Getting Started with WinUI MaskedInput

Updated on Mar 26, 2026

In this help article, we are going to create a RadMaskedInput control using the Telerik UI for WinUI.

Assembly References

In order to use the RadMaskedInput controls in your projects, you have to add a reference to the following assembly:

Telerik.WinUI.Controls.dll
Telerik.Licensing.Runtime.dll

Merge the Generic.xaml ResourceDictionary

In order for the masked input controls to receive their styles, you have to merge the Generic.xaml ResourceDictionary in App.xaml.

Example 3: Merge the Generic.xaml ResourceDictionary

XAML

<Application.Resources>
	<ResourceDictionary>
		<ResourceDictionary.MergedDictionaries>
			<XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" />
			<ResourceDictionary Source="ms-appx:///Telerik.WinUI.Controls/Themes/Generic.xaml"/>
			<!-- Other merged dictionaries here -->
		</ResourceDictionary.MergedDictionaries>
		<!-- Other app resources here -->
	</ResourceDictionary>
</Application.Resources>

Adding a RadMaskedInput control to the Project

You can access the RadMaskedInput controls through an alias pointing to the Telerik.UI.Xaml.Controls.Input namespace: xmlns:input="using:Telerik.UI.Xaml.Controls.Input"
