unable to Maintaining ViewState Across postbacks in a Usercontrol

[Udit]

I am writing a usercontrol that works as a years scheduler.This
usercontrol has some elements created at design time like 2 link
buttons to navigate years.
The calander is created dynamicaly by adding days at runtime using
HtmlControls.HtmlAnchor and i add its Server.Click event also at
runtime.
My problem is that the designtime controls work fine and are able to
maintain viewstate until i click any of the runtime controls which
destroys the entire viewstate and the ServerClick event of the Anchors
also fails to fire.
Any sugessions on this.

Dynamically creating items is always a little bit tricky (well, more
tricky than design-time controls).

In the past when I've wanted to maintain viewstate-type information on
dynamically created controls I've manually added them to the page's
viewstate, and then manually pulled them back out on a postback and
re-applied them to the (now newly) re-created dynamic control.

If there's a better method I hope somebody would post information.. But
otherwise Viewstate.Add is your friend

ohh, and on the part about the ServerClick not firing, make sure that
you have re-created the control (the HtmlAnchor in this case) on the
postback BEFORE you exit the page_load.. otherwise there is no control,
and if there is no control, you can't have a ServerClick event, if that
makes any sense...

Thanx for your reply.
I was able to make it work by creating controls with same id on every
post back and by calling this dynamic controls creation function on the
pageprerender event.
