Properties

Cancel

bool Cancel

The host may set this flag to TRUE to cancel the screen capture. If canceled, the screen capture UI is not displayed regardless of the Handled property. On the script side, it will return with a NotAllowedError as Permission denied.

Handled

bool Handled

The host may set this flag to TRUE to prevent the ScreenCaptureStarting event from firing on the CoreWebView2 as well. By default, both the ScreenCaptureStarting event handlers on the CoreWebView2Frame and the CoreWebView2 will be invoked, with the CoreWebView2Frame event handlers invoked first. The host may set this flag to TRUE within the CoreWebView2Frame event handlers to prevent the remaining CoreWebView2 event handlers from being invoked. If the flag is set to FALSE within the CoreWebView2Frame event handlers, downstream handlers can update the Cancel property.

OriginalSourceFrameInfo

readonly CoreWebView2FrameInfo OriginalSourceFrameInfo

The frame info of the frame where the screen capture starting request originated.

Methods
