Creating your first report with NRapid


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.

Migrating an ASP.NET MVC 4 app from Azure websites to WinHost

About a week ago I've to migrate an ASP.NET MVC 4/EF5 application from Azure websites to WinHost. While the process was really smooth, there were some caveats related to database connections that I want to share with you. Create and setup the ftp profile on VS and configure the connection string was really easy, WinHost provide you those values and there is nothing special here. But once you deploy your website and try to see it online, you may get the “yellow screen of dead” with the message: "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)" Assuming you wrote the connection string properly, this happens because you cannot use the default connection name in your web.c

How to show excel files inside the .NET Webbrowser Control

If you are reading this, chances are you been banging your head against the wall for a couple of hours (or even days) trying to show excel files inside the WinForms webbrowser control. Possible reasons you ended up in here: You had working code that got broke after upgrading from Win 7. Your code doesn’t work the same way between machines running different (newer) versions of IE. A download box pops up every time your app tries to show an excel file inside the webbrowser control (you wanna show the actual content). You just have no clue on how to get excel working into the .NET embedded webbrowser control. You are trying to implement IInternetSecurityManager and don’t know where to start. (Or how don’t know how to delegate calls to your security manager). Among many other, maybe….. Yes, COM is a PITA, so is ActiveX and IE (Embedded or full for that matter). And no, showing excel files inside the webbrowser control shouldn’t be that hard, but sometimes we have

Moving to Medium

It's been a long time since I want to give medium a try, and finally, I made some time to do it. To get started on the new platform, I'll be doing series on "Getting programming concepts, languages and tools". If it sounds interesting to you, please take a look at the first post  Getting AWK  and spread the word if you like it. I'm not going to migrate old entries to the new web site. They will remain here safe and sound! As usual, thanks for reading!
