Edit Template with conditional controls

I have a grid that uses an edit form template. The template includes a dropdown that needs to control the visibility of other controls on the form based on the selection. I intend to do this with a selected index changed event. How do I get a reference to the edit form controls on the page within a SelectedIndexChanged event of a dropdown?

<EditFormSettings EditFormType="Template">

<EditColumn ButtonType="ImageButton" />

<FormTemplate>

<table cellpadding="2" cellspacing="1" border="0" style="font-size: small; border-collapse: collapse;

background: white;">

<tr valign="top">

<td colspan="2" align="left">

<b>Document Details</b>

</td>

</tr>

<tr valign="top">

<td class="ContentWhite">

<span class="Error">*</span>Document Type:

</td>

<td class="ContentWhite" align="left">

<telerik:RadComboBox ID="rcbDocumentType" runat="server" EnableItemCaching="true" MaxHeight="300px"

OnSelectedIndexChanged="rcbDocumentType_SelectedIndexChanged">

<Items>

<telerik:RadComboBoxItem Value="-Select-" Text="-Select-" />

<telerik:RadComboBoxItem Value="1" Text="W9" />

<telerik:RadComboBoxItem Value="2" Text="E&O" />

<telerik:RadComboBoxItem Value="3" Text="License" />

<telerik:RadComboBoxItem Value="4" Text="Vendor Acknowledgement" />

<telerik:RadComboBoxItem Value="5" Text="Master Listing Agreement" />

<telerik:RadComboBoxItem Value="6" Text="State Registration" />

</Items>

</telerik:RadComboBox>

<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" Display="None"

ValidationGroup="vgDocument" ControlToValidate="rcbDocumentType" InitialValue="-Select-"

ErrorMessage=" Document Type is required " />

</td>

</tr>

<tr valign="top">

<td class="ContentWhite">

<asp:Label ID="lblManagingBrokerFirstName" runat="server" Text="First Name:" Visible="false" />

</td>

<td class="ContentWhite" align="left">

<telerik:RadTextBox ID="rtbManagingBrokerFirstName" runat="server" MaxLength="128" />

</td>

</tr>

<tr valign="top">

<td class="ContentWhite">

<asp:Label ID="lblManagingBrokerLastName" runat="server" Text="Last Name:" />

</td>

<td class="ContentWhite" align="left">

<telerik:RadTextBox ID="rtbManagingBrokerLastName" runat="server" MaxLength="128" />

</td>

</tr>

How do I toggle the visibility of the radtextbox (rtbManagingBrokerLastName) in the selected index changed event of the combobox (rcbDocumentType)?
