Remarks
The LocalReport class represents reports that are processed and rendered locally without connecting to a report server. This class is the same object that is used by the ReportViewer control, but it also can be used independently as a nonvisual object that encapsulates the core functionality of the ReportViewer control.
The LocalReport object can open client report definition (RDLC) files from the file system or from embedded resources, or the RDLC file can be supplied to it as a Stream or a TextReader.
The LocalReport object does not have the ability to execute queries or fetch data; instead, data sources must be added to the DataSources collection property.
The LocalReport object supports report parameters, but does not support parameter prompts.
Examples
Legacy Code Example
In the following code example, a LocalReport object is used to load and export a report.
private void button1_Click(object sender, EventArgs e)
{
Microsoft.Reporting.WinForms.LocalReport lr = new Microsoft.Reporting.WinForms.LocalReport();
string deviceInfo =
"<DeviceInfo>" +
"<SimplePageHeaders>True</SimplePageHeaders>" +
"</DeviceInfo>";
lr.ReportPath = @"C:\My Reports\Monthly Sales.rdlc";
lr.DataSources.Add(new ReportDataSource("Sales", GetSalesData()));
byte[] bytes = lr.Render("Excel", deviceInfo, out mimeType,
out encoding, out streamids, out warnings);
using (FileStream fs = = new FileStream(@"c:\My Reports\Monthly Sales.xls", FileMode.Create))
{
fs.Write(bytes, 0, bytes.Length);
}
}
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
Dim warnings As Warning() = Nothing
Dim streamids As String() = Nothing
Dim mimeType As String = Nothing
Dim encoding As String = Nothing
Dim extension As String = Nothing
Dim deviceInfo as string
Dim bytes As Byte()
deviceInfo = "< deviceInfo ><SimplePageHeaders>True</SimplePageHeaders></DeviceInfo>"
bytes = ReportViewer1.LocalReport.Render("Excel", Nothing, _
mimeType,encoding, extension, streamids, warnings)
Dim fs As New FileStream("c:\output.xls", FileMode.Create)
fs.Write(bytes, 0, bytes.Length)
MessageBox.Show("Report exported to output.xls", "Info")
End Sub
