Access web user control in code behind

[Robert]

I have a web user control(NavigationControl.ascx) where I build a PanelBar and it contains another web user control.

<telerik:RadPanelBar runat="server" ID="SearchOptionsPanel" Width="172px" Skin="CMASkin" EnableEmbeddedSkins="false"
    OnClientItemClicked="PanelBarItemClicked">
    <Items>
        <telerik:RadPanelItem Text="Search Options" Expanded="true" Value="MeasureOptions">
            <Items>
                <telerik:RadPanelItem Text="">
                    <ItemTemplate>
                        <uc1:DischargeListCriteriaControl ID="DischargeListCriteriaCtrl" runat="server" />
                    </ItemTemplate>
                </telerik:RadPanelItem>
            </Items>
        </telerik:RadPanelItem>
    </Items>
</telerik:RadPanelBar>

How do I access the "DischargeListCriteriaControl" from the codebehind of the NavigationControl.ascx.cs.  The below doesn't work.

public DischargeListCriteriaControl DischargeListCriteriaControl
{
    get
    {
        return this.DischargeListCriteriaCtrl;
    }
}

figured it out.

public DischargeListCriteriaControl DischargeListCriteriaControl
{
    get
    {
        return ((DischargeListCriteriaControl)this.SearchOptionsPanel.Items[0].Items[0].FindControl("DischargeListCriteriaCtrl"));
    }
}
