解决方案
您是否已在源文件中添加了两个标签.
每个aspx只允许使用一个标签.
删除多余的标签，然后尝试. .aspx)删除当前网页的表单标签，即删除
< 表单 runat =" 服务器" < /form >
谢谢，
hemant
为什么在这里添加了form标签?您正在使用Master页面！不需要form标签.只需删除它即可.

Have u added two tag in your source file.
Only one Tag is allowed per aspx.
Remove extra tag and try.
you have a master page (i.e. MasterPage.master) and that will contain a form tag and you have added a form tag in your current page also (i.e. MainPage.aspx) remove current web page''s form tag i.e. remove
<form runat="server">
and
</form>
Thanks,
hemant
How come theformtag added here? You are using aMasterpage ! No need to have theformtag.Just get rid of it.
