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 (developer portal, back-end services, reporting/analytics and process)
  • Microsoft Store

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:

  • Windows:
  • Documentation on docs.microsoft.com
    • Sign in to give documentation feedback via Github
  • Visual Studio / .NET

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?

      • 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…

        • 1803 NavigationView built-in back button placement looks terrible.

          For 1803, I like that the backbutton is now built-in to the NavigationView control. However, the placement of the button looks terrible next to the hamburger button.

          I was actually excited to see it was built into the Nav control because i can't figure out where to place the backbutton either such that it doesn;t look weird and out of place... but, the built-in nav backbutton doesn't solve the problem either... it still look weird and extreme beta...

          • 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.

            • Issue with Scroll Bar

              Hello guys,

              I experienced problem with UWP ListView, particularly using ISupportIncrementalLoading interface as a datasource.

              A few words about problem context:
              In our UWP app there is a ListView, and it uses ISupportIncrementalLoading as a DataSource.
              And while next part of data is loading, ListView is disabled.

              So, the problem in that if you scroll ListView in way you catch ScrollBar and pull it to the down,
              when you scroll to the end of the list, ListView will be disabled for some period of time (while data is loading).
              And if you release mouse button from ScrollBar
              while ListView is…

              • RichTextBlock TextHighlighter crashes if used after an InlineUIElement

                Exactly as the title says. Attempting to use TextHighlighter(s) with a StartIndex after an InlineUIElement will result in a crash. I have included code to reproduce the issue:

                C#: https://hastebin.com/owacelasov.cs

                XAML: https://hastebin.com/ujuxacilug.xml

                The issue seems to be somewhere in Windows.UI.Xaml.dll!TextBlockViewHelpers::AdjustPositionByCharacterCount(). It appears that garbage data (from the stack, I assume) is being used for the value `curInlineLength`. Call stack: https://hastebin.com/legulilabu

                  • Support Multiple Functions for x:Bind

                    The following example doesn't show an error in the Designer, but throws errors in the generated code. If I add a (x:Int32) case before the inner function I get a 'Functions cannot have other functions as parameters' error.

                    Width="{x:Bind exf:Bind.Clamp(exf:Bind.Subtract(ContentHolder.(ex:FrameworkElementExtensions.ActualWidth), 30), 100, 300)}"

                    It'd be great if we could chain functions together in x:Bind to create more complex expressions. The above case is trying to subtract from the width of another element, but clamp it within a specific range.

                    Rather than writing a specific function for this purpose, it'd be nice if it could be composed of individual pieces that…

                    • Load PathIcon "data" from svg file added to project

                      Suggestion for Pathicon "DataUri Property" for loading PathIcon from a Svg File, instead of specifying messy vector strings, nobody really wanted to put this stuff ("F1 M 16,12 20,2L 20,16 1,16") in their xaml. Example:

                      <PathIcon
                      DataUri="ms-appx:///Svg/MyButton.svg"
                      HorizontalAlignment="Center"/>

                      Notice: "DataUri Property" and Resource path ms-appx:/// pointing to svg file added to visual studio project under an Svg folder.

                      Another possibility is to allow DataUri to point to a text file holding this type of stuff: "F1 M 16,12 20,2L 20,16 1,16". Example:

                      <PathIcon
                      DataUri="ms-appx:///PathIcons/MyButton.txt"
                      HorizontalAlignment="Center"/>

                      Then, MyButton.txt can contain:

                      "F1 M 16,12 20,2L 20,16 1,16".

                      • Add "Delay" or "KeyTime" property to Setter

                        With Composition Behaviors we have a very nice way to do animations using just setters, however if you want to change Visibility of a control after performing animation you have to add a storyboard to your visual state, otherwise it will be changed immediately.

                        Would be great if setter had "Delay" property to only execute it after a certain amount of time.

                                  • UWP ListView scrolling does not keep up with touchpad/mousewheel scrolling

                                    I made a UWP app with a ListView (using KeepLastItemInView).
                                    On many systems (probably the slower ones), the scrolling behavior is very odd. Using the touchpad/mousewheel, the scrollbar starts moving, but not the contents of the ListView. After a while the contents start moving, but there is no way to move to the very top or very bottom using only the touchpad/mousewheel. I need to drag the scrollbar using the mouse to go the bottom/top of the ListView. This behavior is not consistent. On other systems is works as expected.

                                    • Horizontal Layout for ColorPicker control

                                      The existing color picker have a very long height. Most of the screen a wide, so why not a horizontal layout for ColorPicker.

                                      I know this will be simple, just edit the style, but I can't make it right

                                      • Navigation View should be more consistent. Collapsing back button leads to very ugly look when the view is extended to title bar.

                                        Collapsing back button leads to very ugly look when the view is extended to title bar. Even the hamburger button does not work properly when using extended view and collapsed back button. In minimal mode,
                                        the hamburger button is on the side of the back button. Nav View should be made a full proof solution for developers. Nav View should be more integrated to the application so that the app is consistent.

                                        • Make Textblock support ReadOnlySpan<T> and ReadOnlyMemory<T>

                                          Since we are passing a string via the x:Bind attribute to some UI controls, it would be nice if we could make the binding to a ReadonlySpan<T> so we avoid allocations. This can be very benefitial in datatemplates in Listviews and Gridviews.
