No one concern about this topic?

I'm interested in categories, but I don't understand your problem! Can you explain a little more?

To get the first category you use:

CategoryManager.GetAllCategories(0) //Zero means the root (parent) category... since we are getting the first category root is 0.

To get all others category you have to loop the first category... something like:

var cats = CategoryManager.GetAllCategories(0);
foreach (var cat in cats)
{
     var secondC = CategoryManager.GetAllCategories(cat.CategoryId);
     //do something with secondC
}

yeah!

and the 3rd catagory?
