必需的字段验证器阻止面板显示
[英]Required field validator preventing panel to display
问题描述
我正在使用2个链接按钮（协调器和人员），其中on_Click动作显示相应的面板，要求登录/注册/忘记密码。 如果用户选择了注册/忘记密码，则会弹出一个弹出窗口（使用ModalPopupExtender）以询问信息。 除非并直到我在面板中使用了必需的字段验证器，否则一切运行良好，当用户单击“注册/忘记密码”时该面板会弹出。 如果我使用必需的字段验证器，则我的页面运行良好，并且当我单击任何链接按钮（协调器/工作人员）时，什么都不会发生。 这是aspx代码：
