    HI, I want to use GridViewComboBoxColumn in a radgridview. But I found if I use RadWindow to hold the radgridview, the combobox dropdown list could not show. However, it could work if I create my own window.
    Please see my attachment code.
     public class Player
        {
            public string Name
            {
                get;
                set;
            }
     
            public Position Position
            {
            get;
            set;
            }
     
            public Player(string name, Position pos)
            {
                Name = name;
                Position = pos;
            }
        
        }
     public enum Position
        {
            [Description("China")]
            GB,
            [Description("Unite Kingdom")]
            UK,
            [Description("Unite States")]
            US
        }
    public class ViewModel
        {
            private List<Player> allPlayers;
            public ObservableCollection<Player> AllPlayers
            {
                get
                {
                    if (this.allPlayers == null)
                    {
                        this.allPlayers = new List<Player>();
                        this.allPlayers.Add(new Player("Haibng"Position.GB));
                        this.allPlayers.Add(new Player("WHS"Position.UK));
                        this.allPlayers.Add(new Player("NY"Position.US));
     
                    }
                    return new ObservableCollection<Player>(this.allPlayers);
                }
            }
     
            public IEnumerable<Telerik.Windows.Data.EnumMemberViewModel> Positions
            {
                get
                {
                    return Telerik.Windows.Data.EnumDataSource.FromType<Position>();
                }
            }
        }

    Hello Ke,

    We are aware of this problem and it should be fixed in the latest internal build. The fix also should be included in the upcoming beta version.

    Best wishes,
