in my page,an iframe named "cframe" in a parent iframe named "pframe".
pframe postmessage fired the OnFrameWebMsgRec event.
but the cframe didn't;

Code: Select all

WVBrowser1FrameCreated
....
var
  TempArgs: TCoreWebView2FrameCreatedEventArgs;
  TempFrame: TCoreWebView2Frame;
begin
  TempArgs := TCoreWebView2FrameCreatedEventArgs.Create(aArgs);
  Inc(FFrameIndex);
  TempFrame := TCoreWebView2Frame.Create(TempArgs.Frame, FFrameIndex);
  try
    TempFrame.AddAllBrowserEvents(WVBrowser1);
    Fframes.Add(FFrameIndex, TempFrame);
  finally
    TempArgs.Free;
  end;
  

by above code ,the cframe's FrameIndex is 1,the pframe's FrameIndex is 2.

Hi,

That's unexpected. If that event works for the parent frame it should also work for the child frame.
This might be an issue in the WebView2 framework.

Please, report this issue in the WebView2Feedback repository :
