推荐答案
您需要为不同的用户创建角色

You need to create roles for different users

当您点击按钮时，页面加载。但是您已在母版页中的IsPostBack中编写了这些代码。没有IsPostBack中的代码并测试。
放入调试器在测试时知道事件是如何循环的。
When you click on a Button,Page Loads. But you have written those codes inIsPostBackin Master Page. Don't have the code insideIsPostBackand test.
Putdebuggerswhile testing to know how the events cycles.
