c# - How can I get the value of a dynamically created checkbox when the submit button is clicked? -


i have asp.net page has 2 controls on it, placeholder , submit button. during page_load create checklist of tasks dynamically. each row consists of description, link tutorial, , checkbox. of information in row kept in database. if database says task has been checked, code sets checked property true. problem i'm having when submit button clicked cannot find value of checked property of checkboxes on page(about 23 total).

here code create checkboxes...

checkbox = new checkbox(); phchecklist.controls.add(checkbox);  if (item.attributes.contains("ree_completed")) checkbox.checked = (bool)item.attributes["ree_completed"];  checkbox.enableviewstate = true; checkbox.clientidmode = system.web.ui.clientidmode.static;  checkboxid = "checkbox" + (string)item.attributes["ree_sectionnumber"].tostring() + (string)item.attributes["ree_sequencenumber"].tostring(); checkbox.id = checkboxid;

here code try , find value of checkbox...

foreach (entity item in checklistcollection.entities) {     checkboxid = "checkbox" + (string)item.attributes["ree_sectionnumber"].tostring() + (string)item.attributes["ree_sequencenumber"].tostring();      itemchecked = (bool)viewstate[checkboxid];      if (itemchecked == "true")         ** update database **       //checkbox checkbox = (checkbox)phchecklist.findcontrol(checkboxid); }

i think i've read every post on subject , have tried of them. have read viewstate suggestions have read have not worked. can see tried finding checkbox in controls collection id , did not work.

i not recreate checkboxes when posting page. posts mention have recreate controls when tried received error message saying duplicate id. other reason prefer not have recreate page performance hit. database in microsoft dynamic crm database remote.

how retain value of checked property across post back?

update: changed logic around , fixed duplicate id error. page recreate of controls during post back. still cannot find value of of checkbox controls when submit button clicked.

gary

you need provide id checkbox control when create it. since creating multiple checkboxes; 1 each row in database ... need add unique row identifier id. need build checkbox id row id (usually identity). example: ">

then on postback while post-processing each row in table, can query request specific key value pair. similar this:

foreach (datarow dr in datatable.rows) response["chk_" + dr("id")];
