Remarks
This property is accessible using the SpreadsheetControl.Options.DataSourceLoading.CustomAssemblyBehavior notation.
The SpreadsheetCustomAssemblyBehavior.Prompt value raises the SpreadsheetControl.CustomAssemblyLoading event and calls the ICustomAssemblyLoadingNotificationService.RequestApproval method of the SpreadsheetControl service to determine whether to load the Entity Framework data context from a custom assembly.
Tip
Use the SpreadsheetDataSourceWizardOptions.CustomAssemblyBehavior property to specify whether the Data Source Wizard can load a custom assembly containing the Entity Framework data context.
