Dropdown if statement

Hi there,

In my asp application I am trying to navigate to a certain page based on a dropdown selection.

If I had :

Code:

---

<asp:DropDownList ID="DD_OptionSelect" data-role="none" runat="server">
        <asp:ListItem>Option 1</asp:ListItem>
          <asp:ListItem>Option 2</asp:ListItem>
 </asp:DropDownList>

---

and I also had:

option1.aspx and option2.apsx pages.

I would like to have an if statement for the dropdown selector.

something like :

IF the user has selected option one then goto option1.aspx

ELSE goto option2.aspx

Any help would be muchly appreciated. :)
