For a data source that is not built in, you can register a custom data adapter and use it in the WPF designer.

Preparing the data. Read or create the data source, register it in the report dictionary, synchronize the schema, and render with the supplied records.
StiOptions.Services.Databases.Clear();
StiOptions.Services.Databases.Add(new CustomPostgreSQLDatabase());
StiOptions.Services.DataAdapters.Add(new CustomPostgreSQLAdapterService());

var report = new StiReport();
var database = new CustomPostgreSQLDatabase("CustomData1",
    "Server=127.0.0.1; Port=5432; Database=myDataBase; User Id=myUsername; Password=myPassword;");
report.Dictionary.Databases.Add(database);
report.DesignV2WithWpf();
The custom adapter is a small set of classes describing how to connect and read data; once registered in StiOptions.Services, the new source works in the designer and the engine like any built-in one.
In the screenshot below you can see the result of the sample code:
