Ok, so I've got a template field in a gridview that contains just a simple button...

每当我按一下按钮我得到的错误...
Whenever I click the button I get the error...
Invalid postback or callback argument. Event validation is enabled using
<pages enableEventValidation="true"/> in configuration or <%@ Page
EnableEventValidation="true" %> in a page. For security purposes, this feature
verifies that arguments to postback or callback events originate from the server
control that originally rendered them. If the data is valid and expected, use the
ClientScriptManager.RegisterForEventValidation method in order to register the
postback or callback data for validation.

我可能只是误会，但据我可以告诉他们并不真正帮助我。我如何得到这个去吧，不用设置enableEventValidation =假？
I might just be misunderstanding, but as far as I can tell they don't really help me. How do I get this to go away without setting enableEventValidation="false"?
修改发布的所有code为我的网页。
EDIT Posted all the code for my page.
推荐答案
这个家伙找到了解决类似的问题（向下滚动到约4注释），这是设置唯一ID的为GridView的按钮。
This fellow found a solution to a similar problem (scroll down to about the 4th comment), which was to set unique id's for the GridView buttons.
