    Hi Mohamed,

    Thank you for writing.

    You should create a Binding and use it Format and Parse events to convert from String to Color and vice versa. For example:
    public partial class RadForm1 : Telerik.WinControls.UI.RadForm
        public RadForm1()
            BindingList<ColorInfo> colorNames = new BindingList<ColorInfo>();
            colorNames.Add(new ColorInfo() { ColorName = "Red" });
            colorNames.Add(new ColorInfo() { ColorName = "Green" });
            colorNames.Add(new ColorInfo() { ColorName = "Blue" });
            BindingSource source = new BindingSource();
            source.DataSource = colorNames;
            radBindingNavigator1.BindingSource = source;    
            Binding binding = new Binding("Value", source, "ColorName", true);
            binding.Format += binding_Format;
            binding.Parse += binding_Parse;
        void binding_Format(object sender, ConvertEventArgs e)
            string val = e.Value.ToString();
            switch (val)
                case "Red":
                    e.Value = Color.Red;
                case "Blue":
                    e.Value = Color.Blue;
                case "Green":
                    e.Value = Color.Green;
                    e.Value = Color.FromArgb(int.Parse(e.Value.ToString()));
        void binding_Parse(object sender, ConvertEventArgs e)
            e.Value = ((Color)e.Value).ToArgb().ToString();
    class ColorInfo
        public string ColorName { get; set; }

    I hope this will be useful.
