This is my carView

	<ContentView.Content>

			       CornerRadius="5"

				                     HorizontalOptions="Start"

				                     WidthRequest="30" />  
				<Label Margin="0,0,7,0"  
				       FontAttributes="Bold"  
				       Text="{Binding Name}"  
				       VerticalTextAlignment="Center" />  
			</StackLayout>  
  
  
		</Grid>  
	</ContentView.Content>  
</ContentView>  

the problem is that when I delete, I can see a huge gap in the elements

How can I get rid of the gap?
