How to Customize Views and Presenters Corresponding to Wizard Pages

To perform deep customization of the Data Source wizard pages, you can update corresponding views and presenters (Model-View-Presenter design pattern). To learn more about common concepts of the Data Source wizard customization, see Wizard Customization API.

To customize the Data Source wizard used in the WinForms Dashboard Designer, perform the following steps:

Implement the IDataSourceWizardCustomizationService interface. This interface exposes the IDataSourceWizardCustomizationService.CustomizeDataSourceWizard method that accepts the IWizardCustomization<TModel> object (where TModel is DashboardDataSourceModel). To register custom page views and presenters, use the following methods.
After you have implemented IDataSourceWizardCustomizationService, assign the resulting object to the DashboardDesigner.DataSourceWizardCustomizationService property.

To learn about presenters and views specific to the WinForms Designer, see the tables below.

Common Pages

Wizard Page	Page Presenter	Page View Interface	Page View
Select a Data Connection	ChooseConnectionPage	IChooseConnectionPageView	ChooseConnectionPageView
Enter the Data Source Name	DashboardChooseDataSourceNamePage<TModel>	IChooseDataSourceNamePageView	ChooseDataSourceNamePageView
Select the Data Connection Type	DashboardChooseDataProviderPage<TModel>	IChooseDataProviderPageView	DashboardChooseDataProviderPageView

OLAP

Wizard Page	Page Presenter	Page View Interface	Page View
Select a Data Connection	ChooseOlapConnectionPage<TModel>	IChooseConnectionPageView	ChooseConnectionPageView
Configure Connection Parameters	ConfigureOlapParametersPage<TModel>	IConfigureOlapParametersPageView	ConfigureOlapParametersPageView

Extract

Wizard Page	Page Presenter	Page View Interface	Page View
Create a Data Extract	CreateExtractDataSourcePage<TModel>	ICreateExtractDataSourcePageView	CreateExtractDataSourcePageView
Select Data Fields	ChooseExtractFieldsPage<TModel>	IChooseExtractFieldsPageView	ChooseExtractFieldsPageView
Specify Filter Options	ConfigureExtractDataSourcePage<TModel>	IConfigureExtractDataSourcePageView	ConfigureExtractDataSourcePageView
Specify Extract Parameters	ExtractParametersPage<TModel>	IExtractParametersPageView	ExtractParametersPageView
Save Extract to a File	StoreExtractFilePage<TModel>	IStoreExtractFilePageView	StoreExtractFilePageView

Example

The following code snippets show how to remove the Connection type option from the Data Source wizard page that allows end-users to specify OLAP connection parameters. To do this, use the DashboardDesigner.DataSourceWizardCustomizationService property.
