Try this?

SELECT
    [ID]
    , [Date List]
    , [Name]
    , [No]
FROM
    (
    SELECT
         *
       , ROW_NUMBER() OVER ( PARTITION BY [ID] ORDER BY [Date List] DESC) AS [SortID]
    FROM
        <TheTable>
    )
    AS s
WHERE
    [SortID] = 1

SELECT t.*
FROM table t
CROSS APPLY(
SELECT MAX([Date List])AS MaxDate
FROM table
WHERE ID = t.ID
)t1
WHERE MaxDate = t.[Date List]

visakh's suggestion could give you multiple results for each partition if the dates are not unique -- mine will give a random 1....

Neither of these behaviors are particularly desirable! You can add more clauses to the ORDER BY of ROW_NUMBER however..
