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>

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!
