Re: New to ASP.NET - A very basic question regarding the ViewState and Server Round Trips

Tech-Archive recommends: Fix windows errors by optimizing your registry

Steve,

Thanks for the info.

Here is what I observed in my ASP.NET application.

Observation 1:
Every time I do refresh (ctrl-F5) even if I add a text in my text box it is
cleared and whenever I do refresh I am geting fresh page with no text. So
this is exactly what I am expecting.


Observation 2:
When I click once on the ASP:Button which is on my page, then the page is
not loading but only the Postback event is happening. So during this
Postback event whatever Text info I used for the First Submit always stays
in my text box. Even if I change the value latter and then do a refresh
whatever Text Info I used for the First Submit stays in the text box.

So my question is

What is happening during the "ASP:Button" click event?

I thought it makes a round trip to server and behave same as the initial
page load event but it is not like that.

Can you please clarify?

Thanks
Anand Ganesh
