ListView defined as follows:
<syncfusion:SfListView
Margin="2"
BackgroundColor="White"
HorizontalOptions="FillAndExpand"
ItemSize="150"
ItemSpacing="0,0,10,0"
ItemsSource="{Binding Books}"
VerticalOptions="CenterAndExpand"
Padding="0">
<syncfusion:SfListView.ItemsLayout>
<syncfusion:GridLayout SpanCount="4" />
</syncfusion:SfListView.ItemsLayout>
<syncfusion:SfListView.ItemTemplate>
<DataTemplate>
<Border
Margin="0,0,10,0"
Padding="0"
Stroke="Black"
StrokeShape="RoundRectangle 5"
StrokeThickness="3"
HorizontalOptions="Center">
If the right margin of the 'Border' is set to a value below the value for the right ItemSpacing, then the right edge of the border is clipped. To test, set the ItemSpacing="0,0,15,0". This now clips 5 from the right hand edge of the border. I have not tested on other platforms, this is on Windows.
