How to overlay Lottie animation on top of stacklayout Xamarin

I have an invoice page in my Xamarin project where I want to display a Lottie animation each time an invoice is deleted. The issue is that the animation shows if there is nothing else on the page but when I try to overlay it doesn't show.
Here is the xaml code

</Grid>
</ContentPage.Content>
</ContentPage>
To achieve that overlay I just assigned the property Grid.Row="0" to both,the StackLayout that contains the invoice list and the one that contains the animation.
For context here's the view
Also, it has a weird behaviour, when I change the Grid.Row property to 1 and then back to 0 it does show. But at first it doesn't.
Please help and thanks.

What can I do to show the shadow all around the frame? Please help and thanks.
EDIT
This is what I have with Margin=2 on Frame
Margin=50
Padding=50
Just to show how it behaves

At first, you can create a new frame in your project to check if the cause is the renderer or not. Such as:
<Frame Margin="20" CornerRadius="10" HasShadow="True">
<Label Text="TestShaw" HorizontalOptions="Center"/>
</Frame>
If the shadow shows correctly, the cause maybe the layout or the margin of your frame. So you can change the values of it.
If the shadow shows incorrectly too, you may need to use a custom renderer for the frame. Such as:
[assembly: ExportRenderer(typeof(Myframe), typeof(MyFrameRenderer))]
namespace App36.Droid
{
public class MyFrameRenderer : Xamarin.Forms.Platform.Android.FastRenderers.FrameRenderer
{
public MyFrameRenderer(Context context) : base(context)
{
}
protected override void OnElementChanged(ElementChangedEventArgs<Frame> e)
{
base.OnElementChanged(e);
CardElevation = 50;
SetOutlineSpotShadowColor(Xamarin.Forms.Color.Black.ToAndroid());
SetOutlineAmbientShadowColor(Xamarin.Forms.Color.Black.ToAndroid());
}
}
}
But in my project, both of them shows correctly. So if you need more information, you can check the link following.
Link: Xamarin forms Shadow on Frame in Android
And here is the frame in my project:
If the platform is ios for your project, please check this case:Forms frame isn't the same on iOS

call variable from codebehind inside DataTemplate with Xamarin Forms

It would recover from the codebehind firstGrid and secondGrid objects.
But these are inside a DataTemplate, as I can recall them from the codebehind?

Warning: Before that is duplicated, the code is for Xamarin forms pcl. Which it is slightly different from c # with WPF.
thanks

When you use a DataTemplate, the binding concern the object you are binding and not the ViewModel you may have used.
But fear not, as Xamarin provides us ways to attach treatements to this kind of objects !
Let's say you want to click your image :
<Button Image="nextBlueArrow.png" BorderColor="Transparent" BackgroundColor="Transparent" Clicked="clickmeNext" Grid.Column="3"></Button>
May become
<Image Source="nextBlueArrow.png">
<Image.GestureRecognizers>
<TapGestureRecognizer
Tapped="clickmeNext"
CommandParameter="{Binding .}" />
</Image.GestureRecognizers>
</Image>
With the clickmeNext method in your code behind like this :
public async void clickmeNext(object sender, EventArgs e)
{
Image imageSender = (Image)sender;
YourObject yourObject= (YourObject )imageSender.BindingContext;
//some actions on your instance of YourObject,
//which is the instance linked to the image
}
If I did not answer your question, don't hesitate to add to your question to make it more clear.

There are plenty of samples and controls out there. You don't really need to do it yourself. Syncfusion offers some nice controls for Xamarin. There is a free Community License too.
I think that's what you want -> https://www.syncfusion.com/products/xamarin
