#Example
The following example demonstrates how to delay the loading of the DelayedAttachment property and improve property value update performance, by enabling the DelayedAttribute.UpdateModifiedOnly property.
Note
This solution uses the XPDelayed
using DevExpress.Xpo;
public class Customer : XPObject {
// ...
private XPDelayedProperty document = new XPDelayedProperty();
// Improve update performance for the property's value
// by passing true as the attribute's
// updateModifiedOnly parameter.
[Delayed(nameof(document), true)]
public Byte[] DelayedAttachment {
get { return (Byte[])document.Value; }
set { document.Value = value; }
}
}
