Xamarin Forms Right align button in a Grid - xamarin

Question

I'm using a Grid with 7 rows and 3 columns. I added a button to the 7th row and 3rd column like this:
<Button Grid.Row="6" Grid.Column="2" HorizontalOptions="End"/>
The problem is the button is always in the center. I can't seem to get it to go to the end.
Here's the structure
<Image Aspect="AspectFit" HeightRequest="60" Grid.Row="0" Grid.Column="0" Grid.RowSpan="3" Source="{Binding ProdImg}" />
<Label Grid.Row="0" Grid.Column="1" HorizontalOptions="Start" TextColor="White" FontSize="22" Text="{Binding UserName}"/>
<Label HorizontalOptions="End" Grid.Row="0" Grid.Column="2" TextColor="#b1fc03" FontSize="25" Text ="{Binding Sales, StringFormat='{0:#,#.}'}"/>
<Label Grid.Row="1" Grid.Column="1" HorizontalOptions="Start" TextColor="White" FontSize="10" Text="{Binding LastSale, StringFormat='{0:dd-MMM-yyyy}'}"/>
<Label HorizontalOptions="End" Grid.Row="1" Grid.Column="2" TextColor="White" FontSize="10" Text="{Binding ProdName}"/>
<Button x:Name="TryNowBtn" HorizontalOptions="End" Image="try-now.png" Grid.Row="2" Grid.Column="2"></Button>
</Grid>
</StackLayout>
<Image Aspect="AspectFit" Source="separator-line.png"/>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
I also tried
View.HorizontalOptions="End"

Answer 1

chagne your column definition to this
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
for button this code is ok
<Button Grid.Row="6" Grid.Column="2" HorizontalOptions="End"/>
