Description
Each time you modify the collection of items displayed in a component, for example, add new items or delete existing items, the component that holds this collection is repainted. You can use the BeginUpdate method before making changes to the collection in order to suspend repainting the component until the changes are complete. To resume painting the component, call the EndUpdate method after the changes are complete. This approach optimizes performance and can prevent the component from blinking when items are added or removed.
