Hi again.

I have a page which contains several controls with some initial settings established. The user can modify those options by choosing others. I would like to know, If I insert a button control to restore the initial settings, can I employ the LoadViewState method to achieve these?

Thanks in advance for any help.

The viewstate is kind of like a snapshot of the state of the controls. It is created each time the page is rendered and lives are part of the form that is drawn onto the page in the HTML. It can't really be used to "restore" a form to its original state. Each time you change or set a property of a control that is on the web form, you affect the viewstate. The viewstate can't be restored due to the stateless nature of the web (which is of course the whole purpose behind viewstate).

If you want to reload a particular page to its original state, all you really need to do is force a clean request to that page. This could be achieved with a hyperlink that goes to that same page, or by some other means of refreshing, except for a standard postback.

Thanks for your answer. What about the methods Page.LoadPageStateFromPersistenceMedium and Page.SaveStateToPersistenceMedium?
Can I use this methods to achieve this?

I doubt that will help, as that is still viewstate.

You'll need to do as I suggested above, or somehow manually save the state of the page/controls so you can retrieve then later. I don't imagine this would be that easy because of the multitude of control attributes.
