Why we do provide SSRS shared/embedded DataSource credential information in .NET WebForms ReportViewer?

Reporting Service information retrieval limitation

RDL reports have limitations to retrieve a password from the SQL Reporting Service (SSRS) due to security reasons. Therefore, the credentials are provided when the DataSource credentials are saved in the Reporting Server for the shared or embedded DataSources.

The following code provides information on SSRS shared/embedded DataSource credentials.

JS, ASP, LSHTML and ASP.NET MVC

      public void OnInitReportOptions(ReportViewerOptions reportOptions)
        {
            reportOptions.ReportModel.DataSourceCredentials.Add(new DataSourceCredentials("datasourcename", "username", "password"));
        }

WPF, WinRT and SilverLight

this.ReportViewer.ReportLoaded += (sen, arg) =>
                    {
                        List<DataSourceCredentials> crdentials = new List<DataSourceCredentials>();
                        foreach (var dataSource in ReportViewer.GetDataSources())
                        {
                            DataSourceCredentials credn = new DataSourceCredentials();
                            credn.Name = dataSource.Name;
                            credn.UserId = " username ";
                            credn.Password = " password ";
                            crdentials.Add(credn);
                        }
                        this.ReportViewer.SetDataSourceCredentials(crdentials);
                    };

Note:

A new version of Essential Studio for ASP.NET is available. Versions prior to the release of Essential Studio 2014, Volume 2 will now be referred to as a classic versions.The new ASP.NET suite is powered by Essential Studio for JavaScript providing client-side rendering of HTML 5-JavaScript controls, offering better performance, and better support for touch interactivity. The new version includes all the features of the old version, so migration is easy.

The Classic controls can be used in existing projects; however, if you are starting a new project, we recommend using the latest version of Essential Studio for ASP.NET. Although Syncfusion will continue to support all Classic Versions, we are happy to assist you in migrating to the newest edition.
