What else part are you talking about - you didn't show that code? Page is supposed to postback on button click, that's how ASP webforms work.
Explain what you are trying to achieve.

Well, what is the question.
Page will definitely post back on button click (or any such event or server side control). You need to handle your code in Page_Load using isPostBack

C#

protected void Page_Load(object sender, EventArgs e)
{

if (!IsPostBack)
{
//First time page load
}
else
{
// subsequent page load
}

Hope that helps
