Handle Multiple Postbacks with AspQ
Several developers have released various server-side and client-side implementations to deal with multiple postbacks. But as a developer, you need to have deep domain knowledge to understand the implemented solutions.
Add the following server-side code in your OnInit method of the System.Web.UI.Page
form runat="server" onsubmit="return AspQ.submit(this)">
The developer has provided another implementation for working with AspQ on the official project site and on his blog.
I released AspQ because there wasn't a drop-in solution addressing the problem of multiple postbacks for ASP.NET. You probably won't see performance improvements using AspQ, except perhaps in your user's workflow because they no longer have to wait for one async postback to complete before continuing to work, said Sandro Magi, Developer, AspQ.
