To create a data source that uses a connection to an OLAP cube, create the instance of the DashboardOlapDataSource class and perform the following steps.
Create the OlapConnectionParameters class object and specify the DashboardOlapDataSource.ConnectionString property.
Pass the resulting OlapConnectionParameters object to the DashboardOlapDataSource constructor.
Note
As an alternative, you can add a connection string with required parameters to the application configuration file. Then, assign the connection string name to the DashboardOlapDataSource.ConnectionName property.
- Add the created DashboardOlapDataSource object to the Dashboard.DataSources collection.
Note
For ASP.NET Core Dashboard, OLAP mode supports only XML for Analysis (XMLA) with MSMDPUMP. Set the DashboardOlapDataSource.OlapDataProvider static property to Xmla to specify the XMLA data provider.
Examples
The following example demonstrates how to bind a dashboard to an OLAP cube using DashboardOlapDataSource.
The DashboardOlapDataSource allows you to establish a connection to the OLAP cube by specifying a connection string.
