Adding Event Handler for Windows Application Dialog box

I would like to an add event handler to my simple GUI application made with a windows application in Visual Studio 2013. I have seen that you can use the Resource View to create windows, buttons, etc. However, whenever I right-click and see the option to "Add Event Handler..." it is always grayed out. I saw in this post Visual Studio 2013 and C# - Unable to add event handler to try creating a new project and/or restart VS, both of which I tried. Am I making some newbie mistake?? Why can't I add an event handler? Any suggestions would be great. Thanks.
