Remarks

Use the DataSourceTypes property to specify the data source types that should be displayed on the "Select the data source type" page of the Data Source Wizard.

Note

Take into account the following limitations:

• The Data Federation data source is available in the Data Source Wizard only if a snap report contains at least one data source.
• The DevExpress Snap uses the open-source Newtonsoft.Json library to provide JSON data at runtime. We recommend you to install the required NuGet package to use this data source type.

The following example demonstrates how to display only the Entity Framework and Excel File items in the Data Source Wizard.

C#

snapControl1.Options.DataSourceWizardOptions.DataSourceTypes = DataSourceTypes.EntityFramework | DataSourceTypes.Excel;

VB.NET

snapControl1.Options.DataSourceWizardOptions.DataSourceTypes = DataSourceTypes.EntityFramework Or DataSourceTypes.Excel

The image below shows the result of the code.
