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.
