Does the WPF WebBrowser Control Implement Commands?

Question

I have been trying to use Commands with the WPF WebBrowser control (with DesignMode = "on" ):

Xaml (oversimplified):

<Window>
    <Grid>
       <Button Command="ToggleBold"/>
       <WebBrowser />
    </Grid>
</Window>

...but despite the WebBrowser accepting keystrokes when I type (and formatting a word as bold when I hit Ctrl+B ) nothing happens when I click the button. This indicates to me that the WebBrowser does not natively implement Commands like a RichTextBox .

Can anyone please confirm this?

Answer 1

I can confirm that, WPF WebBrowser control doesn't support WPF commands out-of-the-box. You'd need to implement a layer which handles WPF commands and translates them to the corresponding IHTMLDocument2::execCommand commands. To do that, you could create a custon control (derived from UserControl ) and embed the WebBrowser control inside it. You cannot derive from WebBrowser directly as it's sealed .

我不是WPF专家，但是我知道Webbrowser控件与应用程序中的真实浏览器相同，因此它仅呈现HTML，并且无法理解WPF或asp.net代码。
