Regarding UpdatePanel internal?
<p>suppose i have many heavy control is on the page. as for example i have three gridview populated on the page and one gridview &amp; button is inside the updatepanel. from this scenario we can understand that there will be huge viewstate on the page. so i want to know that if i click on button inside the updatepanel then all the viewstate will be submitted to server during partial postback or not. if huge viewstate submit to server and comes back to client then what is the advantage of partial postback because response time will be slower. so tell me how could i tune up the code that only required things will only submit to server. discuss the partial postback concept in detail as a result we can take right action to have good performance. thanks.</p>
