Remarks

The DashboardXpoDataSource allows you to obtain data that XPO (eXpress Persistent Object) retrieves from a data source.

Runtime

Create a DashboardXpoDataSource object and use the ConnectionStringName property to specify the name of the connection string defined in the application configuration file.
Pass the persistent object type to the SetEntityType method.

The code sample below illustrates how to connect to the XPO data source.

C#
VB.NET

using DevExpress.DashboardCommon;
// ...
public static DashboardXpoDataSource CreateXpoDataSource()
{
    DashboardXpoDataSource dataSource = new DashboardXpoDataSource()
    {
        ConnectionStringName = "northwind"
    };
    dataSource.SetEntityType(typeof(nwind.Customers));
    return dataSource;
}

Imports DevExpress.DashboardCommon

Public Shared Function CreateXpoDataSource() As DashboardXpoDataSource
  Dim dataSource As New DashboardXpoDataSource() With {.ConnectionStringName = "northwind"}
  dataSource.SetEntityType(GetType(nwind.Customers))
  Return dataSource
