I suggest you ...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

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. Using C# expressions in WPF bindings

    Consider that my ViewModel has the IsBusy propery. It was great if I was able to do binding like this:

    <ProgressBar Visiblity="{Binding IsBusy}" ... />
    <Button Visiblity="{Binding !IsBusy}" .../>

    Note that I've bound Button's visibility to !IsBusy (Not Busy).

    I used to have this on JavaScript MVVM frameworks like knockout.

    The expression could be more complex like:

    <Button Text="IsBusy && !HasError ? true : false"/>

    Currently I should use ValueConverters for this which is hard to create, for each type of binding required.

    • Make BringIntoView work correctly with UI virtualization

      BringIntoView does not work correctly with user interfaces that are virtualized. A great example is the TreeView. Calling BringIntoView on an item that is not currently on screen will not bring the item into view because it hasn't been drawn yet even though its model exists. The only way to get around this today is through hacks such as : http://lucisferre.net/2010/04/21/virtualizing-stack-panel-wpf-part-duex/

      and

        • include DockingManager, Windows selector and most of the VStudio goodies in standard WPF feature set

          Share some of excellent VS 2010 UI blocks (Docking manager, Windowss selector maybe Architecture Explorer like a graphing helper)
          thus saving time for good people for more high-level tasks and stop overflow of VS-imitating low-quality 3rd party libraries

          • Auto-generate ViewModel interface from {Binding} expressions

            Have the XAML designer automatically generate an interface for the ViewModel based on the Binding expressions in the XAML. This would give the MVVM pattern better type-safety and eliminate data binding errors.

            • Make the DataGrid at least as fast as the WinForms DataGridView

              The WPF DataGrid is useseless for showing more than 1-2K rows. It is either slow and jumpy when virtualizing or eats gigabytes of RAM when not virtualizing.

              Meanwhile the WinForms DataGridView displays upwards of 100K rows without breaking a sweat...

              • Make the WPF Ribbon look closer to the Windows Ribbon

                The current WPF ribbon is not too realistic... The application button is not the right color, nor is the ribbon tab the right gradient. There are some necessary animations not done, while there are animations not found in the Windows Ribbon. The buttons in the ribbon control group do not look similar to the Windows Ribbon buttons at all. I suggest that the WPF Ribbon be made more realistic before any additional development is done.

                  • Native support for video capture and video streaming.

                    It would be nice to have the ability to support a Video capture device natively. Currently you have to jump through a lot of hoops to get this running via DirectShow interop or MediaPlayer ActiveX. I'm thinking of applications like Media players, PVR/DVR functionality, broadcast, etc that can be manipulated in WPF 3D and transforms.

                    • Validation with DataAnnotations like in ASP.NET MVC.

                      Also make Entity-Framework fully compatible and integrated with DataAnnotations validation.

                      • Better custom chrome support for Window

                        It's without a doubt that custom chrome apps are becoming popular, with office as being a leader, and other MS apps.

                        It would be great if full support was baked into the window, I am speaking in terms of:

                        - Better drop shadow support for borderless windows
                        - Retaining animation for minimizing, maximizing windows
                        - Aero snap support
                        - Fixing issues when WindowStyle is none and maximizing causing it to be in Kiosk mode.
                        - Inherent and native support for extending glass into non client area.

                        There are far too much hacking, pinvoking to be done just to achieve these…

                        • iOS and OSX support

                          We're fighting a loosing battle when trying to port applications to iOS and OSX. How about helping some ppl out there that are already trying to allow cross platform support (Xamarin?). Even if it's just silverlight. I'm not sure if this is just a restriction from Apple's side... but it makes it very difficult to build consumer based applications in WPF when many of our customers are running apple products. Telling them to install windows as a virtual machine also doesn't make things that much easier (and cannot be done on iOS).

                          • VideoRendererElement for integration of DirectShow and Media Foundation

                            The VideoRendererElement could provide a renderer filter (DirectShow) or a media sink (MF) or an activation object (IMFActivate). You could use that in your DirectShow filter graph or MF topology.
                            At the moment, the possibilities for using DirectShow/MF in a WPF application are dissatisfying: you can use a native window for video rendering (with all the airspace issues), you can use the combination of an EVR custom presenter and a D3DImage (it is awkward and uses the UI thread for updating the video image), and of course you can use MediaElement with all its limitations (video playback only).
                            We badly…

                            • Add multi-selection support in ListCollectionView (and friends)

                              A ListCollectionView keeps a "SelectedItem" to track selected item in a collection, it would be really nice to extend it so it also has a "SelectedItems"-observablecollection that tracks more than one 1 item. And of course keep "SelectedItem" for the "most selected item" kind of.

                              • Smoother Animations

                                Even running on a powerful computer without transparency and framerate set high, animations are stil a bit choppy.

                                This might be to the fact that there is no VSync, anyways smoother animations would be great

                                    • UI Virtualization with smooth scrolling

                                      It would be great to have improved UI virtualization in listbox's itemscontrol, etc and have smooth scrolling enabled, rather than content scrolling.

                                      • Multithreaded Panels

                                        Sometimes you want a part of the UI to update seamlessly in parallell to what the rest of the UI thread is doing. The only way to achieve this right now is to have a topmost window running on a different thread.

                                        It would be great if there was a Panel Control that could run in a separate thread instead

                                        • Take all the MVVM projects from the WPF Disciples and merge them to create a best of breed framework

                                          The WPF Disciples have many members that are all working on different, but similar MVVM framework projects. Each has some slightly different implementations from each other, but joined together they would be the ultimate MVVM framework.

                                          It would be great to so MS take this community output and provide it to the VS development community at large.. That is if the Disciples grant MS permission to do this.
