Hi all,

In the Telerik UI for .NET MAUI 14.0.0 release, the RadSegmentedControl was rebuilt from the ground up. The control keeps its name and core purpose—display a list of horizontally aligned, mutually exclusive options—but exposes a new API surface, extended styling options, and additional features such as full data binding, selection modes, item templates, size modes, and per-segment commands.

FontSize can be applied trough the ItemViewStyle property of the segmented control. The target type is RadSegmentedControlItemView:

<Style x:Key="SegmentItemView" TargetType="telerik:RadSegmentedControlItemView">
    <Setter Property="FontSize" Value="16" />
</Style>

<telerik:RadSegmentedControl x:Name="segmentControl"
                             ItemViewStyle="{StaticResource SegmentItemView}" />

Regards,
Didi
