Issue with setting hidden field in asp.net winforms using jquery

I have some code to set the value of a hidden field so I can access it in the code behind but the value is always empty in the code behind. The value for the effectiveDate is being set but I doesn't look like the hidden field property Value is being set.
<input id="appEffectiveDate" type="text" />
<label id="effectiveDateLabel" for="appEffectiveDate">App Effective Date</label>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<asp:HiddenField ID="appEffectiveDateToSetForUserRole" runat="server" Value="" Visible="false" />
<script>
$(function () {
var SelectedDates = {};
$('#appEffectiveDate').datepicker({
beforeShowDay: function (date) {
var Highlight = SelectedDates[date];
if (Highlight) {
return [true, "Highlighted", Highlight];
}
else {
return [true, '', ''];
}
}
});
$("#effectiveDateLabel").hide();
$("#appEffectiveDate").hide();
$('input[value="85"]').click(function () {
if($(this).is(':checked'))
{
$("#effectiveDateLabel").show();
$("#appEffectiveDate").show();
}
});
$("#appEffectiveDate").change(function () {
var effectiveDate = $("#appEffectiveDate").val();
$(":asp(appEffectiveDateToSetForUserRole)").prop('value', effectiveDate);
});
});
</script>
In the code behind the value is empty for the hidden field:
if (!string.IsNullOrEmpty(appEffectiveDateToSetForUserRole.Value))
{
// this is never called because .Value is empty
}

If Visible is set to false, the control will not be rendered by ASP.NET in the markup at all, which means that jQuery won't be able to find it because it doesn't exist. Just remove the visible=false part. It'll stay hidden.

Grab Gridview textbox input value Jquery

I have built the following Gridview (Employees and their weekly target):
Desired result: I have a submit button at the bottom which will take all the data from the Gridview using jQuery and push it into my database.
At the moment, I cannot even retrieve the textbox values though, i have the following code:
$(document).ready(function () {
$("#btnSubmit").click(function () {
$("#GridView1 td").each(function () {
var value = $(this).text();
alert(value);
});
});
});
This Selects all the "Table Data" cells... It is selecting the names perfectly, but as soon as it gets to a textbox, it doesnt get the value I type in, it just alerts nothing.
I have tried the following too, each with different, but not the desired results:
.html
.val
.innerHTML
Would anyone be able to point out where I am going wrong please? please let me know if you need anymore info...

You have to check if the control exists in the table cells or not
Give this a try
var value = $(this).find('input').length > 0 ? $(this).find('input').val() : $(this).text();
Hope this will work!

You must select the input textbox in your selection as given below
$(document).ready(function () {
$("#btnSubmit").click(function () {
$("#GridView1 td input").each(function () {
var value = $(this).val();
alert(value);
});
});
});

How to get hidden field value code behind updated by jquery/javascript

I have an <asp:menu/> control and a hidden field.Now i am using jQuery to change value of hidden field.
Code is:-
$(function() {
$(".primaryStaticMenu tr,td").each(function(index) {
$(this).click(function() {
if ($(this).attr("title") != "undefined"
&& $(this).attr("title").length > 0) {
document.getElementById('ctl00_Hidden_Master_Location').value = $(this).attr("title");
alert(document.getElementById('ctl00_Hidden_Master_Location').value);
//return false;
}
});
});
});
Server side code to get updated value is:-
string Get_cng_value = Hidden_Master_Location.Value;
But Hidden_Master_Location.Value shows null every time.
can any one tell me how to get updated value of hidden field from code behind.

Let say your hidden field is as..
<asp:HiddenField ID="Hidden_Master_Location" runat="server" />
you can get the value of hidden filed in jquery as
var locationValue= $("#<%= Hidden_Master_Location.ClientID %>").val();

Do this, it works for me.the trick is to save your hidden field precious id in another hidden input field then build it back using that hidden value.
Markup
<asp:HiddenField ID="HiddenFieldMaster" runat="server" />
<input type="hidden" id="inputHidden" value='<%= HiddenFieldMaster.ClientID%>' />
Javascript
$(function() {
$(".primaryStaticMenu tr,td").each(function(index) {
$(this).click(function() {
if ($(this).attr("title") != "undefined"
&& $(this).attr("title").length > 0) {
var inputHidden = document.getElementById('inputHidden');
$("#" + inputHidden.value).val($(this).attr("title"));
alert(inputHidden.value);
//return false;
}
});
});
});
Code Behind
String Get_cng_value = HiddenFieldMaster.Value;

Required textbox in javascript

I have this code
$(document).ready(function () {
$("#<%= chkSpecialIntegration.ClientID %>").click(function () {
if (this.checked) {
document.getElementById('<%=ddlTypeSpecialIntegration.ClientID %>').style.visibility = 'visible'; }
});
});
When this is checked then a textbox is no longer required. How can I do this?

If all you want to do is make ddlTypeSpecialIntegrationvisible when chkSpecialIntegration is checked, you can just do:
$(document).ready(function () {
$("#<%= chkSpecialIntegration.ClientID %>").toggle(function() {
$("#<%= ddlTypeSpecialIntegration.ClientID %>").show();
}, function() {
$("#<%= ddlTypeSpecialIntegration.ClientID %>").hide();
});
});

There are two ways that an html textbox can be forced to be required. You should implement both.
The first is to validate the data prior to form submission. You can accomplish this in javascript by hooking into the onsubmit event. An example is at http://www.w3schools.com/js/js_form_validation.asp
Inside that method you will need to test if your checkbox is selected or not. If it isn't, then see if they typed something in your textbox.
The second is to validate it server side after form submission. For this you could simply provide some validation code in your button's server side onclick method.
I say to implement both because you will want to provide immediate feedback when something is required client side and you want to enforce it server side in case javascript is turned off.
Of course, if JS is turned off then they will probably never see the textbox to begin with.

Why do you need JS for that?
Isn't something like this enough?
<input<% if some_condition %> required="required"<% endif %> name="field" />

Give id for textbox like
<%: Html.TextBoxFor(model => model.FirstName, new { #tabindex = "1", maxlength = "50" ,id="Name"})%>
$(document).ready(function () {
$("#<%= chkSpecialIntegration.ClientID %>").click(function () {
if (this.checked) {
document.getElementById('<%=ddlTypeSpecialIntegration.ClientID %>').style.visibility = 'visible';
$("#Name").hide;
}
});
});
