c# - Add a new property to an ASP.NET dropdownlist -

i need add new property asp.net dropdownlist called scoretitle. accepts 4 values , need intellisense show 4 values (e.g value1, value2,value3, , value4).

public class scoredropdownlist : dropdownlist     {         private string _scoretitle;          public string scoretitle         {                         {                 return _scoretitle;             }             set             {                 _scoretitle = value;             }         }           public scoredropdownlist() : base()         {             (int = 0; <= 10; i++)             {                 items.add(new listitem(i.tostring()));             }         } }  

markup:

<mobile:scoredropdownlist id="ddltidiness" scoretitle="value1" runat="server" cssclass="input-mini inline" /> 

how can add scoretitle property , make 4 values appear when setting the scoretitle?

make score title enum type.

public enum scoretitle {     none,     win,     loss,     deuce } 

then

    public scoretitle scoretitle     {         get;         set;     }
