public static void RegisterJsonDataConnectionProviderFactory<T>()
    where T : IJsonDataConnectionProviderFactory

Public Shared Sub RegisterJsonDataConnectionProviderFactory(Of T As IJsonDataConnectionProviderFactory)

Type Parameters

Name	Description
T

A type that implements the DevExpress.DataAccess.Web.IJsonDataConnectionProviderFactory interface.

Remarks

Call this method on application startup if you use the DefaultReportDesignerContainer.RegisterDataSourceWizardJsonConnectionStorage) method to register a custom JSON connection storage and specify the method’s parameter to true.

In this situation, the Document Viewer calls the IJsonDataConnectionProviderFactory.Create method to obtain an object with the IJsonDataConnectionProviderService interface that provides the JSON connection string.

The following code snippet illustrates how to use the RegisterJsonDataConnectionProviderFactory method:
