          <asp:ImageButton ID="img_prependdate" ImageUrl="~/content/img/calender.gif" runat="server" OnClick="img_prependdate_Click"  />
          <asp:Calendar ID ="cal_prenddate" runat="server" Visible="false" ShowGridLines ="true" style="Z-INDEX: 1; LEFT: 362px; POSITION: absolute; TOP: 365px"  autopostback="true" OnSelectionChanged="cal_prenddate_SelectionChanged"></asp:Calendar>

That's because the image button is causing the whole page to be refreshed. The only way to guarantee that doesn't happen is to do whatever you're doing using javascript\ajax rather than using an image button and postbacks. You could also try putting the relevant controls inside an UpdatePanel to see if that helps.
