这不是XmlHttpRequest的工作方式！如果使用它显示内容，则需要从服务器返回一些响应给客户端-捕获它，然后使用它修改控件内容.

在ASP.NET AJAX的情况下(即使用脚本管理器和更新面板)，您尝试的操作将起作用.

解决方案:
不仅仅是在服务器上分配网格源，而是在客户端获取新的网格xml并通过Javascript将其分配给网格以查看更改.
发送XMLHttpRequest之后的步骤如下:
1.生成绑定到网格的新数据的新html
2.将其发送回客户端
3.使用收到的html填充网格容器.

现在，我知道这不是您第一次问这个问题.我没有发布任何XMLHttpRequest链接，因为已经与您共享了.
我现在告诉你了这个概念.只需尝试将其放入XMLHttpRequest实现中即可.

This is not how XmlHttpRequest work! If you use it display something, then you need to return some response back to client from server - catch it and then modify the control content with it.

What you are trying would work in case of ASP.NET AJAX (i.e. with Script manager & Update Panel).

Resolution:
Instead of just assigning the grid source on server, get back the new grid xml on client side and assign that to the grid via Javascript to see the change.
Thus steps after XMLHttpRequest sent:
1. Generate the new html of the new data bound to grid
2. Send that back to client side
3. Use the recieved html to fill in the grid container.

Now, I know this is not the first time you are asking this question. I am not posting any XMLHttpRequest links because that has already been shared with you.
I told you the concept now. Just try to put it in the XMLHttpRequest implementation.
