推荐答案

好，您需要阅读/了解如何使用AjaxControlToolkit控件.

很明显，您尝试使用PasswordStrength控件.使用该控件时，尚未将控件的动作/触发器分配给任何其他控件.
例如，您希望此控件检查TextBoxA中给定的密码是否正确.页面上可以有多个文本框.因此，为了告诉PasswordStrength控件您要检查TextBoxA值的强度，需要将其连接到它.可以使用PasswordStrength控件的属性"TargetControlID"完成此连接.

只需将属性TargetControlID ="txtBoxPassword"放进去，就应该完成了.

在此处查看示例:

Well, you need to read/know on how to use AjaxControlToolkit controls.

It''s very clear that you tried to use a PasswordStrength control. When you were using it, you have not assigned controls action/trigger connected to any other control.
For example, you want that this control checks if the given password in TextBoxA is fine or not. There can be multiple textboxes on the page. Thus, In order to tell PasswordStrength control that you want to check TextBoxA value''s strength, you need to connect that to it. This connection can be done using property ''TargetControlID'' of the PasswordStrength control.

Just put the property TargetControlID="txtBoxPassword" and you should be done.
