Hi, I created a page (a unique aspx file) where I have all the controls in that page together and some of them are hidden but others are visible,according to the exact state of the page.The problem is that I do not want to load all the page again and again in every user's click,but only the parts of the page that are changed...

Such us, I have some imagebuttons and an image control in that page and if I click to an imagebutton to show its icon to the bigger image control,then all the page loads again,with the background image and all the stuff,visible or not.

Is there a way to avoid doing this?

Thanks in advance...

In order to skip parts of your page_load from running, simply put them inside an if statement like this:

If (!Page.IsPostback)
{

  anything you put in here will only get executed when the first page is loaded.

  make sure you pay attention to viewstate

}

Hi again,

 I did the following change but I think every stuff in page is loaded in every click....

1    If IsPostBack = False Then
2                Image1.ImageUrl = "images/background.gif"
3                Image2.ImageUrl = "images/riges4.gif"
4                Image3.ImageUrl = "images/logotipo1.gif"
5    End If

It is still the same behaviour....anyway thanks for the answer...

it is improssible  for u to don't reload all the page  except using  Ajax technology 

when u click a button in client browser  ,it will take  a request to the server ,and the server will give a response to u ,and at this time it will reload all the controls in you page .

 at last, i am sorry for my poor english.

1)Ok.I understood....but if I use Ajax technology,I think that all the site will become heavier,right?

2)How can I use this technology?

Thanks for your precious time...
