Utilizzo del controllo Web Form ReportViewerUsing the WebForms ReportViewer Control

Per visualizzare i report distribuiti in un server di report o presenti in un file system locale, è possibile utilizzare il controllo Web Form ReportViewer per eseguirne il rendering in un'applicazione Web.To view reports deployed to a report server or reports that exist on the local file system, you can use the WebForms ReportViewer control to render them in a Web application.

Per utilizzare il controllo ReportViewer in un'applicazione WebTo use the ReportViewer Control in a Web application

  1. Creare un nuovo sito Web MicrosoftMicrosoft ASP.NET usando MicrosoftMicrosoft Visual C#Visual C# o MicrosoftMicrosoft Visual BasicVisual Basic.Create a new MicrosoftMicrosoft ASP.NET Web Site using either MicrosoftMicrosoft Visual C#Visual C# or MicrosoftMicrosoft Visual BasicVisual Basic.

    - oppure -- Or -

    Aprire un sito Web ASP.NET esistente e aggiungere un nuovo Web Form.Open an exiting ASP.NET Web Site and add a new Web Form.

  2. Individuare il controllo ScriptManager nel gruppoAJAX Extensions nella finestra Casella degli strumenti e trascinarlo nell'area di progettazione del Web Form.Locate the ScriptManager control in the AJAX Extensions group in the Toolbox window, and drag it to the design surface of the Web form.

    Casella degli strumenti non è visibile, è possibile accedervi scegliendo Casella degli strumenti dal menu Visualizza.If the Toolbox is not visible, you can access it from the View menu by selecting Toolbox.

  3. Individuare il controllo ReportViewer nella Casella degli strumenti e trascinarlo nell'area di progettazione sotto il controllo ScriptManager.Locate the ReportViewer control in the Toolbox and drag it to the design surface below the ScriptManager control.

    Il controllo ReportViewer denominato reportViewer1 verrà aggiunto al form.The ReportViewer control named reportViewer1 is added to the form.

    Dopo l'aggiunta del controllo al form, viene visualizzato lo smart tag ReportViewer Tasks in cui viene richiesto di selezionare un report.After the control is added to the form the ReportViewer Tasks smart tag will appear prompting you to select a report. Se il report da visualizzare è stato distribuito in un server di report, scegliere < dall'elenco a discesa Scegli report.If the report you wish to view has been deployed to a report server select the <Server Report> option from the Choose Report drop-down list. Dopo avere selezionato l'opzione <Server Report>, verranno visualizzate due proprietà aggiuntive, ovvero URL server di report e Percorso report.Once the <Server Report> option is selected two additional properties will appear, Report Server Url and Report Path. L'URL server di report indica l'indirizzo del server di report, mentre Percorso report indica il percorso completo del report di cui si vuole eseguire il rendering.The Report Server Url is the address to the report server and the Report Path is the full path to the report you want to render.

    Per visualizzare un report in modalità locale, selezionare l'opzione Progetta nuovo report per avviare la progettazione del report oppure selezionare un report che fa già parte del progetto esistente.If you want to view a report in local mode select either the Design a new report option to launch the report designer or select a report that is already part of the existing project. Dopo aver selezionato un report, assicurarsi di immettere il nome del file RDLC del report nella proprietà ReportPath del controllo ReportViewer.After you have selected a report, be sure to enter the name of the report RDLC file in the ReportPath property of the ReportViewer control. Questa proprietà viene visualizzata sotto il nodo LocalReport nel riquadro Properties.This property appears under the LocalReport node in the Properties pane.

    È possibile nascondere uno o più elementi sulla barra degli strumenti di ReportViewer quando viene eseguito il rendering del report.You have the option of hiding one or more of the items on the ReportViewer toolbar when the report is rendered. Ad esempio, è possibile nascondere il pulsante di stampa.For example, you can hide the print button. Per nascondere elementi della barra degli strumenti, impostare le proprietà seguenti di ReportViewer su False nel riquadro Proprietà.To hide toolbar items, set the following ReportViewer properties to False in the Properties pane.

Visualizzazione di report in modalità di elaborazione remotaViewing Reports in Remote Processing Mode

Nell'esempio seguente viene illustrato come eseguire il rendering di un report distribuito in un server di report.The following example demonstrates how to render a report that has been deployed to a report server. In questo esempio viene usato il report Sales Order Detail incluso nel progetto di report di esempio AdventureWorks2012AdventureWorks2012.This example uses the Sales Order Detail report that is included with the AdventureWorks2012AdventureWorks2012 sample reports project.

Nell'esempio viene utilizzata l'autenticazione integrata di Windows, pertanto è innanzitutto necessario abilitare la rappresentazione.The example uses integrated Windows Authentication so you first must enable impersonation. A tale scopo, inserire la riga seguente nel file web.config:To do this insert the following line into the web.config file:

<!-- Web.config file. -->  
<identity impersonate="true"/>  

Nota

Per impostazione predefinita, la rappresentazione è disabilitata.Impersonation is disabled by default.

Visualizzazione di report in modalità di elaborazione localeViewing Reports in Local Processing Mode

Nell'esempio seguente viene illustrato come eseguire il rendering di un report che fa parte di un'applicazione Windows e non è stato distribuito in un server di report.The following example demonstrates how to render a report that is part of the Windows application and has not been deployed to a report server.

Per aggiungere il report Sales Order Detail a un sito WebTo add the Sales Order Detail report to a Web Site
  1. Aprire il sito Web a cui verrà aggiunto il report.Open the Web Site that the report will be added to.

  2. Scegliere Aggiungi elemento esistente dal menu Sito Web.From the Website menu, select Add Existing Item.

  3. Passare al percorso di installazione del progetto di report di esempio AdventureWorks.Browse to the location where the AdventureWorks Report Samples project is installed.

    Il percorso predefinito è C:\Programmi\Microsoft SQL Server\100\Samples\Reporting Services\Report Samples\AdventureWorks Sample Reports.The default location is C:\Program Files\Microsoft SQL Server\100\Samples\Reporting Services\Report Samples\AdventureWorks Sample Reports.

  4. Selezionare il file Sales Order Detail.rdl e fare clic sul pulsante Aggiungi.Select the Sales Order Detail.rdl file and click the Add button.

    Il file Sales Order Detail.rdl dovrebbe ora far parte del progetto.The Sales Order Detail.rdl file should now be part of the project.

  5. Fare clic con il pulsante destro del mouse sul file Sales Order Detail.rdl in Esplora soluzioni e selezionare Rinomina.Right-click the Sales Order Detail.rdl file in Solution Explorer and select Rename. Rinominare il report inSales Order Detail.rdlc e premere INVIO.Rename the report to Sales Order Detail.rdlc and press ENTER.

    Se Esplora soluzioni non è visibile, è possibile aprirlo scegliendo Esplora soluzioni dal menu Visualizza.If Solution Explorer is not visible, you can open it from the View menu by selecting Solution Explorer.

    Nell'esempio di codice seguente viene creato un set di dati per i dati dell'ordine di vendita, quindi viene eseguito il rendering del report Sales Order Detail in modalità locale.The following code example will create a dataset for the sales order data and then render the Sales Order Detail report in local mode.
