This document lists pages included in the Data Source Wizard along with classes defining presenters and page views corresponding to WinForms implementation.

All these pages are also included in the Report Wizard. This topic lists custom implementations of these pages that are specific to the Report Wizard logic.

Wizard Structural Elements

The structural elements of the Data Source Wizard conform to the MVP (model-view-presenter) pattern and are set out in the following namespaces:

• Models

• Views

• Presenters

The following document sections describe presenters and views corresponding to specific Data Source Wizard pages, as well as classes that store intermediate settings of a data source during wizard execution:

Start Pages

Wizard Page	Page Presenter	Page View Interface	Page View
Select a Data Connection	ChooseConnectionPage<TModel>	IChooseConnectionPageView	ChooseConnectionPageView
Select a Data Connection Type	ChooseDataProviderPage<TModel>	IChooseDataProviderPageView	ChooseDataProviderPageView

Connect to a Database

The SqlDataSourceModel class stores intermediate settings of a SQL data source.

Wizard Page	Page Presenter	Page View Interface	Page View
Specify Connection Properties	ConnectionPropertiesPage<TModel>	IConnectionPropertiesPageView	ConnectionPropertiesPageView
Save the Connection String	SaveConnectionPage<TModel>	ISaveConnectionPageView	SaveConnectionPageView

Wizard pages may vary depending on the wizard implementation your application uses.

• The following wizard pages correspond to the default wizard implementation, which allows you to create multiple queries in one wizard run and create master-detail relationships at once:

• The pages listed below correspond to the older wizard implementation where it is only possible to create a single query in one wizard run.
