It is not clear what you meant... Perhaps a trigger 
CREATE TRIGGER ShowUpdatedColumns ON Test FOR UPDATE
AS
DECLARE @ColumnID int, @Columns nvarchar(4000), @ObjectID int, @LastColumnID int
SET @ObjectID=(SELECT id FROM sysobjects WHERE name='test')
SET @LastColumnID=(SELECT MAX(colid) FROM syscolumns WHERE id=@ObjectID)
SET @ColumnID=1
WHILE @ColumnID<=@LastColumnID BEGIN
IF (SUBSTRING(COLUMNS_UPDATED(),(@ColumnID - 1) / 8 + 1, 1)) &
POWER(2, (@ColumnID - 1) % 8) = POWER(2, (@ColumnID - 1) % 8)
SET @Columns = ISNULL(@Columns+',','') + COL_NAME(@ObjectID,@ColumnID)
SET @ColumnID=@ColumnID+1
END
PRINT 'Updated columns are :' + @Columns
