How can I use AutoPostBack inside UpdatePanel

I have two DropDownLists inside an UpdatePanel.

The values shown inside the second are dependent of the selectedValue on the first, so, I need AutoPostBack=true.

But, whenever the selected value in the first DropDownList is changed causes the UpdatePanel reload.

How can this be solved?

PS.: The UpdatePanel's UpdateMode property is set to Conditional.

Thanks.

A: 

Resolved by adding the Page_Init to execute some rules only at the first charge.
