c# - Why is this code executed but ignored? -

in sharepoint page, on form submission, elements revert original state (if checkbox unchecked begin, checked user, reverts unchecked, etc.).

fair enough.

but want "save state" , return sorts of things way were. 1 thing in particular visibility of dropdownlist. if visible when "save" button selected, should return being visible after form submitted; 2 dropdownlists, of @ 1 visible @ given time, start off invisible or, more specifically, "slid up" so:

$(window).load(function () {     $('[id$=ddlpaytoindividual]').hide();     $('[id$=ddlpaytovendor]').hide(); }); 

in trying save visible state of dropdownlists, i've added bools:

bool paymenttoanindividualdropdownchosen = false; bool paymenttoavendordropdownchosen = false; 

...and assign them when save button selected:

private void btnsave_click(object sender, eventargs e) {     try     {         // note current state of elements, can restored after saving/submitting         paymenttoanindividualdropdownchosen = rbpaymenttoindividual.checked;         paymenttoavendordropdownchosen = rbpaymenttovendor.checked;         . . . } 

i try set them @ end of same handler (the save button's click event) so:

if (paymenttoanindividualdropdownchosen) {     //rbpaymenttoindividual.checked = true; <= didn't work - jquery not respond programatic clicks!     ddlpaymenttoindividual.visible = true; } 

the code reached, , visible value set true (provided had made dropdown visible checking "rbpaymenttoindividual" prior selecting save button, has no effect - dropdown remains hidden.

as can deduce commented-out code, tried programatically checking radiobutton which, when done manually, sets off following client-side code:

$(document).on("click", '[id$=rbpaymenttoindividual]', function () {     if (this.checked) {         $('[id$=ddlpaytovendor]').slideup();         $('[id$=ddlpaytoindividual]').slidedown();     } }); 

...but apparently jquery not respond programatically-induced events.

or timing issue? because form still in "submit" phase/state not working -- either client-side or server-side code, or both?

if problem - submit doesn't finish until after save button handler exits, , i'm setting dropdown visible - can put code accomplish setting of form state before submit? page_load() event place and, if so, there property can interrogate determine if form has been submitted?

update

i moved code end of page_load() event, so:

if (page.ispostback)  {     if (paymenttoanindividualdropdownchosen)     {         ddlpaymenttoindividual.visible = true;     } }  

...but, because whole shebang starts fresh, paymenttoanindividualdropdownchosen's initialized value of false seen, , intentions, though good, keeping company brimstone.

so how can revert pre-submit state - .ini file, or registry usage, or cookie, usual way accomplish this?

update 2

what seems odd am able revert pre-submit state of htmltable; code in save button click handler:

// re-visiblize rows vals if (rowcontainsvals(3)) {     foapalrow3.style["display"] = "table-row"; } if (rowcontainsvals(4)) {     foapalrow4.style["display"] = "table-row"; } if (rowcontainsvals(5)) {     foapalrow5.style["display"] = "table-row"; } if (rowcontainsvals(6)) {     foapalrow6.style["display"] = "table-row"; } 

...and works fine (any rows vals displayed, although @ beginning, 1 row displays). stranger yet, perhaps, function:

private bool rowcontainsvals(int rownum) {     bool rowdirty = false;     switch (rownum)     {         case 3:             rowdirty = ((!string.isnullorempty(boxfund2.text)) ||                 (!string.isnullorempty(boxindex2.text)) ||                 (!string.isnullorempty(boxorganization2.text)) ||                 (!string.isnullorempty(boxaccount2.text)) ||                 (!string.isnullorempty(boxactivity2.text)) ||                 (!string.isnullorempty(boxamount2.text)));             break;         case 4:             rowdirty = ((!string.isnullorempty(boxfund3.text)) ||             . . . 

...finds values in input text boxes; if state of dropdownlist being visible lost during submit, why not values in textboxes/text input lost?

something rotten in redmond (or somewhere).

update 3

in response , here more code relative 2 dropdowns in question:

code-behind / c#:

rbpaymenttoindividual = new radiobutton {     cssclass = "finaff-webform-field-input",     id = "rbpaymenttoindividual" }; rbpaymenttoindividual.text = payment_or_reimbursement_to_an_individual; rbpaymenttoindividual.groupname = "paymentto"; rbpaymenttoindividual.checked = false; cellradiobutton1_1.controls.add(rbpaymenttoindividual);   rbpaymenttovendor = new radiobutton {     cssclass = "finaff-webform-field-input",     id = "rbpaymenttovendor" }; rbpaymenttovendor.text = payment_to_a_vendor; rbpaymenttovendor.groupname = "paymentto"; cellradiobutton2_1.controls.add(rbpaymenttovendor); 

rendered htm "view source":

<input id="ctl00_ctl24_g_5f3fedca_19f7_4bc3_b84e_efbef0c48a33_ctl00_rbpaymenttoindividual" type="radio" name="ctl00$ctl24$g_5f3fedca_19f7_4bc3_b84e_efbef0c48a33$ctl00$paymentto" value="rbpaymenttoindividual" />  <input id="ctl00_ctl24_g_5f3fedca_19f7_4bc3_b84e_efbef0c48a33_ctl00_rbpaymenttovendor" type="radio" name="ctl00$ctl24$g_5f3fedca_19f7_4bc3_b84e_efbef0c48a33$ctl00$paymentto" value="rbpaymenttovendor" /> 

jquery selector

:checked selector

if ($(this).is(':checked')) 

should work
