user control not updating on postback-31

If anyone here knows a lot about Web Forms, and especially Update Panel behaviour, then I would love to hear from you.

This sample code was quickly put together in a fresh Web Forms project and can be copied and pasted to see the strange problem I am having. I have a basic Web Forms page using the default master page generated by a new Web Forms project.

I'm just learning about updating content without postback, new for me! I have 3 dropdownlists which need to look up some nodes and then update content based on their selection without a postback, what would be the best way to do this?

I've seen some references about using umbraco REST/JSON base?

If you approach from a URL-driven page load perspective, where each URL (with query string data) represents a page state the amount of time you'll need to take to track down an issue will be (hopefully) cut down to the amount of time it takes you to copy a URL and paste it into your browser navigation bar.

I personally think this is the most compelling argument for trying to avoid a stateful approach web events whenever possible.

This page contains an Update Panel: Inside this Update Panel is a custom User Control.

The User Control has a Grid View and some other arbitrary controls containing links.

Means if you fill all your detail in web registration form and click on submit then after postback if the page again comes back with any validation error issue then all of your filled data lost from all textboxes and other controls on form.

This only happens if these controls will not maintaining there state. Cause they dont have any viewstate to maintain their data .
