推荐答案
尊敬的专家2天我终于弄清楚后，为什么我的页面不回发。之后我试图用java脚本手动回来后我的按钮，我失败了。我试图跟踪剧本，我发现这个错误与萤火虫：
Dear Expert After 2 day finally i figure out why my page doesn't post back. after i tried to post back my button manually with java script and i failed. i tried to trace the script and i found this Error with firebug:
TypeError: theForm.submit is not a function
theForm.submit();
当我谷歌，我发现我在母版使用id =提交有一个按钮，并为提交不是一个函数意味着你在你的命名提交按钮或一些其他元素提交。重命名按钮btnSubmit，将您的通话将神奇的工作。
when i google it i found i have a button in my MasterPage with id="Submit" and as "submit is not a function" means that you named your submit button or some other element submit. Rename the button to btnSubmit and your call will magically work.
在名称的按钮提交，你重写表单的提交（）函数。
When you name the button submit, you override the submit() function on the form.
所以这个问题解决。感谢所有。
So This Problem Resolved. Thanks to all.
