Forcing a postback

Question

You can manually call the method invoked by PostBack from the Page_Load event:

public void Page_Load(object sender, EventArgs e)
{
    MyPostBackMethod(sender, e);
}

But if you mean if you can have the Page.IsPostBack property set to true without real post back, then the answer is no.

You can use a data-bound control like the Repeater or ListView  re-bind it to a list of control properties as needed  and let it generate the controls dynamically   As an alternative  you can use Response Redirect      to re-load the same page

No  not from code behind  A postback is a request initiated from a page on the client back to itself on the server using the Http POST method  On the server side you can request a redirect but the will be Http GET request
