The Page object calls the RaisePostBackEvent method when a postback occurs. This call occurs in the page life cycle after loading and change notification are complete but before prerendering occurs.
The following example uses the RaisePostBackEvent method to notify ASP.NET that a post-back event is raised when a custom userButton server control is clicked.
Sub DisplayUserName(Sender As Object, e As EventArgs) Response.Write("Welcome to " + Server.HtmlEncode(userName.Text)) End Sub Sub MyRaiseEvent(Sender As Object, e As EventArgs) 'Raises a post back event for a control. Me.RaisePostBackEvent(userButton, "") End Sub Sub Page_Load(Sender As Object, e As EventArgs) 'Registers a control as one that requires postback handling Me.RegisterRequiresRaiseEvent(userButton) End Sub
