ASP.NET Core Report Viewer / Report Data Sources

Which built-in data sources does the viewer support?

The Bold Reports ASP.NET Core Report Viewer supports the following built-in data source types:

• Microsoft SQL Server and Azure SQL Database
• SQL CE
• Oracle
• OLE DB, ODBC, and XML

Business object data sources

The Bold Reports ASP.NET Core Report Viewer renders RDLC client reports from data objects that implement the IList, DataTable, or DataSet interfaces. To display data in the ASP.NET Core Report Viewer, bind the DataSet, DataTable, or business objects that contain the data you need.

Custom data processing extensions

Bold Reports custom data processing extensions connect to and retrieve your own data sources. Data sources outside the built-in types need a custom extension. The .NET Framework-compatible custom data processing extensions can be created using a data extension interface. With these, you can use additional data sources like MySQL, SQLite, PostgreSQL, MongoDB, and others, or extend a built-in data source.

Embedded and shared data sources

• Secure sources through hidden connection details.
• Load shared data sources that are local or embedded in an application.
• Connect data source with expression-based connection strings.

Embedded and shared data sets

A data set in Bold Reports is the stored query that the ASP.NET Core Report Viewer uses to process report data. It supports displaying shared data sets published on an SSRS Report Server.

• Load the shared data set that is local or embedded in an application.
• Use the shared data set in more than one report.
• Show a report that uses a data set with filters, parameters, and user-defined fields and parameters.
