RadPivotGrid control supports not only grouping by primitive types but it supports grouping by custom objects. By design the PivotGrid shows grouped data which is described into its fields by setting their DataField property. In most cases it is a primitive type (like string, integer, boolean, etc.). However you could set the DataField of some PivotGrid field to a custom object. For example if you have a custom class Product which has property ProductCategory which type is another custom class Category:
public class Product     
{         
   ...         
   public Category ProductCategory { get; set; }     
}
You could set the ProductCategory as DataField of the PivotGrid field and group by Category objects:
...     
<telerik:PivotGridRowField DataField="ProductCategory">     
</telerik:PivotGridRowField>     
... 
In this case you should override the GetHashCode, Equals and ToString() methods into the CategoryClass, also you need to implement IComparable interface and mark the class as Serializable. For example:
[Serializable] public class Category: IComparable 
{     
    public int CategoryID { get; set; }     
    public string CategoryName { get; set; }     
    public string Description {get;set;}      
    public override string ToString()     
    {         
        return CategoryID.ToString() + " " + CategoryName;     
    }      
    public override bool Equals(object obj)     
    {         
        Category category = obj as Category;         
        if (category != null)         
        {             
            return CategoryID.Equals(category.CategoryID) &&                      
            CategoryName.Equals(category.CategoryName) &&                     
            Description.Equals(category.Description);         
        }else{             
            return false;         
        }     
    }      
    public override int GetHashCode()     
    {         
        return CategoryID.GetHashCode() + CategoryName.GetHashCode() + Description.GetHashCode();     
    }      
    public int CompareTo(object obj)     
    {         
        return CategoryID.CompareTo(((Category)obj).CategoryID);     
    } 
}
