Universal Windows Platform

Welcome to the Universal Windows Platform Developer Feedback site. This site provides the Windows developer community with a channel for feedback on the following topics:

  • Windows developer platform (APIs, runtimes, and controls)
  • Dev Center (dashboard, reporting/analytics, submission process, etc.)
  • Microsoft Store

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

What this forum is not intended to cover or capture:

  • Windows consumer suggestions: Use the Windows Feedback Hub app built directly into Windows 10
  • Documentation on docs.microsoft.com: Sign in at the bottom of the page to give documentation feedback via Github
  • Visual Studio / .NET: Use the Visual Studio UserVoice site

If you’re new to UserVoice, two things to keep in mind are (a) List items (and item rankings) represent community interest in features, and not the 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 (or if too many different ideas are included in one suggestion).

How can we improve the Windows dev platform?

  1. Modern Windows UI in Win32 desktop applications

    Bring modern Windows UI to existing Win32, WPF and Windows Forms desktop apps with the option to adopt islands of Windows.UI.Composition and Windows.UI.XAML content incrementally. Allows desktop apps to incrementally adopt UI innovations and creates a bridge to UWP for app UI.

    • UWP Grid should have ShowGridLines property from WPF

      The WPF Grid control had a ShowGridLines property. This is helpful for layout debugging. This property is missing in UWP.

      • SwipeControl should support mouse input

        The SwipeControl control should support mouse input as well as touch input. Currently it only supports touch input.

        I appreciate that swipe controls have come out of developments around touch interfaces. However on a platform that allows for a single app to run on both desktop and touch devices I think that users will be expecting to be able to interact with the app in similar ways across devices.

        Microsoft have set precedent for this in their own apps. Outlook for example utilises a SwipeControl type arrangement (that can be interacted with using a mouse) for marking emails as read…

        • TreeView event for child re-ordering

          The UWP TreeView control lacks an event to notify that child nodes have been re-ordered due to a drag and drop. The DragItemsCompleted event is fired but there is no direct information in the arguments about whether the child ordering has changed or whether a child has been added.

          • Add PaneBackground Property to NavigationView

            It is currently possible to change the background brush of the NavigationView itself, but the Pane, in particular, is not so straightforward. Users can modify the designated ResourceKey, but cannot change this brush outside of XAML.

            Users would benefit greatly from a "PaneBackground" property that can be set to an AcrylicBrush, etc. Especially, since the pane of this control is currently opaque by default in a WPF XAML Island.

            To reproduce this situation, please create an "XAML island" in a WPF application. Setting the child to a NavigationView. Then, from C#, search the NavView object for a simple PaneBackground property.…

            • Xamarin.Forms - Prevent keyboard from showing on Entry field focus

              Currently, Entry field in Xamarin.Forms provides no functionality to prevent soft keyboard from showing up entirely. There are solution out there that will hide it but they make things even worse since now you have keyboard popping up briefly, then disappearing from the screen.

              It feels like having a way to disable keyboard from showing up entirely on an Entry field makes sense. For example, I make my own buttons, that resemble keyboard. Tapping on each of these, puts some characters in the Entry field without showing keyboard but only when Entry field receives focus.

              Another example, scanning with external…

                  • MediaTransportControls do not auto-hide correctly

                    MediaTransportControls no longer auto-hide correctly for UWP apps on desktop when using the mouse pointer. When the pointer is used to click the play/pause button, the transport control bar begins to hide and then immediately pops back up again. This bug does not occur with a game controller.

                    This appears to be related to the introduction of MediaTransportControls.ShowAndHideAutomatically property in Build 16299.

                    I am using Windows v1809.

                    This bug is reproducible in any app which uses the transport controls, including the XAML Controls Gallery app (under Media) available in the MS Store. The link to the app can be found…

                      • Open the Windows 10 emoji panel in a TextBox control from code.

                        It is possible to open the emoji panel with keyboard shortcuts (Windows logo + .). It would be nice to be able to open the panel from code as well.

                        • 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.

                          • 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

                                With the announcement and preview release of WinUI Nuget package, we are able to release and update XAML controls independent of OS Updates. We also design controls for backwards compatibility. We’ve listened to customer feedback based on our initial implementation, one being to enable backwards compatibility. Due to this feedback, we are adjusting the implementation to include Input Validation inside the WinUI Nuget Package. We are hopeful to release a backwards compatible version of Input Validation in calendar year 2019.

                                Add an easy to use and customizable Ribbon control like the ones found in the Office Mobile apps, that scales on PCs to Phones. While we can implement it ourselves, it does require a lot of work, and putting it in a XAML control would make life so much easier.

                                • ScrollViewer overpan API

                                  Currently when you overpan a ScrollViewer, where's no way to tell how much negative offset it is unless you do hacks like calculating it every 50ms via a Timer.

                                  This will make interesting actions like 'Pull to Refresh' very hard to implement.

                                  Would be nice to have an event to listen to this with a OverpanOffset property or something.

                                  • Add PanePlacement Top and Bottom to SplitView

                                    Seeing as SplitView is a control used to divide content between and pane and content area, it would make sense for SplitView to allow a PanePlacement.Top and PanePlacement.Bottom in addition to its current Left and Right parameters.

                                    This change would allow Developer to be able to consider the usage of SplitView when targetting small WVGA/WXGA such as the Lumia 520/525/530 which have an extremely thin horizontal resolution compared to its available vertical space.

                                    If this change was made, it would be easier to target a UI to low resolution/low end devices by being able to set the pane to top…

                                    • Allow C# style boolean conversion with x:Bind

                                      With x:Bind we can invert a boolean property with a ValueConverter like this:

                                      Visibility="{x:Bind IsLoading,Converter="{StaticResource BooleanInverseConverter}"

                                      But wouldn't it be much cleaner for that widely used boolean case to write just this:

                                      Visibility="{x:Bind !IsLoading}"

                                      To generated the code should be possible, and also to check in that generation whether IsLoading is a boolean or not. Even without checking, it won't compile if IsLoading wouldn't be a boolean, which is fine.

                                      Thanks,
                                      Thomas

                                      • Can you bring back cppwinrt's xaml programmatic support

                                        Earlier this year (but with cppwinrt still new!) I created a complete complex UI using cppwinrt's programmatic support for xaml: e.g. StackPanel(), Grid(), RowDefinitions, Column Definitions, Children().append(), etc. Quite a lot of work but it easy to read and ran great. Is all of that gone? Or is there still a way to use those cppwinrt features?

                                        • VisualState setters should support custom attached properties

                                          The VisualStateManager ignores Visual State Setters using custom attached properties. This works with normal attached properties, so it's confusing that it doesn't work for custom ones. The hack to get this to work is really ugly and requires custom code for every case using reflection: https://social.msdn.microsoft.com/Forums/expression/en-US/0f9826e1-48d2-4cd7-8253-a5b9aaf0e03d/uwpadaptative-triggers-with-custom-attached-properties-in-windows-10-uwp
