Introduction

I always wanted to be able to fill a panel with information gathered from all around the page directly after my end user selected his options and present them into a summary. Dynamic populate extender is a nice controller of a panel that is expected to be filled dynamically at the choices of the user. This article will show an example on how I used the control to provide the user with feedback about the extra preferences that a customer would select on a page. The whole project is attached for your own review. Let us examine my simple Pizza selection screen.

I am currently facing the need to dynamically generate a long detailed report with data retrieved from a database in an ASPNET 3.5 project in which I already use the AJAX Control Toolkit intensively. The data is provided by an ASPNET web service. The generated report is static and meant to be printed. My problem is that the data retrieval process takes about 10-15 seconds because of the database query execution time. I have the need to make the report page appear faster. I was wondering if it's possible for the report page to appear immediately with blank data and for the dynamic data to be written in the page as they arrive. In the page the data is contained in html tables with Label server controls in them and everything is inside an UpdatePanel. The report is made of different sections for each of which I have build a separate web method to provide the data. I have tried the asynchronous calls to the web service that provides the data, handling the task completion event for each of the methods, but the page doesn't load until all the data has arrived.
What solutions would you suggest?

This article doesn't give proper code. For example, TargetcontrolId="Pannel1", it doesn't have this control at all, if we copy this code as it is available to our page, then how our page will create pannel control?. Don't publish irrelevant article from now onwards.... I Hope u got my point..
