Remarks
The EntityServerModeDataSource component allows you to bind the ASPxCardView, ASPxGridView, ASPxVerticalGrid, ASPxComboBox and ASPxPivotGrid controls to a data source via the Entity Framework, and enable the database server mode. To do this, follow the steps listed below:
- use the EntityServerModeDataSource.ContextTypeName property to specify the type of objects retrieved from a data source;
- use the EntityServerModeDataSource.TableName property to specify the table name;
- bind the ASPxGridView to the EntityServerModeDataSource component.
Important
To use the Server Mode with Entity Framework 6+, it is necessary to use special options on the application startup. To learn more, see the Knowledge Base Article: Is it possible to use the Entity Framework 6 and Server Mode together.
