Find Value of Combobox in RadPanel

[Aaron]

I am trying to do a redirect in codebehind based on the value a user has selected in a combobox.  Can someone please tell me how to access the value? Using VB.NET please!

Thanks!    

**UPDATE: How do I access the button as well?  Can someone give me a codebehind example please in VB.NET  

<telerik:RadPanelBar ID="RadPanelBar2" Runat="server" Width="100%" ExpandMode="SingleExpandedItem">
                    <Items>
                        <telerik:RadPanelItem runat="server" Text="PURCHASE ACCOUNT CREDITS">
                            <Items>
                                <telerik:RadPanelItem Value="AccountCredits" runat="server">
                                    <ItemTemplate>
                                        <table width="100%" border="0" cellspacing="2" cellpadding="2">
                                            <tr align="center">
                                                <td>How many credits would you like to purchase?</td>
                                            </tr>
                                            <tr align="center">

Hi Aaron,

You can access the controls as follows.

VB:

Dim rcb As RadComboBox = DirectCast(RadPanelBar2.FindItemByValue("AccountCredits").FindControl("cbxCredits"), RadComboBox)
Dim value As String = rcb.SelectedValue
Dim btn As RadButton = DirectCast(RadPanelBar2.FindItemByValue("AccountCredits").FindControl("btnCheckout"), RadButton)

Thanks,
Shinu.

How would you do that in javascript?
