主题: Re: [edk2-discuss] Refresh currently displayed form

Okay, I actually read the rest of your question and your problem is deeper
than that. What you need is for the device to be connected to a driver
(driver which might need to be loaded from the device option ROM), boot
manager to re-enumerate boot options, and then the page can be reloaded.
This is more difficult than what I originally thought you were trying to do.

Cheers,
Tom

Hi,

You can add a 'refreshguid' property to a number of VFR objects. Then,
whenever you signal the event group with that guid, the object should be
refreshed by the HII Browser.

Cheers,

Hi all,

How can I refresh the currently displayed form?

The problem I'm trying to solve is that when on the BootManager page,
insertion or removal of a device does not update the form, leaving the list
of boot options in an invalid state.

Right now I'm trying to hack in an event to accomplish this, but someone
said there may be a mechanism to do this.

Thanks,
Tim
