    Hello,

    I created a new combobox class and used the RadDropDownList as base class, but when I override the CreateDropDownListElement function and return my own element, a black border appears:

    public class TestComboBox : RadDropDownList
        {
            public override string ThemeClassName
            {
                get
                {
                    return typeof(RadDropDownList).FullName;
                }
                set
                {
                    base.ThemeClassName = value;
                }
            }
     
            protected override RadDropDownListElement CreateDropDownListElement()
            {
                //return base.CreateDropDownListElement();
                return new TestElement(this);
            }
        }
     
        public class TestElement : RadDropDownListElement
        {
            public TestElement()
            {
                //
            }
     
            public TestElement(object owner)
                : base(owner)
            {
                //
            }
     
        }
