Object data source, setting parameter source to Page.Partner.Guid

I'm trying to databind using an object data source to a dropdownlist in
asp.net 2.0, The method I'm databinding to takes a parameter. My page is a
page I've implemented by inheriting from the normal page object, and it has
a property called Partner that in turn has a property called Guid. I would
like to pass the Page.Partner.Guid as a parameter to the method that I'm
databinding to. How can I do this, I can choose parameter source to None,
Cookie, Control, Form, Profile, Querystring, Session.
But I cant find my Page.Partner.Guid in any of those options, the page
control is not listed in Control.
What is Profile? Could I add my Partner object to the profile?

How do I get this to work?

Kind Regards,
Allan Ebdrup

Hi Allan,

You can just select "None" for the parameter type and pass the parameter
value in ObjectDataSource's Selecting event:

    protected void ObjectDataSource1_Selecting(object sender,
ObjectDataSourceSelectingEventArgs e)
    {
        e.InputParameters["guid"] = this.Partner.Guid;
    }

You can add a custom type as a Profile property by:

    <system.web>
    <profile>
      <properties>
        <add name="Partner" type="mynamespace.Partner"/>
      </properties>

However, since your ObjectDataSource's using the Partner.Guid as parameter,
you cannot directly use Profile.Partner as its parameter.

Please reply to let me know whether or not you need further information.

I found a workaround:
I simply save the property in a hidden field, in Page_Load, that is not
visible and let teh object data source get its parameter from there.
