I have a nested data object for a set of items within categories. Each category can contain sub categories and there is no set limit to the depth of sub categories. (A file system would have a similar structure.) It looks something like this:
class category
{
public int id;
public string name;
public IQueryable<category> categories;
public IQueryable<item> items;
}
class item
{
public int id;
public string name;
}
I am passing a list of categories to my
view as IQueryable<category>. I want to output the categories as a set of nested unordered list (<ul>) blocks. I could nest foreach loops, but then the depth of sub categories would be limited by the number of nested foreach blocks. In WinForms, I have done similar processing using recursion to populate a TreeView, but I haven't seen any examples of using recursion within an ASPX MVC
view.
Can recursion be done within an ASPX view? Are there other
view engines that include recursion for
view output?
