[Solved] AJAXManager, RadComboBox, and RadTreeview

[John Snyder]

I have a combobox that uses a treeview for it's item selection.  Upon selection of an item in the treeview I want to do some server side processing. At the same time, I want all this ajaxified and thus I am using RadAjaxManager.

What AjaxControlID do I put in for the AjaxManager to allow for the updates to work properly?  If I do not put anything in the AjaxManager it will work without a postback so I know that code is correct.  I tried adding in the RadComboBox1 as the AjaxControlID and that gives me a JS error of "Unknown runtime error".

Here is the code for my AjaxManager:

    <telerik:RadAjaxManager id="RadAjaxManager1" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="RadComboBox1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="trActions" />
                    <telerik:AjaxUpdatedControl ControlID="trDocuments" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="lbCloseDocument">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="trActions" />
                    <telerik:AjaxUpdatedControl ControlID="trDocuments" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>

Here is the code for my combobox:

<telerik:RadComboBox ID="RadComboBox1" runat="server" Width="215px" Skin="Outlook">
    <ItemTemplate>
        <telerik:RadTreeView ID="RadTreeView1" runat="server" Height="200" OnNodeClick="RadTreeView1_NodeClick">
            <Nodes>
                <telerik:RadTreeNode runat="Server" Text="First Doc" Value="/files/First.pdf" />
                <telerik:RadTreeNode runat="Server" Text="Second Doc" Value="/files/Second.pdf" />
                <telerik:RadTreeNode runat="Server" Text="Third Doc" Value="/files/Third.pdf" />
                <telerik:RadTreeNode runat="Server" Text="Category 1">
                    <Nodes>
                        <telerik:RadTreeNode runat="Server" Text="Doc 1" />
                        <telerik:RadTreeNode runat="Server" Text="Doc 2" />
                        <telerik:RadTreeNode runat="Server" Text="Doc 3" />
                    </Nodes>
                </telerik:RadTreeNode>
                <telerik:RadTreeNode runat="Server" Text="Category 2">
                    <Nodes>
                        <telerik:RadTreeNode runat="Server" Text="Doc 4" />
                        <telerik:RadTreeNode runat="Server" Text="Doc 5" />
                        <telerik:RadTreeNode runat="Server" Text="Doc 6" />
                    </Nodes>
                </telerik:RadTreeNode>
            </Nodes>
        </telerik:RadTreeView>
    </ItemTemplate>
    <Items>
        <telerik:RadComboBoxItem Text="" />
    </Items>
</telerik:RadComboBox>
