Filter listbox contents client-side

I have a .Net web application created with c# using Visual Studio 2010.

On a web page a have a DropDownList containing containing a list of publishers. Below that I have ListBox displaying books for the selected publisher. I would like the list to update when the users selects a publisher in the DropDownList. I can do this server-side but how can I do it client-side for quicker performance?

A link to the page would be helpful; or at the very least the HTML that the browser is seeing.

It is something I am developing. Just an asp:DropDownList followed by an asp:ListBox. If it helps it will look like:

          <asp:DropDownList ID="DropDownList1" runat="server">
              <asp:ListItem Value="1">Publisher 1</asp:ListItem>
              <asp:ListItem Value="2">Publisher 2</asp:ListItem>
          </asp:DropDownList>
      </p>
      <p>
          <asp:ListBox ID="ListBox1" runat="server">
              <asp:ListItem Value="1,1">Book1</asp:ListItem>
              <asp:ListItem Value="1,2">Book 2</asp:ListItem>
          </asp:ListBox>
