above in a style for an ItemsControl inside a CustomControl.

 . . .
<Style TargetType="{x:Type ItemsControl}">
    <Setter Property="ItemTemplate">
        <Setter.Value>
            <DataTemplate>
                <local:Item Command="{Binding Command}" Icon="{Binding Icon}" />
            </DataTemplate>
        </Setter.Value>
    </Setter>
</Style>
. . . 

Since the {s:Action MethodName} doesn't work in Styles, I'm finding a way if Stylet's action can work in code-behind. Something similar to my first comment.

Ah right. You'll have to write your own ICommand implementation. They're pretty straightforward.
