Windows Community Toolkit - WPF and Windows Forms

This repository contains all controls for WPF and WinForms to simplify and demonstate usage of UWP controls.

For everything else in the Windows Community Toolkit (UWP controls, .NET Standard web services, helpers and more), start here

🚨 Archival Notice - 8/30/2023

With the release of Xaml Islands for Windows App SDK 1.4 this repo is being archived.

All feature/issue/discussion inquires related to XAML Islands should be directed to the WindowsAppSDK repository here.

XAML Islands Notice

The set of WPF and WinForms controls found here are only designed to work with .NET Core 3.1, not .NET 5 and above. These controls are using the XAML Islands Windows 10 APIs included within the Windows 10 OS which won't be improved anymore.

WinUI 3's XAML Islands is the path forward to these .NET apps that want to use .NET 5 and WinUI. WinUI 3's XAML Islands are still in development, and we recommend reviewing the WinUI 3 roadmap to get the latest updates. This repository will be archived once WinUI 3's XAML Islands is released.

In the meantime, we suggest you investigate WinUI 3 Desktop as a solution to access Win32 APIs while using the latest native UX platform. See here for more details.

Controls

Control	Minimum supported OS	Description
WindowsXamlHost	Windows 10, version 1809	Adds built-in or custom UWP controls to the User Interface (UI) of WPF or Windows Forms desktop application.
WebView	Windows 10, version 1803	Uses the Microsoft Edge rendering engine to show web content.
WebViewCompatible	Windows 7	Provides a version of WebView that is compatible with more OS versions. This control uses the Microsoft Edge rendering engine to show web content on Windows 10 version 1803 and later, and the Internet Explorer rendering engine to show web content on earlier versions of Windows 10, Windows 8.x, and Windows 7.
InkCanvas InkToolbar	Windows 10, version 1809	Provide a surface and related toolbars for Windows Ink-based user interaction in your Windows Forms or WPF desktop application.
MediaPlayerElement	Windows 10, version 1809	Embeds a view that streams and renders media content such as video in your Windows Forms or WPF desktop application.
MapControls	Windows 10, version 1809	Enables a symbolic or photorealistic map in your Windows Forms or WPF desktop application.

WebView Notice

New: Try out the pre-release preview of WebView2 for .NET here. 🎉🎉🎉

WebView2 will replace the WebView control in the toolkit, as laid out in the introduction to WebView2 here. This means that we've deprecated the WebView control within the Toolkit and are working with the Edge team to convey all the requirements from the open issues here.

Over the next few months, they'll be processing the open requests to ensure the scenarios folks are using WebView for will be supported with its replacement in the future. You can provide feedback directly to the Edge team here. Thank you for using WebView!

microsoft.toolkit.win32's Issues

UWP content in XAML host control is sometimes not correctly sized

I'm submitting a...

Bug report (I searched for similar issues and did not find one)

Current behavior

I noticed an issue where the XAML content inside a XAML host was not sized correctly after dpi changes. This seems to be a more general issue during rapid changes of the host control size. The following code reproduces the issue:

Create a host control (winforms) with a fixed size and a UWP button:

xamlHost = new WindowsXamlHost();
xamlHost.Width = 200;
xamlHost.Height = 200;

Windows.UI.Xaml.Controls.Button b = new Windows.UI.Xaml.Controls.Button();
b.HorizontalAlignment = Windows.UI.Xaml.HorizontalAlignment.Stretch;
b.Content = "Test";
b.Click += B_Click;
xamlHost.Child = b;

this.Controls.Add(xamlHost);

Now change the size twice in the click handler

private async void B_Click(object sender, Windows.UI.Xaml.RoutedEventArgs e)
{
     xamlHost.Width = 400;
     xamlHost.Width = 200;
}

After clicking the button, the host control will now have the expected width of 200, but the UWP button will be clipped because it has a width of 400. I have tried to debug this issue and the toolkit code seems to correctly change the size of the host control. However, after all the size changes, the root UWP element only sees a single layout pass with the outdated width. Unfortunately, the placement of the UWP content in the XAML host control is not handled by the toolkit code, so I have not a found a way to fix this issue.

Expected behavior

UWP content should be sized according to the host size.

Current behavior

Can't add any of the Microsoft.Toolkit.Forms.* or Microsoft.Toolkit.Wpf.* to a .Net Core 3.0 (alpha right now, but we should be prepared) Windows Forms or Wpf project.

WebView can't run as administrator

I'm submitting a...

Bug report (I searched for similar issues and did not find one)

Current behavior

If you try to your app as adminstrator (elevated), the app will not show, no errors or messages, it just doesn't show.

The reason this became an issue, was that I primarily develop websites, and to debug the local IIS, Visual Studio must run as admin, so I have changed the VS shortcut to require that. Unfornately this Means, that any app launched will also run as admin.

The proplem is that it's impossible to debug, when nothing is shown.

Expected behavior

The app should run (Edge can run as admin). If that isn't possible, I suggest, you check at startup, whether it runs as admin and then throw an exception: "WebView can't run as administrator".

That will save hours of frustrating debugging for many people,

Minimal reproduction of the problem with instructions

Run Visual Studio as admin, now launch an app with WebView.

WebViewControlNewWindowRequestedEventArgs.Uri loses hash/anchor

I'm submitting a...

• Bug report (I searched for similar issues and did not find one)

Current behavior

I have a WebView control in a VSTO (Outlook) custom task pane. It loads a web page that has relevant links for the user's current mail.

These links include a # component that is critical to the path, like https://example.com/site#resource:id - that #resource:id is essential and is used by client side JS at the target site.

I've subscribed to the NewWindowRequested event, but in this WebViewControlNewWindowRequestedEventArgs.Uri the #resource:id has been stripped off.

This would be ok server-side as the hash is not sent, but client side it is a bug.

Expected behavior

If the link in the WebView is <a href="https://example.com/site#resource:id">test</test> then WebViewControlNewWindowRequestedEventArgs.Uri.AbsoluteUri should be https://example.com/site#resource:id.

Minimal reproduction of the problem with instructions

• In Visual Studio 2017 create a VSTO project for Outlook.
• Add a XAML UserControl

<UserControl ...>
    <Grid>
        <Controls:WebView ... NewWindowRequested="wbCtrl_NewWindowRequested"/>
    </Grid>
</UserControl>

• Set the source to a page with <a href="https://example.com/site#resource:id">test</test>
• In wbCtrl_NewWindowRequested use your favourite logging tool or just add a breakpoint to check the contents of WebViewControlNewWindowRequestedEventArgs.Uri.
• Add a wrapper Forms.UserControl with and ElementHost containing the above control as its child
• In the application Startup event use this.CustomTaskPanes.Add(... to add the wrapper control.
• Run the program with Outlook
• Click on the test link in the custom task pane.

Note that most of these steps may be uneccessary if a WebView in a standalone application exhibits the same symptoms, I haven't tested it in other contexts yet.

Does Not Support .NET Core 3

According to the Microsoft Docs here

https://blogs.msdn.microsoft.com/dotnet/2018/12/04/announcing-net-core-3-preview-1-and-open-sourcing-windows-desktop-frameworks/

One of the key advantages of .NET Core 3 for WPF is its support for XAML islands, which is available via the code in this repository.
However, the code in this repository is not compatible with .NET Core 3, so either the docs are wrong, or this is a regression, or this is now a feature request.

Does anyone have any insight into this?

Expected behavior

XAML Islands work on multiple WPF Windows, even if they are running on the same thread. Managing multiple UI Threads is a lot of work, and most of the times, unnecessary.

Minimal reproduction of the problem with instructions

Just create a new WPF project, add the nugets, add the UWP WinMDs and Runtime dlls. Add a simple WindowsXamlHost to the MainWindow and make it's InitialTypeName="Windows.UI.Xaml.Controls.Button". The hook up to the ChildChanged event, like this:

private void WindowsXamlHost_ChildChanged(object sender, EventArgs e)
{
    if (((WindowsXamlHost)sender).Child is Windows.UI.Xaml.Controls.Button button)
    {
        button.Content = "Open new Window";
        button.Click += (s, args) =>
        {
            var mainWindow = new MainWindow();
            mainWindow.Show();
        };
    }
}

It will crash with the aforementioned exception.

XAML Island plus Microsoft Advertising Banner Control System.TypeLoadException: Could not find Windows Runtime type Microsoft.Advertising.WinRT.UI.AdControl

I'm submitting a...

Bug report (I searched for similar issues and did not find one)

Background

Following https://docs.microsoft.com/en-us/windows/communitytoolkit/controls/wpf-winforms/windowsxamlhost I Successfully created a UWP Class Library, created a UserControl (MyUserControl1) on it, just changed the Grid Background to red. Then on the WPF side:
<XamlHost:WindowsXamlHost x:Name="WindowsXamlHost1" InitialTypeName="UWPClassLibrary.MyUserControl1" ChildChanged="WindowsXamlHost1_ChildChanged">

It worked perfectly!!, got Red inside the WindowsXamlHost.

Current behavior

Problem arises when inside the UserControl (UWP Class Library) I Add the AdControl (Microsoft.Advertising.WinRT.UI - Microsoft.Advertising Library).
For that I follow => https://docs.microsoft.com/en-us/windows/uwp/monetize/install-the-microsoft-advertising-libraries

UWP side compiles perfect, (in fact when I follow the same guide on a UWP App I get the Advertisings).

On the WPF Side though it doesnt compile. I get a (Missing Assembly Reference to the Microsoft.Advertising library), I solve that by adding a reference to C:\Users{User}.nuget\packages\microsoft.advertising.xaml\10.1805.7001\SDK\Windows Kits\10\ExtensionSDKs\Microsoft.Advertising.Xaml\10.0\References\CommonConfiguration\neutral\ Microsoft.Advertising.winmd

Now WPF compiles, but throw a runtime error => System.TypeLoadException: Could not find Windows Runtime type Microsoft.Advertising.WinRT.UI.AdControl

Expected behavior

Advertising showing in a WPF project thanks to XAML Islands

• Bug report (I searched for similar issues and did not find one)

Current behavior

Create a VSTO (office addon) that uses the Windows-toolkit\WebView and host it inside Outlook. Add a context menu to this addon and attach it to the webview.

• 32bit Outlook hosting the addon. WebView will display the context menu on right mouse click.
• 64bit Outlook hosting the addon. WebView will NOT display the context menu on right mouse click

Expected behavior

Context menu should open the same for both 32bit & 64bit platforms.

Minimal reproduction of the problem with instructions

Sample code to reproduce this issue can be found here: https://github.com/shankslouis/64bitWebviewContextMenuIssue

Steps to repro:

1. Download and run the sample provided on a PC running 64bit Office\Outlook.
2. To see it in action click on New Email message
3. Click on the button FormRegion1

In this screenshot you will see the webpage detected the right click but the context menu did not open when using 64bit Outlook. (It does open when using the 32bit version of Outlook)

To trigger the context menu without right clicking the mouse click the following button

Regressions when using winforms XAML host in 19H1 insider builds

I'm submitting a...

Bug report (I searched for similar issues and did not find one)

Current behavior

Compared to Windows 10 1809, the recent insider builds show a number of regressions when using the winforms XAML host and I am not sure if these are Windows bugs or if the host control code has to be adapted:

• Every keystroke results in two characters in text boxes Fixed
• At least two host controls have to be created to render any UWP controls Fixed
• After DPI changes, only the backgrounds of the UWP controls are rendered and no interaction is possible Fixed
• FocusManager.GetFocusedElement() always returns null, even if a UWP control is focused Breaking change. Use GetFocusedElement(XamlRoot)
• Changing focus to the next element in a UWP usercontrol with the tab key is not possible

Expected behavior

No regressions

WebView does not work in the following cases

Please note when migrating an implementation from WebBrowser that the API has changed significantly. The web view provided for Windows Forms and WPF is a subset of the UWP WebView functionality, which may not have the functionality of WebBrowser or may have similar functionality (but under a different API).

This list contains issue specific to the Win32 WebView provided for Windows Forms and WPF.

• Unable to use WebVR. (#2208) Win32WebView does not currently support WebVR. Meanwhile, if you need WebVR you can use either UWP WinJS/PWA or WebView (out of process).
• Unable to play protected media (e.g. Netflix, Spotify). Storage for protected content could not be allocated. App crash.
• Unable to show UI from web pages.
  • JavaScript errors
  • Read HTTP credentials from Windows Credential Manager
  • Show JavaScript popups (e.g. alert). For a workaround see https://docs.microsoft.com/en-us/uwp/api/windows.ui.xaml.controls.webview#use-of-alert
• High-DPI / Scaling.
  • #2210 Hit targets are off. Fixed in Insider 17681.
  • #2076 WPF WebView does not fill 100% of area. Fixed in 4.0 via #2496
• Cannot access DOM.
  • Use workaround

WebView.NavigationCompleted += (o, e) => {
  string html = WebView.InvokeScript("eval", "document.documentElement.outerHTML");
  …
};

WebView.NavigationCompleted += (o, e) => {
 string script = "document.body.style.background = '#FF00FF';";
 WebView.InvokeScriptAsync("eval", script);

WebView: Gaps from HtmlControl

When porting RSS Bandit to use the WinForms web view, I noticed the following gaps:

• No ability to control image download
• No ability to prevent video download/playback
• No ability to control background audio
• No ability to get into the DOM. Goal here is to get the equiv of IHTMLDocument2/IHTMLDocument3 to get the body and do things like scroll to it, etc.
• Clear method is missing
• No RTL support (setting RightToLeft throws)
• No ability to get the raw html
• No command state change (forward/back)
• In navigation events, no IsRootPage, which is useful for embedded scenarios
• No web progress changed, so no ability to show progress
• No status text changed event
• No document title changed event
• No ability to detect/control iframes
• No ability to handle accelerators for keyboard integration scenarios
• No ability to detect a ctrl+click navigation so we can open a new tab and browse to the url there

Please see this PR for more context and use:
RssBandit/RssBandit#1748

Ideally I'd like to use WebView for RSS Bandit, but there's too much missing still. Look at how much I had to comment-out and disable.

Windows Forms XAML Host: Arrow buttons change focus instead of allowing interaction with the UWP control

I'm submitting a...

Bug report (I searched for similar issues and did not find one) -->

Current behavior

Pressing an arrow key on the keyboard moves the focus to the next element instead of interacting with the currently focused control. This can be reproduced by adding a slider to the XAML host element. Pressing an arrow key should change its value instead of focusing the next element. Interestingly, when packaging the app with a visual studio packaging project (desktop bridge), not only does the focus indicator change (to a solid line instead of a dashed line), but this issue also disappears.

Expected behavior

I would expect the same behavior when the app is started with the .exe file as when it is packaged as a desktop bridge app.

Minimal reproduction of the problem with instructions

• Add a XAML host element containing a slider control
• Changing the value with the arrow keys does not work
• Add a packaging project
• If the app is installed as a package, the focus indicator changes and the slider can be modified

Win32WebViewHost replaces application's Audio Session ownership

I'm submitting a...

• Bug report (I searched for similar issues and did not find one)

Current behavior

System sound mixer shows Win32WebViewHost process as the owner instead of the application containing the WebView control. IAudioSessionEnumerator.

It also affects WebNotifications, because clicking on the notification, it will open an empty window with title "Win32WebViewHost" instead of focusing the application containing that webview.

Expected behavior

Application's process listed in IAusioSessionEnumerator, i.e. in the system's audio mixer dialog window instead of Win32WebViewHost.

Also WebNotification showing the proper application's name as well the callback to bring the application to the foreground.

Minimal reproduction of the problem with instructions

Navigate to any website that emits sound, YouTube, etc.
Open the Volume Mixer (right click the volume icon in systray -> select Volume Mixer).
There will be listed Win32WebViewHost instead of our application name, if more than one application, using WebView, there will be listed as many as applications using webview + sound are running.

And about web notification callback action:
Navigate to Google Play Music webapp. Turn in settings the web notifications and refresh, accept the permission request. It will show the notification. Click the notification. It will open a windows titled Win32WebViewHost and will close after a second or less.
