I have a Xamarin Forms project and I'm trying to show frame shadow just like this
But instead it shows like this, the shadow is only appearing on the corners
I can't get it to show everywhere like the first picture
Here is my code:

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

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.

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.
Uisng the carsoule view I am trying to list planes for the msfs community however the image is very small.
<CollectionView x:Name="addOnList" Margin="0,40,0,0" Grid.Row="1" SelectionMode="Single"

<CollectionView.ItemsLayout>
<GridItemsLayout Orientation="Vertical" VerticalItemSpacing="20" HorizontalItemSpacing="20" Span="2"/>
</CollectionView.ItemsLayout>

<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Image Aspect="Fill" Source="{Binding ThumbNail}" Margin="10" WidthRequest="200" HeightRequest="200"

<Label Grid.Row="1" Text="{Binding Name}" TextColor="#F9B522" FontFamily="ThemeFont"
VerticalOptions="End" HorizontalOptions="Start"/>
<Label Grid.Row="1" Text="{Binding Version}" TextColor="White" FontFamily="ThemeFont"
VerticalOptions="End" HorizontalOptions="End"/>
<Button Grid.Row="3" x:Name="btnSetReminder" Text="Add to Favourites"></Button>
</Grid>
</DataTemplate>
</CollectionView.ItemTemplate>
<CollectionView.Footer>
<Grid HeightRequest="0"/>
</CollectionView.Footer>
</CollectionView>
What I want is Image Name over the image then I want a button to say add to favourites which would be a heart and then a the version number to the right something like this but I would like the title to be over the image and the image to be slightly bigger
The whole Grid has a HeightRequest 160 and you image can't get the HeightRequest="200".
Also the Button should in Grid.Row 2.
I would recommend you to layout this way:
<CollectionView.ItemTemplate>
<DataTemplate>
<Grid Padding="10" BackgroundColor="#131313" WidthRequest="145" HeightRequest="160">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="20"/>
<RowDefinition Height="50"/>
</Grid.RowDefinitions>
<Image Aspect="Fill" Source="sample.jpg"
HorizontalOptions="Center" VerticalOptions="Center"/>
<Label Grid.Row="1" Text="Name" TextColor="#F9B522" FontFamily="ThemeFont"
VerticalOptions="End" HorizontalOptions="Start"/>
<Label Grid.Row="1" Text="Version" TextColor="White" FontFamily="ThemeFont"
VerticalOptions="End" HorizontalOptions="End"/>
<Button Grid.Row="2" x:Name="btnSetReminder" Text="Add to Favourites"></Button>
</Grid>
</DataTemplate>
</CollectionView.ItemTemplate>
Here is the result:
Update:
<CollectionView.ItemTemplate>
<DataTemplate>
<Grid Padding="10" BackgroundColor="#131313" WidthRequest="145" HeightRequest="160">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="20"/>
<RowDefinition Height="50"/>
</Grid.RowDefinitions>
<Image Aspect="Fill" Source="sample.jpg"
HorizontalOptions="Center" VerticalOptions="Center"/>
<Label Grid.Row="1" Text="Name" TextColor="#F9B522" FontFamily="ThemeFont"
VerticalOptions="End" HorizontalOptions="Start"/>
<Label Grid.Row="1" Text="Version" TextColor="White" FontFamily="ThemeFont"
VerticalOptions="End" HorizontalOptions="End"/>
<StackLayout Grid.Row="2" Orientation="Horizontal">
<Button Text="left" FontSize="8" HorizontalOptions="Start" WidthRequest="50"></Button>
<Button x:Name="btnSetReminder" FontSize="8" Text="Add to Favourites" HorizontalOptions="FillAndExpand"></Button>
<Button Text="right" FontSize="8" HorizontalOptions="End" WidthRequest="50"></Button>
</StackLayout>
</Grid>
</DataTemplate>
</CollectionView.ItemTemplate>
To enlarge the image and make the text and button overlay:
<Image Grid.RowSpan="3" ... />
For a heart-favourite button, please try ImageButton:
<ImageButton Source="heart.png" ... />

Image is available in Resource Folder.
I have also face same issue and solved.
Try this Hope it will Help..
You could use a Relative layout to achieve the results
<RelativeLayout>
<Image Source="masterpagebg.png" Opacity="1"
RelativeLayout.WidthConstraint=
"{ConstraintExpression Type=RelativeToParent, Property=Width}"
RelativeLayout.HeightConstraint=
"{ConstraintExpression Type=RelativeToParent, Property=Height}"/>
<ListView RelativeLayout.WidthConstraint=
"{ConstraintExpression Type=RelativeToParent, Property=Width}"
RelativeLayout.HeightConstraint=
"{ConstraintExpression Type=RelativeToParent, Property=Height}" x:Name="MenuItemsListView" WidthRequest="200"
HasUnevenRows="true"
ItemsSource="{Binding MenuItems}"
SeparatorColor="White">
<ListView.Header>
<Grid >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="10"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="10"/>

<RowDefinition Height="80"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="10"/>
</Grid.RowDefinitions>
<Image Source="logo.png" Grid.Row="1" Grid.Column="1"></Image>

TextColor="White"

</StackLayout>
</ViewCell>

You should check if the image is set to the iOS project as BundleResource, if not you should set it as so. I myself had some troubles with this.
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.
