SqlDataSource param in ItemTemplate can't find GridView bound cont

[Dabbler]

I'm trying to load a DropDownList in a Gridview from a secondary
SqlDataSource but I get an exception complaining that the ControlParamete r's
ControlId isn't found.
"Could not find control 'JoinDate' in ControlParamete r 'JoinDate'."

<asp:BoundFie ld DataField="Join Date" HeaderText="Joi ned"
SortExpression= "JoinDate" />
<asp:TemplateFi eld HeaderText="Dat es">
<ItemTemplate >
<asp:DropDownLi st ID="RideDatesDr opDownList" runat="server"
OnDataBound="Sh owHideDatesDDL"
DataSourceId="R ideDatesSqlData Source" DataTextField=" RideDate"
DataValueField= "RideDate"
DataTextFormatS tring="{0:MMM yyyy}" CssClass="waDro pDownList">
</asp:DropDownLis t>
<asp:SqlDataSou rce ID="RideDatesSq lDataSource" runat="server"
ConnectionStrin g="<%$ ConnectionStrin gs:myDB %>"
ProviderName="S ystem.Data.SqlC lient"
SelectCommand=" GetCurrentRides Taken_desc"
SelectCommandTy pe="StoredProce dure">
<SelectParamete rs>
<asp:ControlPar ameter ControlID="Regi strantIdLabel"
Name="Registran tId" Type="Int32" />
<asp:ControlPar ameter ControlID="Join Date" Name="JoinDate"
Type="DateTime" />
</SelectParameter s>
</asp:SqlDataSour ce>
</ItemTemplate>
</asp:TemplateFie ld>

Any illumination would be appreciated, I'm stuck ;)

The BoundField object renders different objects based on the databound
control in which it is used. It is not a control that has an ID. You might
replace the BoundField with a TemplateField inside which you bind another
server control, e.g. a Label, give it an ID and refer to it using the
Controlparamete r.

Super duper! I can do that.

Thanks much.
