Walkthrough: Printing a Local Report without Preview 

This walkthrough shows how to programmatically print a report without viewing it, using the LocalReport object and the CreateStreamCallback callback function.

You must have access to the sample report and data source. For more information, see Sample Data and Report for Print Walkthrough.

Perform the following steps to create a Microsoft Visual Studio Console application project.

  1. On the File menu, point to New, and then select Project.

  2. In the Project Types pane, choose Visual C# or Visual Basic and Windows.

  3. In the Templates pane, choose Console Application to create a Microsoft Console application.

  4. In the Name box, type the name of the project: PrintLocalReport.

  5. In the Location box, enter the directory in which you want to save your project, or click Browse to navigate to it. The project opens with the Code window showing the Program code file.

  1. From the Project menu, select Add Reference. The Add Reference dialog box will appear.

  2. From the list box displayed on the .NET tab, select System.Drawing, System.Windows.Forms, and Microsoft.Reporting.Winforms.

  1. From the Project menu, select Add Existing Item. The Add Existing Item dialog box will appear.

  2. Navigate to the folder where you saved report.rdlc and data.xml. Select both files.

  3. Click Add. The two files appear in Solution Explorer as part of the project.

  1. The Program code file should already be open for editing. If it is not, double-click on the Program.cs or Module1.vb file in the Solution Explorer window.

  2. Replace existing code in the Program file with the following code of your programming language choice.

    For Visual C#, use the following code.

  1. On the Build menu, click on Build Solution to build the application. As part of the build process, the report is compiled and any errors found (such as a syntax error in an expression used in the report) are added to the Task List.

  2. Press F5 to run the application.
