Greg,
A great way to start using AJAX in ASP.Net 2.0 in your web pages is by
using the CallbackPanel control which is part of Essential Tools for
ASP.Net from Syncfusion.
The scenario you mention above could be easily implemented as follows:
1) In JS you would invoke a callback to the server on say a button
click for example as follows:
_sfCallbackPanel1.callback("some custom args");
2) This will fire the CallbackPanel1.Callback event on your page on the
server, where you can clear and populate the CallbackPanel (Panel
derived class) with a whole new set of controls.
3) The callback will return and refresh your page with the new content.
Take a look at all our AJAX samples at:
http://www2.syncfusion.com/2.0/samples.aspx
.... and browse to Tools.Web/CallbackControls in the tree on the left.
There is also a ProgressBar control which can be used to display the
status of long operations in a AJAX/Callback scenario like above at
Tools.Web/ProgressBar.
