问题 I have been tasked with porting an old app to MVC 3, and want to use EF's code first to replicate its existing database schema.

问题 So, I'm running these Selenium IDE tests against a site I'm working on. Everything about the tests themselves is running fine, except I would like to do a bit of clean-up once I'm done. In my MVC3 Razor based site, I have a JavaScript file with a function that gets a JsonResult from a Controller of mine.

问题 Having googling for some time, I'm a little bit confused with how to do this in asp mvc 3. So, the task is to have a common layout (or master?) page for several controllers' views.

问题 I have a problem with my jqGrid. I have seen other posts here with similar problem, except that mine is particular in that the data is loading correctly in my development machine but when I publish the site on my production server, the jqGrid won't load the data, all I get is an empty grid.
