IObjectDataSourceValidationService Interface

Allows custom validation of the DevExpress.DataAccess.ObjectBinding.ObjectDataSource data sources before using them in the document.

Namespace:DevExpress.Snap.Services
Assembly:DevExpress.Snap.v17.2.Core.dll

Expanded Syntax

Expanded Remarks

The DevExpress.DataAccess.ObjectBinding.ObjectDataSource can cause an undesired behavior when retrieving its data. This may be unacceptable in certain situations. You can use the SnapControlOptions.DataSourceOptions option to specify whether to prohibit the ObjectDataSource data retrieval, prompt the user or silently load the data. To prompt the user, the default IObjectDataSourceValidationService implementation is called. However, you can implement your own service with a custom Validate method to replace the default service.
