PopupMenuBase.BeginUpdate Method

Locks the PopupMenuBase object by preventing visual updates of the object and its elements until the EndUpdate method is called.

Namespace:DevExpress.XtraBars
Assembly:DevExpress.XtraBars.v17.1.dll

Expanded Syntax

Expanded Remarks

The BeginUpdate and EndUpdate methods allow you to avoid flickering while performing batch modifications to the PopupMenuBase's settings. Once the BeginUpdate method has been called, modifying settings of the PopupMenuBase and its elements does not cause an immediate visual update. So, multiple modifications can be made to the object and its elements without a major impact on performance or screen flickering. After all the desired operations have been finished, call the EndUpdate method.

The BeginUpdate and EndUpdate methods use an internal counter to implement the update functionality. The counter's initial value is 0. Visual updates are forbidden if the counter's value is greater than 0, and the updates are enabled if the counter's value is 0. The BeginUpdate method increments the counter. The EndUpdate method decrements the counter. If the counter's new value is 0, an immediate visual update occurs. Each call to BeginUpdate must be paired with a call to EndUpdate. To ensure that EndUpdate is always called even if an exception occurs, use the try...finally statement.
