    Hi,
    I'm currently upgrading a solution from telerik controls from 2010 to telerik controls from 2013. 
    In our solution we have a class inheriting from RadComboBoxItem.
    This control appears to have been deprecated. What control can I inherit from in telerik 2013 to achieve the same behaviour? Thanks.
    Dave

    Hello David,

    Thank you for writing.

    You need to inherit from RadDropDownListElement and RadDropDownList. A simple implementation would look like this:
    public class RadCustomDropDownList : RadDropDownList
    {
        protected override RadDropDownListElement CreateDropDownListElement()
        {
            return new RadCustomDropDownItem();
        }
     
        public override string ThemeClassName
        {
            get { return typeof(RadDropDownList).FullName; }
            set { }
        }
    }
     
    public class RadCustomDropDownItem : RadDropDownListElement
    {
        public RadCustomDropDownItem()
            : base()
        {
        }
     
        public RadCustomDropDownItem(object owner)
            :base(owner)
        {
        }
     
        public RadCustomDropDownItem(string text)
            : this()
        {
            this.Text = text;
        }
     
        public RadCustomDropDownItem(string text, string tag)
            : this(text)
        {
            this.Tag = tag;
        }
     
        protected override Type ThemeEffectiveType
        {
            get { return typeof(RadDropDownListElement); }
        }
    }

    Additionally you can find a more advanced implementation in our Code Library on this address.

    I hope this helps.
