Usare il controllo WinForms ReportViewer
Per visualizzare i report distribuiti in un server di report o report presenti nel file system locale, usare il controllo WinForms ReportViewer per eseguirne il rendering in un'applicazione Windows.
Aggiungere il controllo ReportViewer a un'applicazione Windows
Creare una nuova applicazione Windows usando Microsoft C# o Microsoft Visual Basic.
oppure
Aprire un progetto Applicazione Windows esistente e aggiungere un nuovo form.
Individuare il controllo ReportViewer nella casella degli strumenti. Se la casella degli strumenti non è visibile, è possibile accedervi dal menu Visualizza selezionando Casella degli strumenti.
Trascinare il controllo ReportViewer nell'area di progettazione di Windows Form.
Un controllo ReportViewer denominato reportViewer1 viene aggiunto al form.
Dopo l'aggiunta del controllo al form, viene visualizzato lo smart tag Attività di ReportViewer che richiede di selezionare un report.
Se il report che si desidera visualizzare viene distribuito in un server di report, selezionare l'opzione <Report> server dall'elenco a discesa Scegli report . Dopo aver selezionato l'opzione <Report> server, vengono visualizzate altre due proprietà: URL del server di report e Percorso report. URL server di report è l'indirizzo del server di report e Percorso report è il percorso completo del report di cui eseguire il rendering.
Se il report da visualizzare è 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.
Visualizzazione di report in modalità di elaborazione remota
Nell'esempio seguente viene illustrato come eseguire il rendering di un report distribuito in un server di report usando il controllo ReportViewer WinForms. In questo esempio viene usato il report Sales Order Detail incluso nel progetto di report di esempio AdventureWorks2022.
C#
public partial class Form1 : Form
{
private void Form1_Load(object sender, EventArgs e)
{
// Set the processing mode for the ReportViewer to Remote
reportViewer1.ProcessingMode = ProcessingMode.Remote;
ServerReport serverReport = reportViewer1.ServerReport;
// Get a reference to the default credentials
System.Net.ICredentials credentials =
System.Net.CredentialCache.DefaultCredentials;
// Get a reference to the report server credentials
ReportServerCredentials rsCredentials =
serverReport.ReportServerCredentials;
// Set the credentials for the server report
rsCredentials.NetworkCredentials = credentials;
// Set the report server URL and report path
serverReport.ReportServerUrl =
new Uri("https:// <Server Name>/reportserver");
serverReport.ReportPath =
"/AdventureWorks Sample Reports/Sales Order Detail";
// Create the sales order number report parameter
ReportParameter salesOrderNumber = new ReportParameter();
salesOrderNumber.Name = "SalesOrderNumber";
salesOrderNumber.Values.Add("SO43661");
// Set the report parameters for the report
reportViewer1.ServerReport.SetParameters(
new ReportParameter[] { salesOrderNumber });
// Refresh the report
reportViewer1.RefreshReport();
}
}
VB.NET
Imports Microsoft.Reporting.WinForms
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles MyBase.Load
'Set the processing mode for the ReportViewer to Remote

Dim serverReport As ServerReport

'Create the sales order number report parameter
Dim salesOrderNumber As New ReportParameter()
salesOrderNumber.Name = "SalesOrderNumber"
salesOrderNumber.Values.Add("SO43661")
'Set the report parameters for the report
Dim parameters() As ReportParameter = {salesOrderNumber}
serverReport.SetParameters(parameters)
'Refresh the report
reportViewer1.RefreshReport()
End Sub
End Class
Visualizzare i report in modalità di elaborazione locale
Nell'esempio seguente viene illustrato come eseguire il rendering di un report che fa parte dell'applicazione Windows e non viene distribuito in un server di report.
Per aggiungere il report Sales Order Detail a un'applicazione Windows
Aprire il progetto Windows a cui verrà aggiunto il report.
Dal menu Progetto selezionareAdd Existing Item(Aggiungi elemento esistente).
Passare al percorso di installazione del progetto dei report di esempio di
AdventureWorks2022.Scaricare gli esempi di report, passare a AdventureWorks Report Samples (Esempi di report AdventureWorks)
Selezionare il file Sales Order Detail.rdl e selezionare il pulsante Aggiungi .
Il file Sales Order Detail.rdl dovrebbe ora far parte del progetto.
Fare clic con il pulsante destro del mouse sul file Sales Order Detail.rdl in Esplora soluzioni e selezionare Rinomina. Rinominare il report in Sales Order Detail.rdlc e premere INVIO.
Se Esplora soluzioni non è visibile, è possibile aprirlo dal menu Visualizza selezionando Esplora soluzioni.
Nota
La modifica dell'estensione di file da rdl in rdlc consente di modificare il report usando Progettazione report per Microsoft Visual Studio 2005.
Dopo aver rinominato il report, selezionare il file e individuare il Finestra Proprietà. Modificare la proprietà Copia nella directory di output in Copia se più recente.
Se la finestra Proprietà non è visibile, è possibile aprirla dal menu Visualizza selezionando Finestra Proprietà.
Nell'esempio di codice seguente viene creato un set di dati per i dati dell'ordine di vendita e quindi viene eseguito il rendering del report Sales Order Detail in modalità locale.
C#
public partial class Form1 : Form
{
private void Form1_Load(object sender, EventArgs e)
{
// Set the processing mode for the ReportViewer to Local
reportViewer1.ProcessingMode = ProcessingMode.Local;
LocalReport localReport = reportViewer1.LocalReport;
localReport.ReportPath = "Sales Order Detail.rdlc";
DataSet dataset = new DataSet("Sales Order Detail");
string salesOrderNumber = "SO43661";
// Get the sales order data
GetSalesOrderData(salesOrderNumber, ref dataset);
// Create a report data source for the sales order data
ReportDataSource dsSalesOrder = new ReportDataSource();
dsSalesOrder.Name = "SalesOrder";
dsSalesOrder.Value = dataset.Tables["SalesOrder"];
localReport.DataSources.Add(dsSalesOrder);
// Get the sales order detail data
GetSalesOrderDetailData(salesOrderNumber, ref dataset);
// Create a report data source for the sales order detail
// data
ReportDataSource dsSalesOrderDetail =
new ReportDataSource();
dsSalesOrderDetail.Name = "SalesOrderDetail";
dsSalesOrderDetail.Value =
dataset.Tables["SalesOrderDetail"];
localReport.DataSources.Add(dsSalesOrderDetail);
// Create a report parameter for the sales order number
ReportParameter rpSalesOrderNumber = new ReportParameter();
rpSalesOrderNumber.Name = "SalesOrderNumber";
rpSalesOrderNumber.Values.Add("SO43661");
// Set the report parameters for the report
localReport.SetParameters(
new ReportParameter[] { rpSalesOrderNumber });
// Refresh the report
reportViewer1.RefreshReport();
