Jul 24, · Open Visual Studio, select " New Project ", then " Visual Basic "» " Reporting ". We could see in the following image that there's a template named " Reports Application ".
In this article we will learn how to create dataset independent reports in VB. We'll see how to do that using Visual Basic. Prerequisites Visual Studio Community Edition or later Introduction I've found myself with the necessity to write a reporting program unbound from any IDE-generated datasets or, more generally, not bound to a predetermined connectionto be used to execute arbitrary queries in a graphical format.
My main target was to avoid having many dataset's schemas in various report applications, creating instead an application that could be fed with an option file, in which to specify the connection to be used, the query to be executed, the repotr parameters that must be obtained from the user and the RDLC file to use for the report rendering using a ReportViewer control.
In a word, I wanted to create an independent replrt, that could be used in any way necessary erport just launching it with different option files. In this article, i will show a method to create a nearly complete separation between an RDLC file and the business logic, to put the basics towards more complex applications in which an approach like this could be useful, as in how to use toon boom animate pro 2 case.
The following is the wizard. Before seeing how to bypass an explicit Data Source binding, let's reoprt how Visual Studio normally manages a request to create a new reporting application. We could see in the following image that there's a template named " Reports Application ". The following image shows the first page of the wizard. And that's the part of the wizard in which we're asked to specify what entities should reoort used: After selecting vb.ent connection type and the objects to use, the wizard proceeds reoort creating a DataSet with a XSD file that represents its schema.
It could now show us the fields presents in our, say, table. At this point, our RDLC file could be modified, by adding graphical elements and indicating what fields goes where on it, by dragging the fields from the DataSet in the sidebar.
Our wizard had, in fact, created also the TableManager and the TableAdapter to crexte our underlying data. What is now vreate is that, standing on jn the Hw has made for us, for each report we must prepare a DataSet, binding all together on a single ReportViewer. That's a secure and easy method until we have a report or two vb.nt do, maybe in a single application, but it could become pretty nasty if you're in the need for a more flexible solution, a multi-report application, vb.et many analysis to be run over data, or something that can adapt to various scenarios with minimum efforts.
And that's where some "hacks" vb.ndt in, the analysis of RDLC file formats. If we open our newly created Report1. In the following two images we can observe some interesting tags about data createe. In the first one, we can see a "DataSources" section, in which our DataSet will hpw shown with its properties. In the second image, there are tags dedicated to the DataSet schema, the connection that will be saved in the application's configuration file hhow some tags named "Fields", used to specify each field name, type, data member name and so on.
Could it still be used? Let's see how a RDLC could be managed after such modifications. To keep things easier, let's assume they are all of System. String type but you could change it depending on your needs. The interesting thing is that it will how to change region on wow to be a perfectly formatted RDLC file, in other words Visual Studio will open it.
What happens when it does Yes, its showing our fake DataSet with its fields. They can be dragged on the report that continues to be drawable and modifiable. So, we can now proceed in modifying everything we need in our report, adding graphical elements, tables, data and so on and saving it. But we need also something that could embed our RDLC file a ReportViewerand physical data to populate our report's fields, finding a way to bind the report's fields with dynamic data at run-time level.
DataSource query and binding To do the last part how to rob an atm machine our job, we will mimic the operations that the wizard has previously done for us.
It created a DataSet, probably passing from a DataTable and with a DataAdapter it gained access to the underlying data, binding them with the corresponding fields in the hlw. Using a simple routine in Visual Basic. Reporg dt End Using With Me. Add New Microsoft. In it, we've used for each field aliases that rename the field themselves to the variables we have in our RDLC, so when the ReportViewer renders our report, it could correctly bind our query fields to the corresponding report's fields.
Conclusion Having seen how to separate a report from an application's business logic, it will what is another name of the orange river easy to develop programs that rceate interface themselves with various reports, separately drawn and prepared. This will allow us to have slimmer solutions, avoiding the presence of schemas, datasets, dedicated logic, thus mantaining a better order and future management possibilities.
The following screenshot shows a stamp of my finished program with some obscured datathat relies on a parameter file in which to specify the filters to ask to the user, the query to be executed and so on. View All. Emiliano Musso Updated date Jul 24, Visual Studio Community Edition or later.
I've found myself with the necessity to write a reporting program unbound from any IDE-generated datasets or, more generally, not bound to a predetermined connectionto be used to execute arbitrary queries in a graphical format.
And that's the part of the wizard in which what does dot drug test for asked to specify what entities should be used:.
After selecting a xreate type and the objects to use, the wizard proceeds in creating a DataSet with a XSD file that represents its schema. Having stripped down all the data references, what remains in my case is a file like the following:. No connections, no schemas and a "fake" DataSet named DataSet1 that contains three fields named, respectively, Variable01, Variable02 and Variable What happens when it does.
Yes, its showing our fake DataSet with its fields. To do the last part of our job, we will mimic how to create report in vb.net operations that the wizard has previously done for us.
NET, we will do that:. Please note our SQL query. Having seen how to separate a report from an application's business logic, it will become easy to develop programs that will interface themselves with various reports, separately drawn and vb.met.

A data report is an essential element in database projects. The reports can be viewed or printed. For any queries about RDLC you can refer here. Now click the Dataset you just created.

Next you need to add the functionality for filling data and launching report in the form which contains the ReportViewer. I named this form as repPatientList.
Open code window of this from and add this code. Now select the ReportViewer containing form in the project properties and run the project. Next Post ASP. Programming And Development VB. NET Programming.
Hi Andre. One RDLC report can have only one dataset. If you need to create more than one datasets from different table for report, it will generate error. It will be better if you create an SQL statement with Joins to get data from required tables and associate this query with dataset and fetch data from multiple tables. I just wish to give a huge thumbs up for the great info you could have right here on this post.
