IPersistentObjectStorage<T>.IsUpdateLocked Property

Gets whether the storage has been locked for updating.

Namespace:DevExpress.XtraScheduler
Assembly:DevExpress.XtraScheduler.v17.1.Core.dll

Expanded Syntax

Property value

Type: Boolean
True if the storage is locked; otherwise, false.

Expanded Remarks

The BeginUpdate and EndUpdate methods use an internal counter to implement 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 corresponding call to EndUpdate afterwards, or it's not called because an exception occurred, the storage will no longer be updated. To ensure that EndUpdate is always called even if an exception occurs, use the try...finally statement.
