Sometimes we want to change the style of multiple controls. The following example demonstrates how to define a custom style for some of the labels of our form.
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="App1.Page1">
<ContentPage.Resources>
<ResourceDictionary>
<Style x:Key="labelStyle" TargetType="Label">
<Setter Property="HorizontalOptions" Value="Center" />
<Setter Property="VerticalOptions" Value="CenterAndExpand" />
<Setter Property="TextColor" Value="Red" />
<Setter Property="FontSize" Value="Large" />
</Style>
</ResourceDictionary>
</ContentPage.Resources>
<StackLayout>
<Label x:Name="MyLabel" Text="Hello World!" Style="{StaticResource labelStyle}" />
</StackLayout>
</ContentPage>
We created a resource dictionary which has the key name labelStyle which has to be assigned to the label controls that we want to use our new style.
