Description

Prevents updating of the list view until the EndUpdate method is called.

Call BeginUpdate before making multiple changes to the list of items. When all changes are complete, call EndUpdate so that the changes can be reflected on screen. BeginUpdate and EndUpdate prevent excessive redraws and speed processing time when new items are added, deleted, or inserted.
