SqlDataSource error in Accordion

[staeri@gmail.com]

I have a dropdownlist attached to a SqlDataSource inside an Accordion.
I receive the following error message when the SqlDataSource is inside
the Accordion:

"The DataSourceID of 'ddGroup' must be the ID of a control of type
IDataSource. A control with ID 'SqlDataSourceG roup' could not be
found."

I've been suggested to move the SqlDataSource out of the Accordion to
get rid of the error message above, but when I do so the SqlDataSource
can't find the ControlParamete r (another dropdownlist which is also
inside the Accordion). I then receive the following error message:

"Could not find control 'ddProjectType' in ControlParamete r
'ProjectTypeID' "

Here is my SqlDataSource:

<asp:SqlDataSou rce ID="SqlDataSour ceGroup" runat="server"
ConnectionStrin g="<%$ ConnectionStrin gs:MyConnection String %>"

SelectCommand=" spPROJECTMenuLe velGet"
SelectCommandTy pe="StoredProce dure">

<SelectParamete rs>

<asp:Paramete r Name="MenuLevel " DefaultValue="G ROUP" />

<asp:ControlPar ameter ControlID="ddPr ojectType" DefaultValue="% "
Name="ProjectTy peID"

PropertyName="S electedValue" />

<asp:SessionPar ameter SessionField="v arUserID" Name="UserID" />
</
SelectParameter s>
</
asp:SqlDataSour ce>

Does anyone have a solution to this problem?
