asp.net mvc 4 - Web-Api 400 BadRequest when search parameter is blank -

-

i using web-api mvc4

i making searching functionality, in cases if filter data remove textbox value , press search button, need show whole listing in case showing 400 bad request. search parameter blank, know if search parameter blank throw 400 error web-api.

any 1 have proper solution please let me know.

data: "currpage=" + jscurrpage + "&pagesize=" + parseint(pagesize) + "&buildtypename=" + $("#buildtypename").val(),

here in cases buildtype blank. when search made

//controller

public httpresponsemessage getbuildtypelist(int currpage, int pagesize, string buildtypename)         {          }

net -> xhr url :

http://{parenturl}/api/buildtypewebapi/getbuildtypelist?currpage=1&pagesize=10&buildtypename=

if allow currpage , pagesize empty, need accept nullable ints:

public httpresponsemessage getbuildtypelist(int? currpage, int? pagesize, string buildtypename)

then, you'll update query return entire list if no filter values provided.
