EnableViewState Question in nested user controls - ASP.NET

Question

I have a page with (EnableViewState = "true") that has a parent control with (EnableViewState = "true"). The parent control loads a child control.

In the child control, I have a viewstate object that gets assigned to null on postbacks. The strange thing is if I set EnableViewState = "true" on the child control, then everything works fine.

My understanding was this directive is true by default. How does it matter whether I set this explicitly or not.

Answer 1

Is ViewState turned off in the web.config?

Answer 2

If you use LoadControl() to load the controls, asp.net don't know how to restore those controls on postback. If you however make sure all controls are loaded in Page_Init, then the view state will be loaded into the controls.

This control does some of these things for you
