In this blog, we will see the new controls and major features included in WinUI and WPF for this release. ## WinUI ### Production-ready controls The following WinUI controls were developed to meet industry standards and are marked as production-ready: - [Date Picker](https://www.syncfusion.com/winui-controls/date-picker) - [Time Picker](https://www.syncfusion.com/winui-controls/time-picker) - [NumberBox](https://www.syncfusion.com/winui-controls/numberbox) - [Slider](https://www.syncfusion.com/winui-controls/slider) - [Range Slider](https://www.syncfusion.com/winui-controls/range-slider) ### ComboBox (new) The [WinUI ComboBox](https://www.syncfusion.com/winui-controls/combobox) control (dropdown list) is a text box component that allows users to type a value or choose an option from a list of predefined options. It has several out-of-the-box features, such as data binding, multiselection, filtering, UI customization, and custom templates. ![WinUI ComboBox control](https://www.syncfusion.com/blogs/wp-content/uploads/2021/10/WinUI-ComboBox-control.png) WinUI ComboBox control #### Editable mode Editable text box to type in and select items from the given data source. #### Searching On typing, the best-matched items will be highlighted for easier selection.

The required selection can easily be specified using the **SelectionMode** property. #### Watermark Display placeholder text inside the control until the user inputs the text. #### Appearance customization Dropdown list items and the ComboBox area can be completely customized with an image or custom controls using templates. ## Segmented Control (new) The [WinUI Segmented control](https://www.syncfusion.com/winui-controls/segmented-control) provides a simple way to choose from a linear set of two or more segments, each of which functions as a mutually exclusive option. ![WinUI Segmented Control](https://www.syncfusion.com/blogs/wp-content/uploads/2021/10/WinUI-Segmented-Control.png) WinUI Segmented Control ### Key features - Customize the segmented background, text color, selection style, and more using the built-in features to fit your application’s theme. - Populate the segment items from a collection of strings and business objects. - Completely customize the segments with a custom UI. ## Calendar ### Change the first day of the week based on culture Previously, the first day of the week was always set to Sunday, irrespective of the culture of the Calendar.
