    I have 2 observable collections. one contains list of items. and 2one contains subitems. one item may have multiple subitems (one to many relationship)
    E.g.  1st collections: 1. Animal  2. Bird  3.Vgetable
    Now , in 2nd collections has sub-items

    Subitem number  Subitem name    Item Number
    1                             Horse                   1
    2                             Elepahant            1
    3                              Parrot                  2

     Now, on combo box i want to show each subitems under head of its corresponding Itemnumber.

    See below.

       -- Horse
       -- Elephant

    While each item number is a separtor over here and  must be disbaled but sub-itemnumber must be enabled.

      How to achieve all these things in silverlight

    Hello Thomas,

    Since RadComboBox has only one ItemsSource, you should merge the two collections into one, apply some kind of sort, so they appear in the correct order, then using a StyleSelector apply different styles on the "separator" items and the normal items:
