Question

I have a window that opens a pop up and what i want is open the popup as child window or window on top of another and disable the back window? so that somebody cannot go back and close the Main window.

I tried putting the window top most but still i am able to close the main window.

private void axWebBrowser1_NewWindow3(object sender, DWebBrowserEvents2_NewWindow2Event e)
{
    BrowserWindow window = new BrowserWindow();
    window.axWebBrowser1.RegisterAsBrowser = true;
    window.Visibility = Visibility.Visible;
    window.textBox.IsEnabled = false;
    window.Height = 550;
    window.Width = 600;
    e.ppDisp = window.axWebBrowser1.Application;
    window.Topmost = true;            
}

Answer 1

Does setting the owner of the child window help?

private void axWebBrowser1_NewWindow3(object sender, DWebBrowserEvents2_NewWindow2Event e)
{
    BrowserWindow window = new BrowserWindow();
    window.Owner = this;
    ...          
}
