Why is it advisable to store viewstate values ​​in a PreRender event call?

Question

I'm trying to save member variables by storing them in ViewState (only a few small variables), but I read, and I'm going to better save them in ViewState at the PreRender stage than on the Load page?

I see that the ViewState can be saved at any time before rendering the page, but does it matter in PreRender or PageLoad?

No, there is no difference. You just need to save the variables in the ViewState after you change them. Do not save the variable in ViewState in the Page_Load event if you change it again in PreRender.
