c# - How to produce sum of each column in sql?

Question

i am trying to do column wise addition in Gridview but couldn't.

like i am filling gridview from store procedure which gives these values .

DateTime 10Quantity 20Quantity 30Quantity 10Amount 20Amount 30Amount GrandTotal
03/10/2015  792      0           594        7920        0     17820   25740
03/10/2015  332      3           194        9990        0     28220   38739

Expected:

DateTime 10Quantity 20Quantity 30Quantity 10Amount 20Amount 30Amount GrandTotal
03/10/2015  792      0           594        7920        0     17820   25740
03/10/2015  332      3           194        9990        0     28220   38739
Totals      1124     3           788        17910       0     46040   64479

i want a new row 'Totals' which should represent total for each column i.e. addition.

Code:

SP;

        with myquery ([DateTime],amount,Quantity) 
        as
        (
            select  Convert(varchar(20),serverdatetime,101) 'DateTime',amount,1 'Quantity'
                 from tickets
                 WHERE CONVERT(DATE,ServerDateTime) BETWEEN @FromDate and @ToDate
        )
        select *, 10 * c.[10Quantity] '10Amount',20 * c.[20Quantity] '20Amount',30 * c.[30Quantity] '30Amount',((10 * c.[10Quantity])+(20 * c.[20Quantity])+(30 * c.[30Quantity]))'GrandTotal' from (
        SELECT DateTime,[10] AS '10Quantity', [20] AS '20Quantity', [30] AS '30Quantity'
        FROM 
        (SELECT [DateTime], amount,quantity
        FROM myquery) p
        PIVOT
        (
        COUNT ([Quantity])
        FOR [Amount] IN
        ( [10], [20], [30])
        ) AS pvt
        ) as c
    END

i must do it from front end i.e. gridview

Answer 1

Use the RowDataBound event handler to evaluate data (sum columns) when they are added to the GridView.

And add a footer to show the totals.

Take a look at this: https://msdn.microsoft.com/en-us/library/bb310552.aspx STEP 3: solution 2. That is how you use an eventhandler to run totals in a GridView.
