Specifies how to load master form data found in the repository.
public AutoFormsEngineMasterFormLoadType MasterFormLoadType { get; set; }
The load type for master form data
This property is used to control the amount of memory used to hold master form data while maintaining its speed. The AutoFormsEngine performs the fastest when all master form data are loaded in memory. If the repository contains too many master forms to be loaded in memory, then either master form data is loaded on demand or stored in cache as a tradeoff between speed or memory. Notice that the cache option works only when FullTextSearchManager
is set, otherwise it will work as load on demand option.
