asp.net web api - Ajax Web-Api optional parameter null issue. -

-

ajax webapi when parameter null or blank 400 bad reuqsest occurs. solution needed asap.

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

here buildtypename optional parameter when there not search parameter passed how reduce 400 error.

//controller

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

here issue buildtype.

help one.

regards

you need change way request made. either complete request string adding ="" end, or leave out buildtypename parameter when empty.

so either of these 2 cases:

/api/buildtypewebapi/getbuildtypelist?currpage=1&pagesize=10&buildtypename=""

/api/buildtypewebapi/getbuildtypelist?currpage=1&pagesize=10

this way, web api knows want buildtypename parameter. in case incomplete request.
