ObjectDataSource.Constructor Property

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

Namespace: DevExpress.DataAccess.ObjectBinding

Assembly: DevExpress.DataAccess.v22.2.dll

NuGet Package: DevExpress.DataAccess

Declaration

[DefaultValue(null)]
public ObjectConstructorInfo Constructor { get; set; }

Property Value

Type Default Description
ObjectConstructorInfo null

An ObjectConstructorInfo value.

Remarks

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.

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).
