asp.net验证控制禁止按钮单击事件

好的,两天后仍然会出现问题。 我有一个asp.net表单,包含几个文本字段,一个下拉列表和一个注册按钮。

问题: 当我将客户端验证器应用于文本字段并下拉时,按钮单击事件被禁止(对于页面上的所有按钮;不仅用于提交按钮,还用于从MasterPage继承的全局导航按钮)。某些字段有多个验证器(例如必填字段和reg ex)。

当我注释掉任何验证器时,所有按钮的点击事件都按预期运行。

我似乎是一个疯狂的工作,插入一个额外的不需要的'虚拟'验证器只是为了评论,但它似乎只适用于n-1验证器(即无论我在页面上有多少验证器,它只会与任何一个人合作评论出来)。

网上有链接到aspalliance.com上关于这个确切主题的文章但遗憾的是,链接已被破坏。有人可以建议一个解决方案吗?

谢谢,Daf。

对我而言,您似乎需要使用验证组将控件与提交按钮绑定。 http://weblogs.asp.net/scottgu/archive/2004/10/24/246945.aspx

或确保所有其他不应触发验证的按钮都将CausesValidation属性设置为False。
