asp.net - How to share a variable value with a webmethod? -


i have code:

 dim main_id int    protected sub page_load(byval sender object, byval e system.eventargs) handles me.load     main_id =1 end sub  <webmethod()> _ public shared function bindpersonnel(byval product_id string) string    dim project_id int16    project_id=main_id 'this doesn't work  end function

on page load, set value of variable main_id , need way somehow share main_id webmethod function, how can done? have not tried session variable , don't want use session variable. found link accessing common variable in webmethod , jquery can't figure out how going solve problem. read posts using hidden field, requires me go 2 trips. love avoid that.

webmethods independent of other variables on page. if want access main_id, declare private shared main_id integer, cause of users have access same id value, don't want.

perhaps easiest way store value in sessionstate, , enable sessionstate access in webmethod. on other hand, removes asynchronous-like functionality looking (it may not issue).

sessionstate give ability have per-session value (avoiding use of shared solution mentioned above).

protected sub page_load(byval sender object, byval e system.eventargs) handles    me.load     session("main_id") = 1 end sub  <webmethod(enablesession:=true)> public shared function bindpersonnel(byval product_id string) string    dim project_id integer = cint(httpcontext.current.session("main_id")) end function
