Properties
Handled
bool Handled
Indicates whether the CoreWebView2.NewWindowRequested event is handled by host.
If this is false and no CoreWebView2NewWindowRequestedEventArgs.NewWindow is set, the WebView opens a popup window and it returns as opened WindowProxy. If set to true and no CoreWebView2NewWindowRequestedEventArgs.NewWindow is set for window.open(), the opened WindowProxy is for a dummy window object and no window loads. The default value is false.
IsUserInitiated
readonly bool IsUserInitiated
true when the new window request was initiated through a user gesture such as selecting an anchor tag with target.
The Microsoft Edge popup blocker is disabled for WebView so the app is able to use this flag to block non-user initiated popups.
Name
readonly string Name
Gets the name of the new window.
This window can be created via window.open(url, windowName), where the windowName parameter corresponds to Name property.
If no windowName is passed to window.open, then the Name property will be set to an empty string. Additionally, if window is opened through other means, such as <a target="windowName"> or <iframe name="windowName">, then the Name property will be set accordingly. In the case of target=_blank, the Name property will be an empty string.
Opening a window via Ctrl+clicking a link would result in the Name property being set to an empty string.
NewWindow
CoreWebView2 NewWindow
Gets the new window or sets a WebView as a result of the new window requested. Provides a WebView as the target for a window.open() from inside the requesting WebView. If this is set, the top-level window returns as the opened WindowProxy. If this is not set, then CoreWebView2NewWindowRequestedEventArgs.Handled is checked to determine behavior for the CoreWebView2.NewWindowRequested. WebView provided in the NewWindow property must be on the same CoreWebView2Environment as the opener WebView and cannot be navigated. Changes to settings should be made before setting NewWindow to ensure that those settings take effect for the newly setup WebView.
Uri
readonly string Uri
Gets the target uri of the new window request.
WindowFeatures
readonly CoreWebView2WindowFeatures WindowFeatures
Gets the window features specified by the window.open() call. These features should be considered for positioning and sizing of new WebView windows.
Methods
GetDeferral
Deferral GetDeferral()
Gets a Deferral object and put the event into a deferred state. Use this to Complete the window open request at a later time. While this event is deferred the opener window returns a WindowProxy to an un-navigated window, which navigates when the deferral is complete.
