c# - add text box dynamically and capture data on button click -

i adding text boxes dynamically , trying capture data entered in text box on button click. happening , though entered data in text box, when clicked button, page getting loaded , control getting created again. result , loosing data in text box. can tell me how can capture data entered dynamically created text boxes. sample code follows:

   protected void page_load(object sender, eventargs e)     {         table tbltextboxes = new table();         for(int i=0;i<10;i++)         {             tablerow tr=new tablerow();             tablecell tc=new tablecell();             textbox tb=new textbox();             tb.id=i.tostring();             tc.controls.add(tb);             tr.cells.add(tc);              tablecell tc1=new tablecell();             linkbutton lnk=new linkbutton();             lnk.id=i.tostring()+tb.text+"lnk";             lnk.text = "show";             lnk.click+=new eventhandler(lnk_click);             tc1.controls.add(lnk);              tr.cells.add(tc1);              tbltextboxes.rows.add(tr);         }         placetest.controls.add(tbltextboxes);     }    void  lnk_click(object sender, eventargs e) { linkbutton lnk=sender linkbutton; label lbl=new label(); lbl.text="the text is"+lnk.id; placetest.controls.add(lbl); } 

linkbutton id changed every time enter text textbox , post back.

one thing want make sure when creating control dynamically - want recreate them same id when post back.

updated solution (to retrieve text textbox)

protected void page_load(object sender, eventargs e) {     var tbltextboxes = new table();     (int = 0; < 10; i++)     {         var tr = new tablerow();         var tc = new tablecell();         var tb = new textbox {id = i.tostring()};         tc.controls.add(tb);         tr.cells.add(tc);          var tc1 = new tablecell();         // fix - lnk.id=i.tostring()+tb.text+"lnk";         var lnk = new linkbutton {id = + "lnk", text = "show"};         lnk.click += lnk_click;         tc1.controls.add(lnk);          tr.cells.add(tc1);          tbltextboxes.rows.add(tr);     }     placetest.controls.add(tbltextboxes); }  void lnk_click(object sender, eventargs e) {     var lnk = sender linkbutton;     var lbl = new label();     lbl.text = "linkbutton id: " + lnk.id;      // number value string     string id = regex.replace(lnk.id, @"[^\d]", "");      // retrieves textbox control id         var control = findcontrolrecursive(page, id);      if (control != null)     {         var textbox = control textbox;         lbl.text += "; textbox text: " + textbox.text;     }      placetest.controls.add(lbl); }  public control findcontrolrecursive(control root, string id) {     if (root.id == id)         return root;      return root.controls.cast<control>()         .select(c => findcontrolrecursive(c, id))         .firstordefault(c => c != null); }
