What is the last stage to attach viewstate Data to a dynamic control?

I have an Ascx control which I reload every Page_load using Loadcontrol.

This Ascx has a Button And Label

The Label initially contains "aaa".

When I click the button the page reloads and recreates the ascx.

The good thing is that the "aaa" is kept - although it's a new instance of the ascx.

I was wondering to my self why ? and I've answered to myself that's its because the ID of the ASCX which is the same so he 开发者_如何学运维is attaching the viewstate from the last postback to the current instance.

Question

What is the latest page event which I can create the control so that it will be able to attach the viewstate (from the last postback)to the new generated control ?

Following are the events occur during ASP.NET Page Life Cycle:

1)Page_PreInit
2)Page_Init
3)Page_InitComplete
4)Page_PreLoad
5)Page_Load
6)Control Events
7)Page_LoadComplete
8)Page_PreRender
9)SaveViewState
10)Page_Render
11)Page_Unload

Among above events Page_Render is the only event which is raised by page. So we can't write code for this event.
