文件上传...浏览点不了？是怎么回事？

比如，有一个页面，上面有4的FileUpLoad控件，对应着4个Button，如果上传一点文件成功后，所有的FileUpLoad控件的浏览都不能点了，Button却可以点，要刷新页面、或重新打开页面后FileUpLoad的浏览才可以用？这是什么原因啊？求解决

IE下运行，这种情况很少出现，但是也出现过，只是很少出现，
搜狗不能用

测试了一下发现代码没问题啊在我这里上传一个后都还能用

#5

IE可以用，极少数情况下不能用，用搜狗完成不能用个

#6

搜狗完全不能用

#7

this.Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "dd",
"<script>"<script>alert('上传成功');location.href='FileUpLoad.aspx?js=" + new Random().Next() + "';</script>");

所有的提示都用这种形式

#8

当你点击一个上传成功后触发后台事件之后页面也就会刷新你所记录的那个信息就不起作用了
