How to make a DropDownlist PostBack smoother

I have a dynamic drop downlist on my Form, but when ever the user selects his value, it jumps around back to the top of the page, and then the user has to scroll back down to the page to where they left off. It is rather annoying. Is there a way to have the page not move. I hear you can use AJAX but I'm not very familiar with how that works.

		Select Basin:
		<br />
		<asp:dropdownlist id="ddlBasin" runat="server" AutoPostBack="True" 
    DataSourceID="SqlDataSource1" DataTextField="Basin" 
<asp:SqlDataSource id="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:Prop_ChangeConnectionString %>" 
    SelectCommand="SELECT [Basin] FROM [PC_CoalBasin]"></asp:SqlDataSource>
<br />
Select Ownership Codes:
<br />
<asp:dropdownlist id="ddlOwnership" runat="server" DataSourceID="SqlDataSource2" 
    DataTextField="Ownership" DataValueField="Ownership"></asp:dropdownlist>
<asp:SqlDataSource id="SqlDataSource2" runat="server" 
    ConnectionString="<%$ ConnectionStrings:Prop_ChangeConnectionString %>"    
    SelectCommand="SELECT [Ownership] FROM [PC_BasinOwnership] WHERE ([Basin] = @Basin)">
        <asp:ControlParameter ControlID="ddlBasin" Name="Basin" 
            PropertyName="SelectedValue" Type="String" />

Thank you, that worked great! I don't have time to learn AJAX right now, but I'll definitely look into that for future projects.
