Namespace: DevExpress.XtraScheduler
Assembly: DevExpress.XtraScheduler.v19.1.Core.dll
Declaration
Property Value
| Type | Description |
|---|---|
| Boolean | true if the persistent object is locked; otherwise, false. |
Remarks
The PersistentObject.BeginUpdate and PersistentObject.EndUpdate methods use an internal counter to implement the appropriate functionality. The counter’s initial value is 0. The BeginUpdate method increments the counter. EndUpdate decrements the counter and if its new value is zero, change notifications are enabled. Note that each call to BeginUpdate must be paired with a call to EndUpdate. If a call to BeginUpdate is made but without a call to EndUpdate afterwards or it’s not called because an exception occurred, the persistent object will no longer be updated. To ensure that EndUpdate is always called even if an exception occurs, use a try…finally statement.
