asp.net表格有四个下拉列表 [英] asp.net form with four dropdownlist

问题描述

当我选择任何一个例如dropdownlist1例如india时，我们在web表单和一个gridview中选择四个下拉列表，然后数据将直接显示在gridview中。我怎么能为此编码...有四个表国家，州，城市和地区..如果我在第二个下拉列表中选择国家显示状态..发送该代码帮助我....

解决方案

您应该对所有dropdownlis使用SelectedIndexChanged事件。您应该在Country的下拉列表SelectedIndexChanged事件上编写gridview绑定代码和状态下拉列表绑定代码。
