asp.net - Property null after postback - Dynamically loaded control -


i'm aware question has been asked many times before suspect have unique scenario.

i'm loading child control (ascx) , setting property on control. works fine until postback property null.

herewith first class loads childcontrol :

protected override void createchildcontrols() {     myusercontrol control = (myusercontrol)page.loadcontrol(_ascxpath);     control.myproperty = base.myproperty     controls.add(control); } 

then, on child control i've got following code:

public partial class myusercontrol : usercontrol {     public mytype myproperty { get; set; }     protected void page_load(object sender, eventargs e)     {         //exception on next line because property null (only on postback)         var somevalue = myproperty.subproperty; 

ok. let me try explain it.
1. once page created, full page lifecycle
2. click on control create user control, , it
3. entering value control, , getting postback
4. on server side postback handled, can see viewstate actions appear page loaded.
1 of main purposes of viewstate handling control events, see if changed, or save states or else.
5. if on moment, when viewstate loaded control still not constructed, it's events , values ignored.

solution either make static control , hide it, either create before viewstate actions started.
