How to set Xamarin.Forms Label Font Bold

In Xamarin.Forms I am using a Label and trying to set a Font.

The following code works:-

Label label1 = new Label();
label1.Font = Font.SystemFontOfSize(10);

However trying to specify the Font Attributes such like:-

Label label1 = new Label();
label1.Font = Font.SystemFontOfSize(10, FontAttributes.Bold);

is preventing the ContentPage from rendering with an exception.

There is a Font.BoldSystemFontOfSize(), which could be used, however this is meant to be deprecated, so I am trying to now use Font.SystemOfSize instead.

How is it done using this?

You can set the below in you global view.

<setter property="FontAttributes Value="Bold">

I had a similar situation where the FontAttributes="Bold" of a Label inside a DataTemplate for a ListView were not rendered as Bold in iOS. Android rendered fine.

When not within a DataTemplate, the Bold Label rendered correctly.

The cause was that the default font did not have a Bold available on iOS. When I added a Font="Arial" to the Label, it correctly rendered the Bold in iOS.

I'm sharing this in case someone else has this same issue.

If you need more than one place where the bold font is required then you will be better of creating a style. Either globally in the app.cs with or without a key or in the page level. You can set all the properties you want to the appropriate values and use wherever you want.

I guess I'm late for answering. But still I'd like to mention that, this can be done using XAML now. The following XAML will give the desired output.

<Label Text="Hello Label" FontSize="20" FontAttributes="Bold"/>

You can refer to the following link to more about working with Fonts in Xamarin.Forms.

Here's a piece of code that works in my project:

new Label {
   Text = "text goes here",
   Font = Font.SystemFontOfSize (NamedSize.Medium)
              .WithAttributes (FontAttributes.Bold),
}

This allows you to not specify a certain font size and instead use the font size used by default for the label

Following documentation Xamarin.Forms - Working with Fonts, you should use following code:

Label label1 = Font.SystemFontOfSize (10, FontAttributes.Bold | FontAttributes.Italic)

Same page states that BoldSystemFontOfSize is deprecated.
