How do I make the "category" field a required one for adding and editing events? In other words, I need it so that the users have to select one of the categories when they add or modify events?
When I look at the markup of the Events control templates, they have this for the Category field:
<sfCtg:CategoriesField ID="Category" runat="server" />
... and I don't know how to make that required.
