Question

Suppose that, after a click on a asp:button, I’d like to store the actual “view”, with selected value for each controllers, like asp:checkbox, or input inserted by users on inputbox.

Than, I change page, with a link such as “back to the previous page”. I’d like so “restore” the old actual form, before leaving it.

Is it possible with .NET? Or I need to implements all controls in variables and put them in session?

You don’t need sessions to do this. Just make use of JavaScript.

Consider you have two pages Page1.aspx and Page2.aspx.
You have textboxes , checkboxes , radiobuttons on Page1.aspx and you have a button “Submit”. By clicking the button it takes to Page2.aspx.

Just have a button “Back to Previous Page” on Page2.aspx , which on clicking takes you to Page1.aspx with all those values still being there. To do this, Add this line on your Page2.aspx page_load event

protected void Page_Load(object sender, EventArgs e)
{
 btnBackButton.Attributes.Add("onClick", "javascript:window.history.go(-1);return false;");
}
