    error: Unable to cast object of type 'Telerik.Web.UI.RadMultiPage' to type 'System.Web.UI.UserControl'.

    When going through a user control for a EditFormUserControl and I wanted to list all the user controls on that page but doing a foreach loop I need a fairly consistent type to iterate through.  So how can I iterate through 'userControl' when it could be a lteral for a label or  a 'RadMultiPage' or a 'UserControl'.  I have tried ...string objectTypeName="RadMultiPage";

     

    Type

     

    T = Type

     

    .GetType(objectTypeName);

     

    ((

    typeof(T)))userControl).Controls

     

     

    But I just wanter to be able to have a reursive call listing out all the children be them Usercontrol or Telerik User controls. 
    Any Ideas ?

    UserControl userControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID);

    foreach

     

    (object uc in ((UserControl)userControl).Controls){}
