Yes, post it as an answer. If I happen to visit this page again, I'll vote 5, especially if you explain why this is not an event.

Hi Page.VerifyRenderingInServerForm() is not an event but rather a method. It makes sure that any HtmlForm control is rendered for the specified ASP.NET server control at run time. Controls that are required to be inside <form runat=server> tags can call this method before they render so that an error message is shown if they are placed outside the tags. Controls that post back or depend on registered script blocks should call this method in an override of the Control.Render method. Pages that have a different way of rendering the server form element can override this method to throw an exception under different conditions.

as stated in http://msdn.microsoft.com/en-us/library/system.web.ui.page.verifyrenderinginserverform.aspx[^]

C#

// Override the Render method to ensure that this control
// is nested in an HtmlForm server control, between a <form runat=server>
// opening tag and a </form> closing tag.
protected override void Render(HtmlTextWriter writer) {
    // Ensure that the control is nested in a server form.
    if (Page != null) {
        Page.VerifyRenderingInServerForm(this);
    }
    base.Render(writer);
}
