Determine size of ASP.NET page's viewstate before serving page

Question

What ASP.NET page lifecycle event can I write code in to determine the size of the viewstate that being sent out? Also, is it possible to determine the size without parsing

Answer 1

You could use SaveStateCompleted, which occurs right after all the state has been saved to the viewstate. To know the size of the viewstate, just make a character count after calling ToString on the viewstate.

ViewState.ToString.Count()
