Remarks

The DataSource objects are used to supply dashboards with data.

There are two primary approaches for creating data sources.

1. Provide your data as a collection of records. This collection must implement the IEnumerable or IListSource interface. To assign this collection to a data source, pass it to the DataSource constructor or assign it to the DataSource.Data property. The examples below demonstrate this approach.

2. Create a data provider represented by the SqlDataProvider or OlapDataProvider classes. When creating a data provider, you can specify the connection parameters used to establish a connection to data. Then, pass the created provider to the DataSource constructor. The examples below demonstrate this approach.

   How to: Bind a Dashboard to an OLAP Cube using DashboardOlapDataSource

Data-aware dashboard items have the DataDashboardItem.DataSource property that specifies a data source to which this item is actually bound.

A Dashboard also exposes the Dashboard.DataSources collection that contains data sources displayed within the Data Source Browser in the DashboardDesigner, so that end-users can use them when designing a dashboard.
