 # How to show empty message when listview has no items in xamarin forms
 This example demonstrates to show empty message when listview has no items by using the visibility property.
 
+## Sample
+
+```xaml
+<Grid Padding="{OnPlatform iOS='0,40,0,0'}">
+    <Grid.RowDefinitions>
+        <RowDefinition Height="50"/>
+        <RowDefinition Height="*"/>
+    </Grid.RowDefinitions>
+    <Button x:Name="ItemSource" Grid.Row="0" 
+            Text="Change ItemSource" 
+            HorizontalOptions="CenterAndExpand"
+            VerticalOptions="CenterAndExpand" 
+            Command="{Binding OnItemsSourceChanged}"/>
+    <Grid IsVisible="{Binding IsVisible}" Grid.Row="1">
+        <Label x:Name="label"
+                Text = "No Items :(" 
+                FontSize ="Default"
+                HorizontalOptions = "FillAndExpand"
+                HorizontalTextAlignment = "Center"
+                VerticalTextAlignment = "Center"
+                VerticalOptions = "FillAndExpand"/>
+    </Grid>
+    <syncfusion:SfListView x:Name="listView" Grid.Row="1"  ItemsSource="{Binding ContactsInfo}"
+                        IsVisible="{Binding Path=IsVisible, Converter={StaticResource visibilityConverter}}"
+                        ItemSpacing="2" ItemSize="30">
+        <syncfusion:SfListView.ItemTemplate>
+            <DataTemplate>
+                <Label Text="{Binding ContactName}"/>
+            </DataTemplate>
+        </syncfusion:SfListView.ItemTemplate>
+    </syncfusion:SfListView>
+</Grid>
+```
