好的，所以我有一个包含radgrid和表单的页面。通过表单创建新记录并重新绑定网格时，它可以正常工作。最初绑定网格时，它工作正常。只有在单击网格中的删除按钮，处理自定义命令和重新绑定时，才会出现此错误。
在表单上，有radtextbox，radcombobox，radspell和其他控件。我注意到堆栈跟踪中的RadSpell.CreateChildCOntrols ...这是否意味着错误在哪里？我还看到ASP.views_shared_header_ascx.__Render__control1的引用，它是一个用户控件，并且里面有一些控件/ AJAX。
另外，我对PreRender有约束力 - 这对于做同样事情的应用程序的其余部分来说不是问题;在这个页面中，它只发生在这一个地方，而不是在其他两个地方，这些地方都是预渲染...
为什么会发生这种错误？
感谢。
