Universal Windows Platform

Welcome to the Windows Platform Developer (WPDev) Feedback site. This feedback forum provides the WPDev community with a channel for feedback on the following topics:

  • Windows developer platform (APIs, runtimes, and controls)
  • Dev Center Store (developer portal, back-end services, reporting/analytics and process)
  • Windows Stores (Windows and Windows Phone)

Your suggestions will be reviewed by the Windows platform developer team, providing feedback to help with planning ideas and to better understand how developers are using the development platform.

What this forum is not intended to cover or capture:

If you’re new to this whole UserVoice thing, we’d like to note two important things about this site: (a) List items (and item rankings) represent community interest in features, and does not represent an actual priority list for the product team; and (b) Suggestions made using this forum will be moderated if they do not actually represent a feature request.

How can we improve the Windows dev platform?

      • Classic Main Menu

        When building line-of-business-apps for enterprises, we often focus on desktop only. Today we're using WPF for these tasks. But if we want to use UWP for it, we would need a classic menu like we have it in Visual Studio and serveral other "expert applications" (=app with a lot of functionality) that require more than just a hamburger menu or some flyouts

          • We need a classic TabControl for Desktop applications

            For a classic desktop application, we need a TabControl. Currently you can use the Pivot or there are 3rd-party vendors providing a TabControl. But as this is such a central control, it should be part of the platform.
            If you build it, it would be great if you could add configurable close-functionality to the tab-header that is bindable to a ViewModel.

            I’ve spent some hours to build a small MVVM/UWP/Pivot Prototype that does the typical stuff we do today in WPF with TabControl. And I was impressed how far I got. Sample is here:
            https://github.com/thomasclaudiushuber/Uwp-Tab-Control-Spike

            Big asks are asks are …

            • Add a Toolbar to UWP

              In UWP we have a CommandBar, but it seems it's not easy to use to build a classic toolbar for a desktop application. A toolbar stacks items from left-to-right, and it would be great to have such a toolbar in UWP like we have it today in WPF and several other desktop programming models

                • Put a HierarchicalDataTemplate into the Platform

                  You're building on a TreeView-control, as your backlog on https://developer.microsoft.com/en-us/windows/platform shows. I'm using the TreeView of your official samples on https://github.com/Microsoft/Windows-universal-samples/tree/dev/Samples/XamlTreeView. The point that I really miss when working with hierarchical data is the HierarchicalDataTemplate like we have it today in WPF. So I suggest that you bring the HierarchicalDataTemplate to UWP. It makes especially sense when you release a control for hierarchical data like the TreeView.

                  • Add CornerRadius property to Button

                    It would be nice to be able to easily create rounded or circular buttons in UWP without creating custom control template.

                    Reveal effect introduced in Fluent Design should also work.

                    • ExpressionAnimation should support resting points that can invoke keyframe animations

                      Add ability to conditionally trigger a keyframe animation from an expression animation in order to support more complex animation scenarios. See GitHub issue for more information and scenarios (https://github.com/Microsoft/WindowsUIDevLabs/issues/239)

                      • Add Shadows option to UI Elements on XAML

                        Add shadow option to XAML UI Elements.
                        Example usage: <Image Source="ImageLocation.png" Shadow="5,5,5,5"/>
                        Each number represents the shadow in each side.

                        Why? One of basic fluent guidelines are shadows, so it should be easier to devs use it, without the need of 3rd party toolkit or calling the Composition directly.

                            • Tab control like in Microsoft Edge

                              It can happen that sometimes we do need a control to store a list of pages/elements that looks like a Pivot control but with a infinite list of pages/elements. So, I think the tab (header) control of Microsoft Edge can be reused with :

                              * A list of elements (with an icon/title/close button)
                              * A possible template for previewing element (like a small window)
                              * A plus button to add more elements
                              * And maybe other buttons

                                • Need a DirectManipulationCompleting event for ScrollViewer

                                  The DirectManipulationCompleted event of the ScrollViewer fires too late - it only gets called when the animation of the scrolling finishes.

                                  What would be really helpful is to provide an event (maybe something like DirectManipulationCompleting) that would fire as soon as the pointer is released (e.g. finger lifts up from screen).

                                  Original request is from this link -

                                  • UWP XAML should be backwards compatible with older Windows 10 Versions

                                    Currently it is really painful to add new Controls from newer Windows SDK versions to apps and still support older versions.

                                    There needs to be a way to define new XAML Controls/Properties/Etc., as currently if you want to add these, with a lower Minimum version, it has to be from code-behind.

                                    Ways this could potentially be fixed:
                                    Have a separate Class Library that only supports new SDK versions, and it will only be loaded into the app on newer SDK versions, therefore you can write safe XAML markup including new Controls and Properties.

                                    Like how Xamarin.Forms does it, instead of…

                                      Thanks for the feedback William! With the fall Creators update we are introducing conditional runtime statements in markup. This will be backwards compatible to the Creators update and later (min version 15063).

                                      You can append a conditional statement to your namespace with the following syntax:
                                      xmlns:Creators=“using:foo?IsApiContractPresent(Windows.Foundation.UniversalApiContract,4)”

                                      Objects and properties marked with the ‘Creators’ namespace will only be parsed if the conditional statement is true.

                                      Sample markup to conditionally show text:
                                      xmlns:Creators=“http://schemas.microsoft.com/winfx/2006/xaml/presentation?IsApiContractPresent(Windows.Foundation.UniversalApiContract,4)”/>;
                                      < Button Background=“Green” Creators:Content=“Show text if on creators”/>

                                      We’re in the process of adding documentation, samples and tooling for the feature. You can live on the bleeding edge and use it now – be aware that there might be some rough edges in tooling :).

                                      To write adapative code that works on versions before the Creators Update, you’ll need to use on the methods outlined here: https://docs.microsoft.com/en-us/windows/uwp/debug-test-perf/version-adaptive-code

                                    • fluent design backward compatible

                                      There are a lot of upcoming features to help with Fluent design and they are really great, however to make full use of these the features/xaml/controls need to be backward compatible or do a fallback so that apps that do not target only the latest can also use this. This is really a must for apps that target businesses or wish/must to support older devices that will not get the latest versions. (See mobile!)

                                      • Slider should have a 'TickOffset' Property

                                        It'd be great if the Slider control could have a TickOffset property to make the tick marks not start at the left-most edge of the control.

                                        For instance, if I have a slider using doubles with a range of [0.5, 3.0] with a TickFrequency of 1, then I see tick marks at 0.5, 1.5, and 2.5. However, I really want them at 1.0, 2.0, 3.0.

                                        The TickOffset would move the initial tickmark by that amount, so in the above case, I'd set it to "0.5" to move the first tick mark from the start of 0.5 to 1.0.
