Announcing Telerik UI for WinUI v0.5.0—the latest WinUI release is live, now fully packed with tons of new components and a brand new sample app.

Today we are adding to the suite: MaskedInput, Map, Expander, DataBars, Sparklines, RadialMenu, EventToCommandBehavior components and CRM application built with Telerik UI for WinUI and Prism Library. 🐱‍👤

Let’s go through all the new stuff in this release.


MaskedInput in a date and time form field separates each piece of data: year, month date, hour, minute, second, time zone.

The first addition to the suite is the MaskedInput control. This is a component that formats and constrains text to a predefined pattern or a pattern you define. It provides input validation and masks, such as date, IP Address, SSN, phone number, digits, currency and decimals.

You can find below all the supported masks as well as some information about each one of them:

  • None: No mask, the control behaves like a regular TextBox.
  • DateTime: Used for handling DateTime user input and returns a DateTime object.
  • FreeFormDateTime: Tries to recognize a free-form string and convert it to a valid DateTime object.
  • TimeSpan: Used for handling TimeSpan user input and returns a TimeSpan object.
  • Numeric: Used for handling numeric user input and returns a decimal value.
  • Standard: Used for handling standard (alphanumeric) user input and returns a string value.
  • Regex: Used for handling and validating a standard user input against a regular expression. Provides errors if regex is not matched and returns a string value.
  • IP: Used for handling and validating an IP address input and returns a string value.
  • Email: Used for handling and validating an email address input and returns a string value.

The control provides numerous customization options that will allow you to achieve any scenario. Make sure to play around with RadMaskedInput in our online WinUI demo application and visit the MaskedInput control documentation.

When working in more advanced development scenarios, we often find ourselves leaning toward the MVVM pattern for producing cleaner, loosely coupled, easier-to-test code. But along with this comes the responsibility of ensuring that all the controls we are using can follow this pattern.

While it is very easy to work with the event-based model that exists across the .NET framework, events do not play well into the mindset of reducing traditional code-behind and instead handling logic within a ViewModel. This is where the Telerik EventToCommandBehavior class comes into use to allow your events to fire and your code to respond accordingly, all in the ViewModel without touching the code-behind of the .xaml files.

For more info, check out the EventToCommandBehavior help article.
