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?

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

  1. 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

    • 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…

          • 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…

            • 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.

              • 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…

                      • 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.…

                        • Outlined TextBlock

                          We can easily create an outlined text in WPF.
                          https://docs.microsoft.com/en-us/dotnet/framework/wpf/advanced/how-to-create-outlined-text
                          In UWP, I only found a way with Win2D, but it will draw like a picture, the layout arranges will not work (such as TextWrapping).

                            UWP's Gridview has only Single/Extended/Multiple selection methods. There is no selection method by mouse rectangle selection, like we select in windows explorer. i.e. click-drag to draw a rectangle to select multiple GridView items, using mouse.

                                • ListBox feature to only display complete lines

                                  Default behavior of the Windows.UI.Xaml.Controls.ListBox is to display a portion of the text in the last or first lines which do not entirely fit in the listbox. This forces users to scroll up and down to see all of the text.

                                  The calculation to limit the rows in a listbox to only lines that can be shown is simply ListBox.ActualHeight/TextBlock.ActualHeight. I recommend a property such as "VerticalAlignment" with an enum that includes None, FitWholeLines, Shrink, Grow, whatever.

                                  • 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.

                                      • 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 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
