树形结构数据输入输出控件的设计与实现

摘要

To solve the problem that a tree structure data information can not be inputted integrally by the existing tree structure data input and output controls, the method of composite controls is presented. The composite control is made of improved existing tree structure data input and output controls, and integrated with other controls. The composite control integrated improved existing tree structure data input and output controls with other controls. This method analysis the form of tree structure data in the database, the existing tree structure data input and output controls are designed and packaged respectively, and a user-defined single table control and a multi-table tree structure data output control are achieved, then based on the self-defined tree structure data output control, and combined with other controls, the tree structure data input control is designed combining with other controls. The control is a data- sensitive control, and after packaged, data' s display simply fills out the custom properties. By design designing case of a spare parts cataloging, the validity of the presented method is demonstrated.%为解决现有树形结构数据输入输出控件都不能很好地输入一个树形数据完整信息的问题,提出了对现有树形结构数据输入输出控件进行改进并与其它控件组合成复合控件的方法.该方法分析了树形结构数据在数据库中的存在形式,分别设计并封装了现有树形结构数据输入输出控件,实现了自定义单表和多表树形结构数据输出控件,然后在自定义输出控件的基础上结合其它控件设计了单表和多表树形结构数据输入控件.该控件是数据敏感的,封装后数据的显示只需填写相关的自定义属性.并通过备件编目实例验证了该方法的有效性.
