hi,
when i press the button ,its make my page read th e page load again.
its a problem for me because my page load have must reading a new topic all the time.(its a random page).
so instead reading my button event its refresh my page.

sorry about my awful english

Use Page.IsPostBack to see if you are in a postback in the page load event.

Think before you post: What have you tried?

yes postback=true,
what should i do now?

:) No, that's not what he means.

In the button postback=true will trigger a postback, yes.

Now you want the code behind to do different things if the page is postback or not. Typically you break items up into three groups like this...

protected void Page_Load(...blahblah...)
{

... This is code you always want executed whether the page is postback or not...

if (Page.IsPostBack)
{
...Code that should only execute if the page IS postback...
}

if (!Page.IsPostBack)
{
...Code that should only execute if the page id NOT postback, the exclamation point means "not"...
}
}
