You could use a Mixin         lt summary gt      Adds  mixins  to the Boolean class       lt  summary gt  public static class BooleanMixins            lt summary gt          Converts the value of this instance to its equivalent string representation  either  Yes  or  No             lt  summary gt           lt param name  boolean  gt  lt  param gt           lt returns gt string lt  returns gt      public static string ToYesNoString this Boolean boolean                return boolean    Yes     No

Nope - but you could use a template column    lt script runat  server  gt    TResult Eval lt T  TResult gt  string field  Func lt T  TResult gt  converter         object o   DataBinder Eval Container DataItem  field        if  converter    null            return  TResult o              return converter  T o        lt  script gt    lt asp TemplateField gt     lt ItemTemplate gt        lt    Eval lt bool  string gt   Active   b   gt  b    Yes     No     gt     lt  ItemTemplate gt   lt  asp TemplateField gt
