Me parece que puede corregir el código mediante el uso de OrderBy en GetFirst y GetNext parte de la Cláusula CON, pero no en el GetAll parte. El código correspondiente será sobre lo siguiente
ALTER PROCEDURE [dbo].[NewStoredProc]
(
@skip int,
@pageSize int,
@OrderBy Varchar(20),
@OrderByDirection Varchar(10)
)
AS
BEGIN
DECLARE @records int;
SET NOCOUNT ON;
SET @records =(select count(*) from Data where Status='A');
IF @skip <= 0
SELECT TOP (@pageSize) * from Data where Status='A'
ORDER BY CASE WHEN @OrderBy='Column1' AND @OrderByDirection='D'
THEN Column1
END DESC,
CASE WHEN @OrderBy='Column1' AND @OrderByDirection !='D'
THEN Column1
END,
CASE WHEN @OrderBy='Column2' AND @OrderByDirection='D'
THEN Column2
END DESC,
CASE WHEN @OrderBy='Column2' AND @OrderByDirection !='D'
THEN Column2
END,
CASE WHEN @OrderBy='Column3' AND @OrderByDirection='D'
THEN Column3
END DESC,
CASE WHEN @OrderBy='Column3' AND @OrderByDirection !='D'
THEN Column3
END
ELSE
WITH GetAll AS (
SELECT * from Data where Status='A'
),GetFirst AS (
SELECT TOP (@skip) *
FROM GetAll
ORDER BY CASE WHEN @OrderBy='Column1' AND @OrderByDirection='D'
THEN Column1
END DESC,
CASE WHEN @OrderBy='Column1' AND @OrderByDirection !='D'
THEN Column1
END,
CASE WHEN @OrderBy='Column2' AND @OrderByDirection='D'
THEN Column2
END DESC,
CASE WHEN @OrderBy='Column2' AND @OrderByDirection !='D'
THEN Column2
END,
CASE WHEN @OrderBy='Column3' AND @OrderByDirection='D'
THEN Column3
END DESC,
CASE WHEN @OrderBy='Column3' AND @OrderByDirection !='D'
THEN Column3
END
),GetNext AS (
SELECT TOP (@pageSize) nt.*
FROM GetAll AS nt
LEFT OUTER JOIN GetFirst AS f ON f.Col1=nt.Col1
WHERE f.Col1 IS NULL
ORDER BY CASE WHEN @OrderBy='Column1' AND @OrderByDirection='D'
THEN nt.Column1
END DESC,
CASE WHEN @OrderBy='Column1' AND @OrderByDirection !='D'
THEN nt.Column1
END,
CASE WHEN @OrderBy='Column2' AND @OrderByDirection='D'
THEN nt.Column2
END DESC,
CASE WHEN @OrderBy='Column2' AND @OrderByDirection !='D'
THEN nt.Column2
END,
CASE WHEN @OrderBy='Column3' AND @OrderByDirection='D'
THEN nt.Column3
END DESC,
CASE WHEN @OrderBy='Column3' AND @OrderByDirection !='D'
THEN nt.Column3

)
SELECT * FROM GetNext
RETURN @records;
END
