WebNumericEdit and Nullable<decimal>

I was binding Infragistics WebNumericEdit to a Nullable<decimal>. I had to set DataMode of control to NumericDataMode.Decimal. I set Nullable property to true since the value may be missing. (That is also the reason why we store the value as Nullable<decimal>.) It seemed working, but then I noticed that 0 is propagated to data instead of null. So it seems that Nullable<decimal> is not directly supported by WebNumericEdit.

After the short brainstorming, the decision was made to try to override the way how data are provided. Finally, this was sufficient to do:

public class WebNullableNumericEdit
   : WebNumericEdit
{
   public override object Value
   {
      get
      {
         return (this.Nullable && 
            this.Text.Equals(this.NullText)) ?
            null : base.Value; 
      }
      set { base.Value = value; }
   }
}
