Hello, Language is VB I have created a question form which has a text box where a user can type their question.

During testing, I can add text to the box and use the Sql Insert command to add a record in my sql database table.

To implement that you need to add 4 "things" in your ASP. You need a textbox to store the value you want to pass over to the Update Panel, but you don't want to show it in the page, so it must be hidden via CSS.

You see that I registered an Async Post Back Trigger on the Click event of the button.

That event probably reads in the value of your form elements to prepare a SQL INSERT/UPDATE, right? NET, every event handler still runs Page_Load first.

So if you are initializing the values of your textbox in Page_Load, what happens is the user puts their values in the textboxes and they click the button. Page_Load runs, and sets the value of the textbox to the default value, then the event handler function for the button runs.

In this article, I ll explore some of the issues and common actions related to postback, especially on the client side.

NET Ajax, but even looking around a lot I didn't find a clean and polished solution for what should be a common task. NET Ajax extender for such a simple task, but after a few hours of Google-ing, I found a few nice articles on Ben Rush's blog, which is a very valuable source of knowledge on the internals of ASP. The only thing you need to do to refresh from javascript is to register a Button (hidden via CSS) Click event as async trigger for an Update Panal and then call the following method from your javascript method: Yes, that easy. But in my page I also had to pass a value to the Update Panel, so the button was not enough.
