Error When Databinding to Control

I am having trouble getting my datasource linked to my repeater through this code

protected void Page_Load(object sender, EventArgs e)
{
    //HiddenField used as a placholder
    HiddenField username = list.FindControl("username") as HiddenField;
    //list is a DataList containing all of the user names
    list.DataSource = Membership.GetAllUsers();
    list.DataBind();
    //Creates a string for each user name that is bound to the datalist
    String user = username.Value;
    //profilelist is a repeater containing all of the profile information
    //Gets the profile of every member that is bound to the DataList
    //Repeater is used to display tables of profile information for every user on
    // the site in a single webform
    profilelist.DataSource = Profile.GetProfile(user);
    profilelist.DataBind();

}

I am getting the error message

An invalid data source is being used for profilelist. A valid data source must implement either IListSource or IEnumerable.

I forgot to post this up but for anyone that needs to do something similar here is the code behind that works

protected void Page_Load(object sender, EventArgs e)
{
    List<MembershipUserCollection> usernamelist = new List<MembershipUserCollection>();
    usernamelist.Add(Membership.GetAllUsers());
    List<ProfileCommon> myProfileList = new List<ProfileCommon>();
        foreach (MembershipUser user in usernamelist[0])
        {
            string username = user.ToString();
            myProfileList.Add(Profile.GetProfile(username));
            Label emailLabel = profilelist.FindControl("EmailLabel") as Label;
        }
}

At the moment this is displaying about 15 user names and providing an ability to link to each of theses users respective profiles.

Well the reason why it will not work is because Profile.GetProfile returns ProfileCommon. As the error states the type you set profilelist.Datasource equal to, must be IListSource or IEnumerable.

I would suggest not using a repeater since you don't have actual repeating data to display.

EDIT

I think this is what you want to do.

        IEnumerable<ProfileCommon> myProfileList = new IEnumerable<ProfileCommon>();

        foreach(var user in userlist)
        {
             myProfileList.Add(Profile.GetProfile(user));
        }

        profilelist.datasource = myProfileList;

Your going about this wrong. As Etch said, a repeater is for lists of things. GetProfile doesn't return a list.

You're better off just putting your controls in a panel and assigning them in the "list" controls ondatabinding event.

In other words, you don't need a repeater here.
