The invention provides a tree view node loading display method for an information management system. The method comprises the following steps: only loading the key properties of all child nodes of the node when expanding a node in a tree view; determining all the nodes which belong to a current display area in the tree view; acquiring the content according to the key properties of all the nodes in the current display area; and displaying all the nodes and the content in the current display area. The invention solves the performance problem in the prior art when large data and quantity data inthe tree view is loaded and displayed, and the speed of loading and displaying the nodes is accelerated.
Description
Tree View Node Loading and Displaying Method for Management Information System technical field The invention relates to the field of numerical control, in particular to a method for loading and displaying tree view nodes used in a management information system. Background technique Enterprise management software for discrete manufacturing such as CAPP (Computer Aided Process Planning, computer-aided process design), EDM (Electronic Document Management), PDM (Product Data Management, product data management), PLM (Product Lifecycle Management, product life cycle management), ERP (Enterprise Resource Planning, enterprise resource Planning) are typical MIS (ManagerInformationSystem, management information system), is also a typical database application system, mainly processing the data information in the database. Such systems usually have performance problems caused by one-time browsing and loading of large amounts of data / massive "data", such as: the "Tree View (TreeView)"...
