Debug issue in visual studio 2017 ?

It seems the click event might not be wired up correctly. Create a new click event and see if that hits the breakpoint. If it does, verify the original click event is working properly and wired up.

Did all posibilities but not getting the debug

May be you have opened same file twice and changed code in both files but saved only one file and kept breakpoint in another opened same file. Please close all opened files, save, clean all solutions and build it. https://stackoverflow.com/questions/2468852/the-breakpoint-will-not-currently-be-hit-the-source-code-is-different-from-the https://developercommunity.visualstudio.com/content/problem/96231/the-breakpoint-will-not-currently-be-hit-the-sourc.html https://forums.asp.net/t/1054250.aspx?HELP+The+breakpoint+will+not+currently+be+hit+The+source+code+is+different+then+the+original+version https://www.aspforums.net/Threads/129787/Visual-Studio-The-break-point-will-not-currently-be-hitThe-source-code-is-different-from-original-version/

Hey probably you didn't wrote any onclick event. So check that first. Thanks.

Possibilities are : event may not be attached to button. Another may be solution not builded properly just clean build then build it.
