It can cause excessive page weight but this will not hurt your standing with the search engines. ViewState is stored in a hidden input which are mainly ignored by search engines.

some search engines only process the first few KBs of the page if the page size is large. As viewstate is a hidden input at the top of the form/page this can impact SEO as the actual content of the page may not get fully processed by the search engine if there is too much viewstate. Look into moving the viewstate to the bottom of the page.
