Data report in vb net9/13/2023 ![]() What is now evident is that, standing on what the IDE has made for us, for each report we must prepare a DataSet, binding all together on a single ReportViewer. It could now show us the fields presents in our - say - table.Īt 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 access The following image shows the first page of the wizard.Īnd that's the part of wizard in which we're asked to specify what entities should be used:Īfter selecting a connection type, and the objects to use, the wizard proceeds in creating a DataSet with a XSD file which represents its schema. We could see in the following image that there's a template named " Reports Application".Ĭonfirming to proceed with it will cause our IDE to: a) create a Form on which resides a ReportViewer,ī) create a Report1.rdlc, which is the graphical-rendered part of our report andĬ) starting a wizard to connect to a Data Source, selecting the objects that will became part of the business logic of our application. Open Visual Studio, select " New Project", then " Visual Basic" » " Reporting". In this article, i will show a method to achieve an almost 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 my case.īefore seeing how to bypass an explicit Data Source binding, let's see how Visual Studio normally manages a request of creating a new reporting application. In a word, i wanted to create an independent reporter, that could be used in any way needed by just launching it with differents option files. To the user, and the RDLC file to use for the report rendering through a ReportViewer control. My main target was toĪvoid having many dataset's schemas in different report applications, creating instead an application that could be feed with an option file, in which to specify the connection to be used, the query to be executed, the query parameters which must be asked I've found myself in the necessity of writing a reporting program unbounded from any IDE-generated datasets (or, more generally, not bounded to a predetermined connection), to be used to execute arbitrary queries in a graphical format. Visual Studio 2013 Community Edition (or later).RDLC file for later use, by passing to a ReportViewer control a dynamicĭata Source, originating - for example - directly from a query. You can also programmatically export the report that you created.In this article we'll see a method to use an existant Local Report with an arbitrary Data Source, or - in other words - how we can create/draw a Local Report in Visual Studio, saving the. When you create reports programmatically, you must use a Custom Report Source Resolver to display these reports in a Report Viewer that utilizes Telerik Reporting REST Service to render its reports. To create a functional report, you can add sections and items in code. The code sample above demonstrates how to create an empty report. ![]() ![]() sqlDataSource = new (connectionString, selectCommand) ĭim selectCommand As String = "SELECT * FROM Sales.Store"ĭim connectionString As String = "Data Source=(local)\SQLEXPRESS Initial Catalog=AdventureWorks Integrated Security=True"ĭim sqlDataSource As New (connectionString, selectCommand) String connectionString = "Data Source=(local)\\SQLEXPRESS Initial Catalog=AdventureWorks Integrated Security=True" String selectCommand = * FROM Sales.Store"
