Xamarin ContentView renderer hides Content

I have such class:

          public class MetroButton: ContentView
        {

            public MetroButton ()
            {
                //create and filling mainGrid
                this.Content = mainGrid;
            }
        }

This works ok. But when i renderer my ContentView (MetroButton) - content not displayed (Content disappears , there remains only the main control).

My Render:

[assembly: ExportRenderer (typeof(MetroButton), typeof(RendererToClickView))]

...

public class RendererToClickView:ViewRenderer
{
    public RendererToClickView ()
    {

    }
}

You don't need to create a FrameRenderer for this. The renderer of a ContentView is a ViewRenderer, as can be seen in the link:

You can do something like this:

[Assembly: ExportRenderer (typeof (ImageGallery), typeof (ImageGalleryRenderer))]
Namespace MRV.AppClient.Mobile.Droid.CustomRenderers
{
     Class ImageGalleryRenderer: ViewRenderer
     {
         Protected override void JavaFinalize ()
         {
             ImageService.Instance.InvalidateMemoryCache ();
             Base.JavaFinalize ();
         }
     }
}

There's no ContentViewRenderer. Try to use FrameRenderer and just disable border drawing. That works good (tried it by myself).

    public class MyFrame : Frame
    {
        public MyFrame()
        {
            Content = new Label() {
                Text = "Test"
            };
            BackgroundColor = Color.Transparent;
            OutlineColor = Color.Transparent;
        }
    }

[assembly: ExportRenderer (typeof (MyFrame), typeof (MyFrameRenderer))]
namespace YourAssembly.Droid
{
    public class MyFrameRenderer : FrameRenderer
    {
        public MyFrameRenderer()
        {

        }
    }
}
