Crystal Report in Asp.net by code

1. right click on project in solution explorer and add new dataset in project.
2. create table on this dataset with field which you want to show in report.
3. from solution explorer add new crystal report and in wizard of crystal report select that dataset and table which you just created for report
4. add new form or take an existing form in project and add crystal report viewer on that form in which we will show our report.
5. write below code in crystal report viewer's form
//header file need to include
using CrystalDecisions.Shared;
using CrystalDecisions.CrystalReports.Engine ;

//code
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindReport();

CrystalReportViewer1.ShowFirstPage();
}
}
private void BindReport()
{ string servername= System.Configuration.ConfigurationManager.AppSettings["servername"].ToString();
string databasename=ConfigurationManager.AppSettings["databasename"].ToString();
string userid=ConfigurationManager.AppSettings["userid"].ToString();
string password=ConfigurationManager.AppSettings["password"].ToString();


CrystalDecisions.Shared.TableLogOnInfo mylogin = new TableLogOnInfo();
CrystalReportFormSaleInquiry crinq = new CrystalReportFormSaleInquiry();
//object of business logic layer to get data from database
BLL.BLLMIS.BLLFormSale formsale = new KIDZEE.BLL.BLLMIS.BLLFormSale();
//to get data from database in datatable
DataTable dtrpt = formsale.SelectMISformsale(new Guid(Session["inquiryid"].ToString()));

foreach (CrystalDecisions.CrystalReports.Engine.Table tblrpt in crinq.Database.Tables)
{
mylogin=tblrpt.LogOnInfo;
mylogin.ConnectionInfo.DatabaseName=databasename;
mylogin.ConnectionInfo.ServerName=servername;
mylogin.ConnectionInfo.UserID=userid;
mylogin.ConnectionInfo.Password=password;
tblrpt.ApplyLogOnInfo(mylogin);
tblrpt.SetDataSource(dtrpt);
CrystalReportViewer1.ReportSource = crinq;
//exporting Report to Pdf
MemoryStream oStream; // using System.IO
oStream = (MemoryStream)
crinq.ExportToStream(
CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
Response.Clear();
Response.Buffer = true;
Response.ContentType = "application/pdf";
Response.BinaryWrite(oStream.ToArray());
Response.End();

DateTime Functions

DateTime Function
-- to get resutl like Oct2007-May2009 from two dates
-- use below function like this

select dbo.frommonthyeartomonthyear('10/09/2007','05/03/2009')

create function FromMonthYearToMonthYear(@FromDate datetime,@ToDate datetime)
returns nvarchar(15)
begin
return left(DATENAME(month, @FromDate),3)+''+ convert(nvarchar(4), year(@FromDate))
+'-'+left(DATENAME(month, @ToDate),3)+''+ convert(nvarchar(4), year(@ToDate))
end


create  function DateOnly(@DateTime DateTime)
-- Returns @DateTime at midnight; i.e., it removes the time portion of a DateTime value.
returns datetime
as
begin
return dateadd(dd,0, datediff(dd,0,@DateTime))
end
go

create function Date(@Year int, @Month int, @Day int)
-- returns a datetime value for the specified year, month and day
returns datetime
as
begin
return dateadd(month,((@Year-1900)*12)+@Month-1,@Day-1)
end
go

create function Time(@Hour int, @Minute int, @Second int)
-- Returns a datetime value for the specified time at the "base" date (1/1/1900)
returns datetime
as
begin
return dateadd(ss,(@Hour*3600)+(@Minute*60)+@Second,0)
end
go

create function TimeOnly(@DateTime DateTime)
-- returns only the time portion of a DateTime, at the "base" date (1/1/1900)
returns datetime
as
begin
return dateadd(day, -datediff(day, 0, @datetime), @datetime)
end
go

create function DateTime(@Year int, @Month int, @Day int, @Hour int, @Minute int, @Second int)
-- returns a dateTime value for the date and time specified.
returns datetime
as
begin
return dbo.Date(@Year,@Month,@Day) + dbo.Time(@Hour, @Minute,@Second)
end
go

Remember that you must prefix UDFs with the owner (usually dbo) when calling them.

Usage Examples:

where TransactionDate >= dbo.Date(2005,1,2)  -- no formatting or implicit string conversions needed for date literals

select dbo.Date(year(getdate()), 1,1) -- returns the first day of the year for the current year.

select dbo.DateOnly(getdate()) -- returns only the date portion of the current day.

if dbo.TimeOnly(SomeDate) = dbo.Time(5,30,0)  -- check to see if the time for a given date is at 5:30 AM

select dbo.Date(year(getdate()), month(getdate()),1) -- returns the first day of the current month.

select dbo.Date(year(getdate()), month(getdate())+1,0) -- returns the last day of the current month.

where SomeDate >= dbo.DateOnly(getdate()) and SomeDate < dbo.DateOnly(getDate())+1 -- a simple way to get all transactions that occurred on the current date

select dbo.DateOnly(getdate()) + 1 + dbo.Time(14,30,0) -- returns tomorrow at 2:30 PM.
and so on ....

Part II: Introducing TimeSpans to SQL Server With those functions in place, we can add two more that will give us further flexibility when working with dates and times: The concept of a "TimeSpan", very similar to what is available in the .NET framework. -- to get time only with AM/PM and no date

create function TimeOnlyNODate(@DateTime DateTime)
returns char(26)
as
begin
return LTRIM(RIGHT(CONVERT(CHAR(26),@DateTime,109),14))
end
select dbo.timeonlynodate(getdate())
select LTRIM(RIGHT(CONVERT(CHAR(26),GETDATE(),109),14))

create function TimeSpan(@Days int, @Hours int, @Minutes int, @Seconds int)
-- returns a datetime the specified # of days/hours/minutes/seconds from the "base" date of 1/1/1900 (a "TimeSpan")
returns datetime
as
begin
return dbo.Time(@Hours,@Minutes,@Seconds) + @Days
end

create function TimeSpanUnits(@Unit char(1), @TimeSpan datetime)
-- returns the # of units specified in the TimeSpan.
-- The Unit parameter can be: "d" = days, "h" = hours, "m" = minutes, "s" = seconds
returns int
as
begin
return case @Unit 
when 'd' then datediff(day, 0, @TimeSpan)
when 'h' then datediff(hour, 0, @TimeSpan)
when 'm' then datediff(minute, 0, @TimeSpan)
when 's' then datediff(second, 0, @TimeSpan)
else Null end
end

Here, a TimeSpan is just a datetime offset from the "base" date of 1/1/1900. Creating one is the same as creating a Time using the Time() function, but we have added a parameter for Days to give more flexibility. The TimeSpanUnits() function works similar to standard T-SQL DatePart() function, but it returns the total # of units in the given time span. So, if you create a time span of 1 day and 2 hours, then TimeSpanUnits("d") will return 1 and TimeSpanUnits("h") will return 26. Negative values can be returned as well. You also may wish to implement the TimeSpanUnits() function as multiple functions, one per unit (e.g., TimeSpanHours(), TimeSpanDays(), etc) depending on your preference. Of course, a simple way to create a TimeSpan is to simply subtract two standard T-SQL DateTimes. Also please note that we can add and subtract Dates, Times, and TimeSpans all together using standard + and - operators and everything will work as expected. We can also add integers to our Dates and Times which will add entire days to the values. Here's a TimeSpan usage example:

declare @Deadline datetime -- remember, we still use standard datetimes for everything, include TimeSpans
set @Deadline = dbo.TimeSpan(2,0,0,0)   -- the deadline is two days

declare @CreateDate datetime
declare @ResponseDate datetime

set @CreateDate = dbo.DateTime(2006,1,3,8,30,0)  -- Jan 3, 2006, 8:30 AM
set @ResponseDate = getdate() -- today

-- See if the response date is past the deadline:
select case when @ResponseDate > @CreateDate + @Deadline then 'overdue.' else 'on time.' end as Result

-- Find out how many total hours it took to respond:   
declare @TimeToRepond datetime
set @TimeToRespond = @ResponseDate - @CreateDate

select dbo.TimeSpanUnits('h', @TimeToRespond) as ResponseTotalHours

-- Return the response time as # of days, # of hours, # of minutes:
select dbo.TimeSpanUnits('d',@TimeToRespond) as Days, DatePart(hour, @TimeToRespond) as Hours, DatePart(minute, @TimeToRespond) as Minutes

-- Return two days and two hours from now:
select getdate() + dbo.TimeSpan(2,2,0,0)
