Viewer Sidebar

The Viewer sidebar appears on the left of the Viewer control when you click the Toggle sidebar button in the toolbar. By default, this sidebar shows the Thumbnails and Search Results panes. The additional Document map and Parameters also appear in this sidebar. You can toggle between any of the viewer panes by clicking the buttons for each pane at the bottom of the sidebar.

Thumbnails pane

The Thumbnails pane appears by default in the sidebar when you click the Toggle sidebar button in the toolbar.

This pane is composed of a thumbnail view of all the pages in a report. Click any thumbnail to navigate directly to the selected report page. You can also modify the size of the thumbnail when you click (+) or (-) button to zoom in and zoom out.

Search results pane

The Search pane is the other default pane besides Thumbnails that appears in the sidebar when you click the Toggle sidebar button. This pane lets you enter a word or phrase from which to search within the report.

To search in a report:

  • Enter the word or phrase in the search field.
  • Under Use these additional criteria, you may optionally choose to search for the whole word or match the case of the search string while searching in the report.
  • Click the Search button to see the results appear in the Find results list.
  • Click an item in the list to jump to that item in the report and highlight it.

To start a new search or clear the current search results, click the Clear button under the Find results list.

Document map pane

The Documents map pane is enabled for reports where the Label property or the Document map label is set. This pane displays each value for the text box, group, or sub report that you label, and you can click them to navigate to the corresponding area of the report in the Viewer.

If a report does not have the Label property or Document map label set, the Documents map pane does not appear in the sidebar.

Parameters pane

The Viewer allows you to view reports with parameters. In the toolbar, click the Toggle sidebar button to open the Viewer sidebar and if your report contains parameters, the Parameters pane shows up automatically.

  1. In the Parameters pane, you are prompted to enter a value by which to filter the data to display.
  2. Enter a value or set of values and click View report, to filter the report data and display the report.

If a report does not have parameters, the Parameters pane does not appear in the sidebar.

Display Report Output in the Viewer

The following code examples demonstrate how you can display the report output in the Viewer.

  1. In a Visual Studio Windows Forms application, from the Visual Studio toolbox, drag the Viewer control onto your Windows Form.
  2. Set the viewer's Dock property to Fill to show the complete Viewer control on the Form.
  3. Double-click the title bar of the Form to create an event-handling method for the Form_Load event.
  4. In the Form_Load event, add code like the following to run the report and display it in the viewer. Each of these code snippets presumes a report in the project of the type indicated with the default name. (If you have renamed your report, you need to rename it in the code as well)

    To write the code in Visual Basic.NET

    The following example demonstrates how you display a page report in the Viewer control.

    Visual Basic. NET code. Paste INSIDE the Form_Load event.
    Copy Code 
    Dim file_name As String = "..\..\PageReport1.rdlx"
Dim pageReport As New GrapeCity.ActiveReports.PageReport(New System.IO.FileInfo(file_name))
Dim pageDocument As New GrapeCity.ActiveReports.Document.PageDocument(pageReport)
Viewer1.LoadDocument(pageDocument)

    The following example demonstrates how you display a RDL Report in the Viewer control.

    Visual Basic. NET code. Paste INSIDE the Form_Load event.

viewer1.LoadDocument(sectionReport);

    The following example demonstrates how you can display a section report (xml-based) in the Viewer control.

    C# code. Paste INSIDE the Form_Load event
    Copy Code 
    GrapeCity.ActiveReports.SectionReport sectionReport = new GrapeCity.ActiveReports.SectionReport();
System.Xml.XmlTextReader xtr = new System.Xml.XmlTextReader(@"..\..\SectionReport1.rpx");
sectionReport.LoadLayout(xtr);
xtr.Close();
viewer1.LoadDocument(sectionReport);

Additional Features

Following is an introduction to the additional capabilities of the Viewer to guide you on using it effectively:

Split windows

  1. Run your viewer project.
  2. Click above the vertical scrollbar to grab the splitter control and drag downward.
  3. With the viewer split into two sections, you can easily compare report pages.

Advanced Printing Options

Viewer provides advanced printing options that allow you to control the report page layout and watermark settings through the Page Setup dialog. In this dialog, you can also preview the report as it would appear with each print setting. See Advanced Print Options for further details.

You can also set the PrintingSettings property of the Viewer to directly print without displaying a dialog or to switch from a ActiveReports print dialog to a .NET Framework standard print dialog (System.Windows.Forms.PrintDialog) on clicking the Print button on the Viewer toolbar. You can set the PrintingSettings property of the Viewer control from the Properties window.


PrintingSettings property provides the following options:

PrintingSettings Options Description
ShowPrintDialog

Displays a dialog in which the user can set the printer options before printing.
ShowPrintProgressDialog Displays a print progress dialog, in which the user can cancel the printing job.
UsePrintingThread Specifies whether printing should be performed for individual threads or not.
UseStandardDialog Specifies whether to use the .NET Framework standard print dialog (System.Windows.Forms.PrintDialog) while printing the document (section or page).

 

Exporting

Use the Export Filters to export a page or a section report to different formats directly from the Viewer. After you load the document in the Viewer, you can use a sample code like the following which shows one overload of the Export method with a PDF export filter. This code creates an outputPDF.pdf file in the bin\debug folder of your project.

To write the code in Visual Basic.NET

Visual Basic. NET code. Paste INSIDE an event like Button_Click event.
Copy Code 
Dim PDFEx As New GrapeCity.ActiveReports.Export.Pdf.Section.PdfExport
Viewer1.Export(PDFEx, New FileInfo(Application.StartupPath + "\outputPDF.pdf"))

To write the code in C#

C# code. Paste INSIDE an event like Button_Click event.
Copy Code 
GrapeCity.ActiveReports.Export.Pdf.Section.PdfExport PDFEx = new GrapeCity.ActiveReports.Export.Pdf.Section.PdfExport();
viewer1.Export(PDFEx, new System.IO.FileInfo (Application.StartupPath + "\\outputPDF.pdf" ));
Note: Make sure that you add a reference to the required export assembly in your project before setting the export filter in code. See Export Filters further details.

Annotations Toolbar

You can use annotations when working with a report in the Viewer and add notes, special instructions or images directly to the reports.

Annotations are added via the Viewer's toolbar, which is hidden by default. You can make the Annotations toolbar available by setting the AnnotationDropDownVisible property to true in the viewer's properties grid.

Annotation Name Description
