In this
post, I’m going to build a very basic report with NRapid to show some records from the Categories table in the Northwind database. The goal of this post is provide
a sneak peak of the reporting capabilities of NRapid.
The first
thing we have to do in order to work with NRapid, is configure the database
connection in the app.config file. Once this setting is done, we will be able
to let NRapid to take care of the data access.
To create
our first report, we just need add a class that inherits from
NRapid.Core.Reporting.Report and implement two abstract members.
The first
one is a method called ConfigureReport, wich will be invoked by the report
engine at run time and will allow us to add tables, groups, footers, etc. to
the report.
The second
is a property where we have to specify the report's title.
In this
case, we need to show the whole list of categories from the Northwind data
base, we are not filtering any data, so we are just going to ignore viewdata
parameter (it’ll be covered in upcoming posts) and write a SQL query and add
the table to the report. As you can see in the image below, we can use the
NRapid session to go to the data base and fetch the records, it’s really easy.
The last
step is executing the report, which can be done by using the NRapid Report
Manager.
And the
report should look something like this
So that’s
it for now, not too bad for less than then lines of code ;)
In upcoming
post, I’ll be covering how to use the view data to provide filtering
capabilities.
