The background is I have a custom control that is a asp:Menu that is linked to an xmldatasource. The xmldatasource is created dynamically depending on the user privies. Here is the load event for the custom control:
  protected void Page_Load(object sender, EventArgs e)
    {
        string userId = (string)Session["userId"];
        if (userId != null)
        {
            DataSet ds = dal.RetrieveApplications(userId);
            ds.DataSetName = "Menus";
            ds.Tables[0].TableName = "Menu";
            DataRelation relation = new DataRelation
            ("ParentChild",
                ds.Tables["Menu"].Columns["Folder_Id"],
            ds.Tables["Menu"].Columns["Parent_Folder_ID"], true);
            relation.Nested = true;
            ds.Relations.Add(relation);
            xmlDataSource1.Data = ds.GetXml();
        }
}
This works perfectly for the first user that uses it. But it seems that every subsequent user is actually getting the first user's menu. I have walked it through and verified that my dataset is getting created fine and when I examine the XMLDatasource.data at the end of the load the xml is correct.
I am really stuck.
