Custom Advanced Insert Template With autopostback dropdowns

[Bex]

Hi

I am trying to create a custom insert template.
When a user adds an appointment they assign it to other users and I am trying to add the ability to narrow down the users via dropdowns within the template.
I have two dropdowns, Organisation and Section, organisation posts back to populate the sections, then when a section is selected it populates a users checkboxlist based on the results.


In the AdvancedControlsPanel I have the following:

<asp:Panel runat="server" ID="AdvancedControlsPanel" CssClass="rsAdvMoreControls">
                        <label>
                            Type:
                        </label>
                        <!--
-->
                 <asp:Panel runat="server" ID="pnlUsers">
                            <label>
                                Users:</label><br />
                            Search for users
                            <asp:DropDownList ID="ddlOrganisation" runat="server" OnSelectedIndexChanged="ddlOrganisation_SelectedIndexChanged"
                                AutoPostBack="true">
                            </asp:DropDownList>
                            Sections
                            <asp:DropDownList ID="ddlSections" runat="server" OnSelectedIndexChanged="ddlSections_SelectedIndexChanged"
                                AutoPostBack="true">
                            </asp:DropDownList>
                            <asp:CheckBoxList runat="server" ID="chkUsers">
                            </asp:CheckBoxList>
                        </asp:Panel>
                        <asp:Panel runat="server" ID="ResourceControls">
                        </asp:Panel>
                    </asp:Panel>

When the postback happend all the rest of the controls in the insert window blanked so I tried putting these in an ajaxpanel and registering it with the scriptmanager as it was saying it needed registering when the dropdown did the autopostback.
I did this on the advanced form page load like so 

sm1.RegisterScriptControl(ajaxpnl);

but I got an error saying

script controls may not be registered before PreRender

I also tried using a ajaxmanager proxy against the dropdowns but this just seemed to replicate the controls down the page.

My main page has a RadAJaxManager on it and the radscheduler is ajaxified.

Is there any examples anywhere of how I can get this to work?
I know its a problem with my ajax but I can't get my head round it!

Having dug around a bit more I can see my problem isn't as simple as it appeared.
I have ran the examples and added my code standalone and it all works. It is something to do with the way I have everything set up.
I plan on compiling it all in a small project and creating a support ticket.
