Hello, i am new to asp.net web service.
I want to send PlaceHolder from my main webform to web service, adding few controls there, and then return it back to my main webform. But,it doesn't seem to be working. It works fine when i return string.
This is code that gives me error :
public PlaceHolder ph(PlaceHolder a)
//some logic to add few controls to placeholder
Is it the limitation of web service? Any suggestion?
