Remarks
A custom connection strings provider (that implements the IDataSourceWizardConnectionStringsProvider interface) strictly defines which data connections will be available in the Web Report Designer.
When the overrideWebConfigConnections parameter value is set to true, the registered data connections will override those defined in the application’s Web.config file and data sources created using the SQL Data Source Wizard will store only the connection name (the connection parameters will be discarded).
In this case, the connections defined in the registered connection strings provider will be displayed on editing any data sources available in the Web Report Designer. The following data sources are possible.
- New data sources created using the SQL Data Source Wizard.
- Report data sources restored along with a report layout.
- Registered data sources in the Web Report Designer.
The following code sample shows how to register the custom connection strings provider by calling the RegisterDataSourceWizardConnectionStringsProvider<T> method on application start.
using DevExpress.XtraReports.Web.ReportDesigner;
using System;
// ...
public class Global_asax : System.Web.HttpApplication {
void Application_Start(object sender, EventArgs e) {
// ...
// Register the custom connection strings provider.
DefaultReportDesignerContainer.RegisterDataSourceWizardConnectionStringsProvider<MyDataSourceWizardConnectionStringsProvider>(true);
}
// ...
}
