DesktopWebView2ControlMBS.IsPinchZoomEnabled as Boolean

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	WebView2	MBS WinFrameworks Plugin	21.5	❌ No	✅ Yes	❌ No	❌ No	Desktop only

Enable or disable pitch zoom.

Pinch-zoom, referred to as "Page Scale" zoom, is performed as a post-rendering step, it changes the page scale factor property and scales the surface the web page is rendered onto when user performs a pinch zooming action.

It does not change the layout but rather changes the viewport and clips the web content, the content outside of the viewport isn't visible onscreen and users can't reach this content using mouse.
The IsPinchZoomEnabled property enables or disables the ability of the end user to use a pinching motion on touch input enabled devices to scale the web content in the WebView2. It defaults to TRUE. When set to FALSE, the end user cannot pinch zoom after the next navigation. Disabling/Enabling IsPinchZoomEnabled only affects the end user's ability to use pinch motions and does not change the page scale factor. This API only affects the Page Scale zoom and has no effect on the existing browser zoom properties (IsZoomControlEnabled and ZoomFactor) or other end user mechanisms for zooming.

Needs WebView2 in version 1.0.902.49 or newer.

Communication from the WebView's top level HTML document to the host is allowed via window.chrome.webview's postMessage function and add_WebMessageReceived method (see add_WebMessageReceived documentation for details).
