I'm not sure about this, but :

C#

public void bindcombo()
{
    LogicLayer.Roles r = new LogicLayer.Roles();
    dbmodelDataContext ds = new dbmodelDataContext();@;

    cmbusertype.ItemsSource = ds.tblRoles.DefaultView;
    cmbusertype.DisplayMemberPath = "Role";
    cmbusertype.SelectedValuePath = "RoleId";
}

may work...

Have fun,
