    <p>For increasing performance in my Asp.Net page I am trying to asynchronously load the asp.net page. I found this nice article on <code>encosia.com</code>:</p> <p><a href="http://encosia.com/boost-aspnet-performance-with-deferred-content-loading/" rel="nofollow">http://encosia.com/boost-aspnet-performance-with-deferred-content-loading/</a></p> <p>However problem is it is only possible to do that in case we need to display static content. For usercontrols having button etc, it is not really a viable solution.</p> <p>I need something like follows:</p> <pre><code>1) Asynschronously load all usercontrols 2) Each usercontrol has it's own ViewState may be by overriding `SavePageStateFromPersistedMedium/LoadPageStateFromPersistedMedium` so that when a control is posted back only relevant viewstate is posted rather than posting the whole control. 3) Must be able to handle atleast standard Asp.Net control postbacks Eg. Button's click etc. I won't be ever using Telerik's compoenents. </code></pre> <p>I did find one very nice article on codeproject:</p> <p><a href="http://www.codeproject.com/Articles/23768/Load-and-Display-Page-Contents-Asynchronously-with" rel="nofollow">http://www.codeproject.com/Articles/23768/Load-and-Display-Page-Contents-Asynchronously-with</a></p> <p>However due to the issues mentioned in comments I thought I rather not use it. However, I want something very similar in nature. Does anybody know of such a control? If not I don't mind developing it from scratch but can you guys provide general guidelines/concept behind how can I put these pieces together?</p>

    1. COi have created one example where i loaded gridview as a HTML using traditional ajax on click of link.. and on successful response i just added that to a div using innerHTML property.. similarly you can create different ajax request for each user control and return its HTML on one page append to the div as per the design.

    2. CO@Murtaza: This is the same concept which is demonstrated on encosia. However when you have a **CommandName** in any of the button controls in GridView, it won't work as ViewState is invalid.

    3. COyes this is because of `DataKeyNames` `Gridview` has its own `DataKeyNames` for each column but i think it is achievable. Can you try an example by loading 2 usercontrols on one page. After trying we can come across some better solution.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
