Every control in .ascx file has a "Enableview_state" attribute, by default, it's ture and don't display. I think you would not modify this except touched it accidently.

But if you have any piece of code for initialing controls for you page, you should put these codes in this block to prevent controls being cleared at every round trip:

if(!IsPostBack)

{

.........Initial your controls..........

}

IsPostBack is a default property of ASP.NET page.

Natively, ASP.NET program and DNN module supports storing view state automatically. So you don't need to worry about view state, just drop the control on the page and  write code for events, it's so weired your DNN module does not store view state. I think you can check your global setting for your DNN application or check whether other third party JS caused this problem.

Hi Iann,

I think I made you got wrong. CTRL+F is a shortcut of the find function in Visula Studio. You know, you can search some strings in 'current document' , in 'entire solution' forexample. I've searched for 'enableview_state="false" ' in my entire solution.Of course only text files. I don't know what is going on in core dll's of DNN..
