CommandManager MetaGrid Class Not Found

Vote:
 

I've been following the tutorials of hwo to custimze commerce but I hit a stubling block. I followed these articles to get the buttons and handler to work:

In the second article, it uses this class named MetaGrid to get the checked collections but that class isn't recognized and I can't find the appropriate class path to it. Here's the example code:

string[] selectedElements = MetaGrid.GetCheckedCollection(((CommandManager)Sender).Page, cp.CommandArguments["GridId"]);

I need some similar to this to get the collection of checked elements to get the handler to work completely. Does anyone have any ideas on if the class exists or another way of implementing this?
