Can a ControlParameter be used to supply a parameter for a stored procedure?

The code below is an attempt at using the value from a dropdownlist to feed into stored procedure outlined in the Select command. I have seen examples where the control parameter is used with a select command but nothing where the parameter has to be fed into a stored procedure.

<

asp:SqlDataSourceID="SqlDataSource1"runat="server"ConnectionString=".."
SelectCommand="procCAGetCustomerKPIs"SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:ControlParameterName="iCustomerGroupId"ControlID="CustomerFilterList"PropertyName="SelectedValue"/>
</SelectParameters>
</asp:SqlDataSource>

Yes. Normally, I would use the designer, and hit "refresh parameters", it will then generate a list of all the parameters the stored procedure is expecting. From that point, change the parameters from type "None" to "Control", etc.|||Forgot to add autoPostBack=true to the dropdownlist control!!
