I need to customize the page to present the content of sub page .

How to return the closed status and partial data of the sub page to the main page after it is closed?

`

internal class CefLifeSpanHandler : ILifeSpanHandler
{
    public bool OnBeforePopup(IWebBrowser chromiumWebBrowser, IBrowser browser, IFrame frame, string targetUrl, string targetFrameName, WindowOpenDisposition targetDisposition, bool userGesture, IPopupFeatures popupFeatures, IWindowInfo windowInfo, IBrowserSettings browserSettings, ref bool noJavascriptAccess, out IWebBrowser newBrowser)
    {
        if (!string.IsNullOrEmpty(targetUrl))
        {
            //customize 
            ChromiumWebBrowser browserTemp = chromiumWebBrowser as ChromiumWebBrowser;
            FormNew formNew = new FormNew(browserTemp, targetUrl);
            formNew.Show();
            newBrowser = null;
            return true;
        }
        //other,print...
        newBrowser = null;

You are cancelling creation of the popup, so the parent->child relationship doesn't exist. It's not possible to communicate between the two using your code.
