Fix SHIFT+F10 keyboard shortcut for context menu in TextInput by Nitin-100 · Pull Request #15621 · microsoft/react-native-windows

Description

This PR fixes the SHIFT+F10 keyboard shortcut not working to show the context menu in TextInput components. Previously, pressing SHIFT+F10 would cause the application's File menu to blink instead of showing the TextInput context menu.

Type of Change

Bug fix (non-breaking change which fixes an issue)

Why

The SHIFT+F10 keyboard shortcut is a standard Windows accessibility feature for opening context menus. Users expect this shortcut to work in TextInput fields to access cut/copy/paste operations via keyboard.

Root Cause: Windows intercepts SHIFT+F10 at the system level. For ContentIsland hosting, the InputKeyboardSource.ContextMenuKey event wasn't being handled, so the event would fall through and activate the application's menu bar instead.

What

The following changes were made to fix the issue:

Added ContextMenuRoutedEventArgs interface to Composition.Input.idl - New args class with Handled, Position, and IsKeyboardTriggered properties. This follows the same pattern as KeyRoutedEventArgs/CharacterReceivedRoutedEventArgs for easy future extension without breaking API changes.
Added ContextMenu public event to ComponentView.idl - Allows native components to customize context menu behavior by subscribing to this event.
Added OnContextMenu virtual method to ComponentView - Base class method that derived components can override to handle context menu requests.
Added ContextMenuKey event handler in CompositionEventHandler - For ContentIsland hosting, this subscribes to InputKeyboardSource.ContextMenuKey and routes the event to the focused component's OnContextMenu method.
Added WM_CONTEXTMENU handling in CompositionEventHandler::SendMessage - For HWND hosting (CompositionHwndHost), this routes the WM_CONTEXTMENU message to the focused component.
Implemented OnContextMenu in WindowsTextInputComponentView - Calls ShowContextMenu() when the context menu is not hidden via props.

Screenshots

N/A - This is a keyboard interaction fix. Testing requires:

Focus a TextInput component
Press SHIFT+F10
Context menu should appear with Cut/Copy/Paste options

Testing

Manual Testing Performed:

Verified SHIFT+F10 now shows the context menu in TextInput
Verified right-click context menu still works
Verified contextMenuHidden prop still prevents context menu from appearing

Test Scenarios:

TextInput with focus + SHIFT+F10 → Context menu appears
TextInput with contextMenuHidden={true} + SHIFT+F10 → No context menu
Right-click on TextInput → Context menu appears

Changelog

Should this change be included in the release notes: yes

+      args.Handled(true);
+    } else if (msg == WM_RBUTTONUP && windowsTextInputProps().contextMenuHidden) {
+      // Context menu is hidden, just mark as handled
+      args.Handled(true);


Why mark it as handled if contextMenu is disabled? Why not allow apps to add their own right click behaviors?

vnext/Microsoft.ReactNative/Fabric/Composition/TextInput/WindowsTextInputComponentView.cpp


+void WindowsTextInputComponentView::OnContextMenu(
+    const winrt::Microsoft::ReactNative::Composition::Input::ContextMenuRoutedEventArgs &args) noexcept {
+  // Handle context menu event (generated for SHIFT+F10, Context Menu key, or right-click)


If this event is generated on right-click, do we still need the WM_RBUTTONUP handlers? -- Or is this comment incorrect?

acoates-ms · 2026-02-08T00:42:39Z

vnext/Microsoft.ReactNative/ComponentView.idl

    DOC_STRING("Used to handle key up events when this component is focused, or if a child component did not handle the key up")
    event Windows.Foundation.EventHandler<Microsoft.ReactNative.Composition.Input.KeyRoutedEventArgs> KeyUp;
    event Windows.Foundation.EventHandler<Microsoft.ReactNative.Composition.Input.CharacterReceivedRoutedEventArgs> CharacterReceived;
+    DOC_STRING("Used to handle context menu events (SHIFT+F10, Context Menu key, or right-click) when this component is focused")


Given that this event is basically the InputKeyboardSource.ContextMenuKey event, which is a keyboard event. I dont think it would get fired on right-click as the comment here suggests. Also we should call the event ContextMenuKey to be consistent with the event it actually corresponds to.

acoates-ms · 2026-02-08T00:43:57Z

vnext/Microsoft.ReactNative/Composition.Input.idl

+    DOC_STRING("Gets or sets whether the event was handled. Set to true to prevent default behavior.")
+    Boolean Handled { get; set; };
+    DOC_STRING("Gets the position where the context menu was requested, in local coordinates.")
+    Windows.Foundation.Point Position { get; };


A keyboard event wouldn't really have a position associated with it. The upstream InputKeyboardSource.ContextMenuKey has no position associated with it.

vnext/Microsoft.ReactNative/Fabric/Composition/CompositionEventHandler.cpp

      UpdateCursor();
      return 1;
    }
+    case WM_CONTEXTMENU: {


We dont need to maintain the CompositionEventHandler::SendMessage code path any more. That was for driving a react root view without a ContentIsland. But that is no longer a supported scenario.
