与Treeview控件有关的疑问

问题描述

大家好

我正在使用树视图控件将数据库中的值与复选框绑定.
父节点大约有三个孩子.

Hi all

I am using a tree-view control to bind the values from database with check box.
Nearly three child are there for parent node.like

Parent1 
  child1
    child2
      child3
Parent2
   child1
     child2
        child3

我可以绑定来自3个表的数据，它们都工作正常.我想要一种设施，当父节点检查其所有对应的子节点时会自动对其进行检查.如果我单击父节点1，则对子123进行检查.如果我检查child1，child2和child3会得到检查.如果我检查child 2，则会检查所有child3项目.该怎么做?

在此先感谢
