CHAPTER 9 RENDERING REPORTS FROM .NET APPLICATIONS
Credential Parameters
If, in previous versions of Reporting Services, you were using credential parameters to pass datasource
connection information, you will have to modify these reports to upgrade them to a SSRS 2012 server.
The credential parameters that passed username and password information to a report server for
rendering were stored in plain text in the browser cache. This was very insecure and this set of
parameters has been removed from SSRS 2012.
Report Viewer Web Part Commands
Report web part viewer commands are prefixed with rv: and are used to target the web part used to view
reports in SharePoint mode. You can use these parameters to control how the report and its controls are
displayed from the web part. You can also use these parameters to control how the report will be
rendered. You can see these parameters in Table 9.4.
