(thanks read whole post)

-----------------updated solution--------------------------------------------

i decided change , store list db @ page_load. list stored loop through list , use findcontrol() access textboxes. this..

//a couple containers protected class itemval {     public int value { get; set; }     public string name { get; set; } } protected list<itemval> items = new list<itemval>();    //get list database protected void getitems() {     foreach (var x in myclass.getitems())     {         itemval = new itemval();         i.name = x;         items.add(i);     } }  //submit protected void submit_click(object sender, eventargs e) {     foreach (var x in items)     {         radnumerictextbox rntb = findcontrol(x.name) radnumerictextbox;         x.value = (int)rntb.value;     } } 

you need cast x radnumerictextbox , pull out property values want, this:

radnumerictextbox theradnumerictextbox = x radnumerictextbox; string val = theradnumerictextbox.text; 

then other controls want, need put if conditions types, this:

if (x label) {     label thelabel = x label;     string vallabel = thelabel.text; } 

here full code method:

protected void submit_click(object sender, eventargs e) {     foreach (control x in findcontrol("panel1").findcontrol("table1").controls)     {         label thelabel;         radnumerictextbox theradnumerictextbox;          if (x radnumerictextbox)         {             radnumerictextbox theradnumerictextbox = x radnumerictextbox;             string val = theradnumerictextbox.text;         }          if (x label)         {             label thelabel = x label;             string vallabel = thelabel.text;         }          // either store in list or save database on each loop; recommended store list , send changes @ once database save, choice     } }
