RenderContentBeginChange Method |
Begins a change or batch of changes. It may also make a
copy of the content state allowing
EndChange to send an
event with the old and new contents. Calls to this method are counted;
you must call EndChange() once for every call to BeginChange().
Note:
If Changed() was called between the calls to BeginChange() and
EndChange(), the last call to EndChange() may cause the ContentChanged
event to be sent.
