if remove @id = "profileform" attribute below getting httppostedfilebase (imageupload) value.

@using (html.beginform("update", "profile", new { profileid = viewbag.profileid }, formmethod.post, new { @enctype = "multipart/form-data"})) {  } 

i need pass both id , enctype - can please suggest me doing wrong or there better way ?

after wasting lot of time thing helpful you.just use

@using (html.beginform("update", "profile", new { @id = "profileform" }, formmethod.post, new { @enctype = "multipart/form-data", }))

your id there new { @id = "profileform" }
