Indicates the number of calls to BeginUpdate that have not been matched by a call to EndUpdate.

Pascal
property UpdateCount: Integer;
C++
__property int UpdateCount;
Description

TWideStrings uses UpdateCount to keep track of calls to the BeginUpdate and EndUpdate methods. Every time a call is made to BeginUpdate, TWideStrings increments the value of UpdateCount. Every call to EndUpdate causes TWideStrings to decrement UpdateCount. 

When UpdateCount changes from 0 to 1, TWideStrings calls the SetUpdateState method with a parameter of true. When UpdateCount changes from 1 to 0, TStrings calls the SetUpdateState method with a parameter of false. This allows descendant classes to perform optimizations when handling multiple updates.
