ObjectDataSource.Constructor Property

Specifies an object that enables an ObjectDataSource to access constructor parameters.

Namespace: DevExpress.DataAccess.ObjectBinding

Assembly: DevExpress.DataAccess.v21.1.dll


public ObjectConstructorInfo Constructor { get; set; }

Property Value

Type Default Description


An ObjectConstructorInfo value.


If it is required that on calling the ObjectDataSource.Fill method, an ObjectDataSource should create an instance of the type specified by its ObjectDataSource.DataSource property, use the Constructor property to specify the required constructor parameters. To assign a constructor without parameters, use the static ObjectConstructorInfo.Default object.

For a code sample, see the following example online: How to programmatically generate ObjectDataSource and map object data source constructor parameters to report parameters.

Set this property to null for the ObjectDataSource to never try to create an object instance (if you need to manually create and assign it, or when binding to a static member).
