Signals the start of an update operation.

Pascal
procedure BeginUpdate;
C++
__fastcall BeginUpdate();
Description

Call BeginUpdate before starting an operation that makes multiple changes to the named Variants list. After completing all of the changes, call the EndUpdate method to signal the end of the operation.  

Every call to BeginUpdate must be matched by a corresponding call to the EndUpdate method.

Note: TAbstractNamedVariants calls BeginUpdate and EndUpdate internally when performing operations that affect multiple entries in the list.
