In this blog, we’ll look at the major updates in the [WinUI](https://www.syncfusion.com/winui-controls) and [WPF](https://www.syncfusion.com/wpf-controls) platforms. ## WinUI First, let’s see the new updates in the WinUI platform! ### ComboBox #### NoResultFound support The [WinUI ComboBox](https://www.syncfusion.com/winui-controls/combobox) now allows users to display text indicating that there are no search results found. ![Displaying No Results Found text in WinUI ComboBox](https://www.syncfusion.com/blogs/wp-content/uploads/2024/01/Displaying-No-Results-Found-text-in-WinUI-ComboBox.png) Displaying No Results Found text in WinUI ComboBox ### Masked TextBox #### Error type indication You can display an icon to indicate the type of error in the [WinUI Masked TextBox](https://www.syncfusion.com/winui-controls/masked-textbox) control. ![Different error types indication in WinUI Masked TextBox](https://www.syncfusion.com/blogs/wp-content/uploads/2024/01/Different-error-types-indication-in-WinUI-Masked-TextBox.gif) Different error types indication in WinUI Masked TextBox ### Ribbon #### More commands option in the quick access toolbar (QAT) This new feature is a convenient dialog window showcasing all available commands within the [WinUI Ribbon control](https://www.syncfusion.com/winui-controls/ribbon) .

Users can seamlessly explore different symbol categories by simply clicking on the tab headers. ![Stencil header tab layout in WPF Diagram library](https://www.syncfusion.com/blogs/wp-content/uploads/2024/01/Stencil-header-tab-layout-in-WPF-Diagram-library.gif) Stencil header tab layout in WPF Diagram Library #### Activity diagrams Users can create activity diagrams programmatically or interactively using built-in activity diagram symbols. They can also add activity diagram symbols to stencils, which allows them to drag activity diagram shapes onto the canvas to construct activity diagrams. An activity diagram is a type of UML (unified modeling language) diagram that visually represents the flow and sequence of activities within a system or business process. ![Creating activity diagrams using WPF Diagram library](https://www.syncfusion.com/blogs/wp-content/uploads/2024/01/Creating-activity-diagrams-using-WPF-Diagram-library.png) Creating activity diagrams using the WPF Diagram Library #### UML uses case diagrams Users can create UML (unified modeling language) use case diagrams programmatically or interactively using built-in UML use case diagram symbols. They can also add UML use case diagram symbols to stencils, allowing them to drag symbols easily onto the canvas to construct UML use case diagrams. A use case diagram visually represents the interactions between different actors (users or external systems) and a system. ![Creating use case diagrams using the WPF Diagram Library](https://www.syncfusion.com/blogs/wp-content/uploads/2024/01/Creating-use-case-diagrams-using-the-WPF-Diagram-Library-1.png) Creating use case diagrams using the WPF Diagram Library #### State diagrams Users can create UML (unified modeling language) state diagrams programmatically or interactively using built-in UML state diagram symbols. They can also add UML state diagram symbols to stencils, allowing them to drag symbols onto the canvas to construct UML state diagrams. A state diagram, also known as a state machine diagram, models the dynamic behavior of a system by illustrating the various states that an object can be in and the transitions between these states in response to events. ![Creating UML state diagrams using WPF Diagram library](https://www.syncfusion.com/blogs/wp-content/uploads/2024/01/Creating-UML-state-diagrams-using-WPF-Diagram-library-1.png) Creating UML state diagrams using WPF Diagram library ### PDF VIEWER The [WPF PDF Viewer](https://www.syncfusion.com/wpf-controls/pdf-viewer) delivers the following new features. #### Syncing from field-related changes You can manipulate form fields and functions including addition, deletion, and modification in the loaded document, syncing it to the PDF Viewer. #### Document-level security enhancement This feature enhances document-level security by limiting the permissions set within the PDF document when it is opened in the PDF Viewer with the user password. **Note:** With the upcoming 2024 Volume 1 release, we will discontinue support for .NET Framework 4.5, 4.5.1, and 4.6 in WinForms, WPF, and the file-format frameworks. Instead, we will provide support for .NET 4.6.2. ## Conclusion Thanks for reading!
