custom controls - overwrite backcolor for ovalshape -


i'm trying use backcolor variable fill ovalshape. i'm doing because need set color @ runtime , custom control uses fillcolor instead of backcolor. color changed @ runtime using propertygrid.

i'm overwriting backcolor , works until click on ovalshape. if click on oval colors entire control not oval.

public override color backcolor     {                 {             if (oval == null)             {                 return color.transparent;             }             else             {                 return oval.fillcolor;             }         }         set         {             if (oval == null)             {                 base.backcolor = color.transparent;                 if (sc != null)                     sc.backcolor = color.transparent;             }             else             {                 base.backcolor = color.transparent;                 if (sc != null)                     sc.backcolor = color.transparent;                 oval.fillcolor = value;             }          }     }
