  Hi Dalia - welcome to developerFusion! Unfortunately you can't reference controls in that way. How are you creating the controls in the first place? You might want to consider adding them to a list as you create them, for instance: List myDynamicControls... // instance variable ... Control dynamicAddedControl = new Control(); myDynamicControls.Add(dynamicAddedControl) Then you could simply iterate your list of controls to fetch the values. Hope that helps

  Hi Dalia, can I only ask you why you are using these "hidden", and how (on customer-product or fruit-apple example). Maybe there is better mechanism instead "hidden fields"... i will try to find this if you show sense of hidden
