c# - Can I find out the return value before returning while debugging in Visual Studio -

-
take following function: datatable go() { return sometableadapter.getsomedata(); } when set breakpoint in function, there possibility inspect returned value? go() directly coupled datagrid in .aspx page. the way inspect returned datatable, use temporary variable. however, that's bit inconvenient. isn't there way? not know of. note if do add variable, removed compiler in release builds anyway... update: this functionality has been added vs2013 . can see return values in autos windows or use $returnvalue in watch/immediate window. the value can seen directly after returning function, easiest way access putting breakpoint on function call , step on (f10) call. update vs2015: boo! unfortunately, doesn't appear in vs2015 (devenv v14)

java - Retain scroll position in infinite RecycleView inside ScrollView (ANDROID) -

-
i have recycleview inside scrollview can infinite scroll , load new data paging. there way save scroll position (recycleview , scrollview) when activity onpause(), , restore when onresume(). instagram, facebook, etc. when click detail posting , timeline in same position when left before enter code here . my advice : use recycleview inside recycleview. recycleview can use strategy : 1) save last visible item position 2) manipulations 3) restore position int lastviewedposition = ((linearlayoutmanager)rv.getlayoutmanager()).findlastvisibleitemposition(); //some manipulations rv.getlayoutmanager().scrolltoposition(lastviewedposition + data.size() - 1);
