New Picker Controls, Blazor Bindings, Demo Apps and More in R2 2020 for Telerik UI for Xamarin

Try our new picker controls, tinker with Blazor bindings, implement sticky group headers and more with the latest controls and new features for Telerik UI for Xamarin!

R2 2020 is finally here and we have a lot of goodies in store for you! Remember our picker controls fromlast release? ListPicker, TemplatedPicker and DateTimePicker? With this release we have shipped the official versions of these pickers. While working on them during R1 2020, we started some parallel work for creating three more pickers for the stack, namely DatePicker, TimePicker and TimeSpanPicker. 

It is important to point out that we've managed to refactor the internal structure of the existing pickers in a way that all the valuable features will be automatically inherited by the newly provided picker controls, including: 

• Templating 
• Styling API
• Formatting 
• UI virtualization 
• Localization 
• Ranges 
• Commands 

All these features are shared across all pickers, so you can expect the new controls to support them as well.  

DatePicker

The DatePicker control allows the end user to select a date within predefined range. The SpinnerFormat property is used to control which spinners will be visualized visualized and allows for defining  standard and custom format strings for the DateTime object. 

TimePicker

The TimePicker control is designed to enable the selection of time within the range of a single day. It supports both 12- and 24-hour formats. To hold the current selection, the control uses a nullable TimeSpan object.

The SpinnerFormat property is available here as well - define  standard and some of the custom format strings for TimeSpan class to visualize the respective spinners. If the scenario requires setting additional steps for the spinners, the TimePicker component exposes the HourStep , MinuteStep , SecondStep properties. This feature can help when choosing between predefined slots of time.

TimeSpanPicker

The TimeSpanPicker is designed to cover all application scenarios that require selection with longer than 24 hours duration. It also uses a nullable TimeSpan object and allows for the selection of a range with a duration of several days. As the other time related picker, this one also allows setting separate steps to any of the spinners. 

The earlier mentioned refactoring led to slight changes in the public API of the existing DateTimePicker. Everything you need to know about the changes is in our documentation . However, when we compared the advantages and disadvantages of these changes we decided to go ahead and implement them for the better.

On top of the newly provided picker components, we continue to fine-tune and extend the existing ones with fixes and powerful new features. Some of the notable mentions include the ability to customize the headers of the separate spinners.
