DropDownList In Datagrid!

[Adam Knight]

I have a DropDownList in the Footer of a datagrid ['dgTest'] like so:

<FooterTemplate>
<aspropDownList ID="cboParentId" Width="120px"
DataTextField="name" DataValueField="area_id"
Runat="server"></aspropDownList>
</FooterTemplate>

When i try to bind the DropDownList to a datasource i am getting null object
exception.
Ie: It doesn't appear to find the DropDownList.

Here is my code:

How do you set the DataSource property?
