This article explains how to deploy SQL reports programmatically into Reporting Server 2005, using Web Services exposed by SQL Reporting Services 2005.

Introduction

Most of the time, it is acceptable for customers to deploy reports manually via the Visual Studio Report Manager. But sometimes, there may be a hard rule that "anything deployable, for instance, WinForms apps, WebForms apps, or SSRS reports, etc. has to be deployed via MSI.

This sample basically has a config file to collect information like where the data source for a report should be created, and what its name should be, and the user name and password that should be used in the data source. Making all this information dynamic is important because one often publishes a report and its data source points to a different location on a production server than on the machine it was originally created.

Using the code

Once the setup information is collected from the app.config, the method Install starts deploying the report on to the server.

Source Code:

Steps to be taken care of:

  1. Add a Web reference to the web service exposed by the SSRS (SQL Reporting Service 2005).
  2. Set the config settings [information such as report name, database connection etc.].
