|Navigation: ABC Library Reference > BrowseClass > BrowseClass Properties >====== ChangeControl (browse change/update control number) ======
The ChangeControl property contains the number of the browse's change/update control. This is typically the value of the Change BUTTON's field equate. The BrowseClass methods use this value to enable and disable the control when appropriate, to post events to the control, to map change behavior to corresponding popup menu choices, etc.
The BrowseClass.Init method does not initialize the ChangeControl property. You should initialize the ChangeControl property after the BrowseClass.Init method is called. See the Conceptual Example.
