XPServerCollectionSource.ObjectClassInfo Property

Gets a XPClassInfo object that describes the target data table in the data store.

Namespace:DevExpress.Xpo
Assembly:DevExpress.Xpo.v19.1.dll

Expanded Syntax

Property value

Type: XPClassInfo
An XPClassInfo object that describes the target data table in the data store.
The default is null.

Expanded Remarks

The ObjectType and ObjectClassInfo properties provide information that describes the target data table. These properties are synchronized. When initializing the ObjectType property, the ObjectClassInfo property is initialized with a matching object, and vice versa.

Do not change the ObjectType and ObjectClassInfo properties directly in your code. Instead, initialize these properties via the objectClassInfo or objectType parameter of the XPServerCollectionSource's constructor.

See the XPServerCollectionSource topic, for information on how to provide descriptive information on the target data table.

Expanded Example

In the following code, an XPServerCollectionSource object is initialized with a persistent object describing a target "Person.Contact" data table (this table is included in the AdventureWorks database that ships with MS SQL Server).

In the code, the Person_Contact persistent object is declared, and mapped to the "Person.Contact" data table using the PersistentAttribute attribute. It exposes specific public properties that match the data table's fields.

To provide data on the Person_Contact object for the XPServerCollectionSource, first a corresponding XPClassInfo object is obtained. Then it's passed to the XPServerCollectionSource's constructor via an objectClassInfo parameter. This initializes the ObjectClassInfo property.

Expanded Example

The following code shows how to initialize an XPServerCollectionSource object with a typed System.Data.DataTable object.

It's assumed that a project contains a System.Data.DataSet class (AdventureWorksDataSet) which owns the target DataTable (_Person_ContactDataTable). In the code, first a XPClassInfo object corresponding to the data table is created. Then it's passed to the XPServerCollectionSource object's constructor via the objectClassInfo parameter, initializing the ObjectClassInfo property.
