Ajax with multiple panels

 Hello:

For example: I have a Students.aspx page using Ajax with 3 different panels like below and each panel contains different code. I have a main page that have links to Students.aspx page and I have set the property Visible=True to panel 1. My question is How do I make so that when clicked on Student 1 from the Main.aspx, it will call panel1 and when clicked on Student 2 from the Main.aspx, it will call panel2...etc...Thank you.

Students.aspx

<ajax:Update Panel ID="studentUpdatePanel" runat="server" UpdateMode="Conditional">  

<ContentTemplate>

      <asp:Panel ID="panel1" runat="server" Visible="true">Code for student 1</asp:panel>    

     <asp:Panel ID="panel2" runat="server" Visible="false">Code for student 2</asp:panel>    

     <asp:Panel ID="panel3" runat="server" Visible="false">Code for student 3</asp:panel>

 </ContentTemplate>

</ajax:UpdatePanel>

Main.aspx

<a href="Students.aspx">Student 1</a>

<a href="Students.aspx">Student 2</a>
