Updates the specified object in the current Object Space with data from the data source.

Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v23.2.dll

NuGet Package: DevExpress.ExpressApp

Declaration

C#

public override object ReloadObject(
    object obj
)

Public Overrides Function ReloadObject(
    obj As Object
) As Object

Parameters

Name	Type	Description
obj	Object	An object to be reloaded from the data source.

Returns

Type	Description
Object	The reloaded object.

Remarks

If the specified object is a new object, the ReloadObject method does nothing. To ensure that the object is not a new object, use the IsNewObject(Object) method.

If the specified object does not belong to the current Object Space, the ReloadObject method retrieves this object to the current Object Space, and then reloads its state.

A CannotReloadPurgedObjectException is thrown if the specified persistent object is deleted from the data store.
