RenderContent.BeginChange Method

RenderContentBeginChange Method

Begins a change or batch of changes. This returns a reference to the content which you should use to make your 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.
