Search GridView records (data) on TextBox KeyPress using jQuery in ASP.Net

In order to search GridView records (data) on TextBox KeyPress event, I am making use of jQuery QuickSearch Plugin which dynamically searches the GridView cells and filters out the unwanted rows and displays only the records (data) that matches the input search term.

Get Table Size in SQL Server 2008

To get table size in SQL server we need to write the query like as shown below

SQL Server - How to Get Database Size in SQL Server 2008

To get database size in SQL server we need to write the query like as shown below


SELECT
database_name = DB_NAME(database_id)
, log_size_mb = CAST(SUM(CASE WHEN type_desc = 'LOG' THEN size END) * 8. / 1024 AS DECIMAL(8,2))
, row_size_mb = CAST(SUM(CASE WHEN type_desc = 'ROWS' THEN size END) * 8. / 1024 ASDECIMAL(8,2))
, total_size_mb = CAST(SUM(size) * 8. / 1024 AS DECIMAL(8,2))
FROM sys.master_files WITH(NOWAIT)
WHERE DB_NAME(database_id) = 'master' –-- your database name
GROUP BY database_id


Once we run above code we will get output like as shown below

Inner join with Group by and case statement in Linq to sql


I have the following sql below which I am having real trouble getting into a LINQ statement. The specific issue is that for one of the fields I am using a CASE statement both in the select and has part of the HAVING clause. Various reasons why i needed to do this but I cant seem to reproduce it in LINQ.
Here is the sql Query
select Count (DetailID) as MonthCount ,
StoreID, DetailID,
SUM(Amount ) as AnnualAmount, PAYear,
MIN(CASE when ExportFlag = 'SUCCESS' then 1 when ExportFlag is NULL or
ExportFlag = '' then 0 else - 1 end) as ExpFlag
from  Input_Financials
inner join DestinationDetail cdd on
cdd.ID =Financials.DetailID
group by StoreID, DetailID, PAYear
Having MIN (CASE when ExportFlag = 'SUCCESS' then 1 when ExportFlag is NULL
then 0 else -1 end ) = 0
and Count (*) >= 1
order by PAYear
Convert This query in Linq to Sql
var query = from inf in inputActs
join cgrdets in cgrDetails on inf.DestinationDetailID
equals cgrdets.ID
            let export = (inf.ExportFlag == "SUCCESS" ? 2:
inf.ExportFlag== "ERROR" ? 1:
            inf.ExportFlag == null ? 0: 99)
group inf by new {export, inf.StoreID
inf.DestinationDetailID,inf.PAYr } into g
where g.Key.export == 0
select new { MonthCount = g.Count(), g.Key.StoreID,
g.Key.PAYr,Amount = g.Sum(inf=>inf.Amount) };

please ignore some minor discrepancies you may find in naming of fields between these two - its just probably because i renamed some quickly for the sake of this question.
