c++ - UWP/WinRT: How to enable undo hooks on a TextBox? -

-

the textbox class supports undo, present , functional in context menu.

i implement undo/redo buttons found in every common document editor such microsoft word. disabled when have no action take, , when there undo/redo stack move through, pressing buttons cause textbox's contents undo , redo.

looking @ textbox api, there doesn't seem mention of how hook undo data. discussion mention undo present on context menu.

how undo/redo hooks implemented on textbox?

if makes difference, i'm coding in c++/cx.

you can record history manually textchanged event. undo command used display input. hook control seems not possible.

handle contextmenuopening event textbox , can modify popup own commands, example own undo/redo history.

a sample: https://code.msdn.microsoft.com/windowsapps/context-menu-sample-40840351 works fine uwp.

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
