Question

I Have a hidden field that contains a value and my code block within view (within @{} ) requires the same . I have tried a lot of formats trying to use jquery with @: etc. but non of them work.

so basically if i have a hidden field with ID=”aField” having a value, I will require the value of it somehow on to my say a string variable.

@{ string hiddenValue = //Value from that hidden field }

Thanks,
Anand

UPDATE :

The value onto hidden field is populated on some client actions using Jquery and is required before form submit. Hence I am not using view bag . Am i mistaken or missing something ?

hence i am looking for a way to may be if possible use jquery to read back the updated value and use it .

tried a lot to include jquery within the above shown code block to get the value but always end up in errors.

UPDATE 2:

Implemented the suggestion by Shoib (thanks for that) to use Ajax and update the same in viewbag and use it for my requirement, also with break points I see that ViewBag has updated value that I am using in my form.

the next thing i am stumbled up is , on browser still i do not see the value selected . it just displayes old value. Is my update lost during rendering / is it just rendering old HTML ? Any help appreciated

below is my script. server side i just update ViewBAg property with this value that works confirmed.

  function setHiddenFieldValue(buttonEditClicked)
    {



    $('#contactIdHiddenFld').val("");

    $('#contactIdHiddenFld').val(buttonEditClicked.title) ;
    alert($('#contactIdHiddenFld').val());


    $.ajax({         
        url: "@Url.Action("SetPartnerProfileContactID", "PartnerManagement")",         
        data: {partnerContactID: $("#contactIdHiddenFld").val()},         
        dataType: 'html', 
        cache: false,        
        type: "POST",         
        error: function() {             
            alert("An error occurred.");         
        },         
        success: function(result) {             
    jQuery.validator.unobtrusive.parse('EditContactForm');
    Sys.Mvc.FormContext._Application_Load();

          var windowElement = $('#EditContactWindow');         
      windowElement.data('tWindow').center().open();

        }     
    }); 

Also here is a snippet of the form .

@using (Html.BeginForm("GetProfile", "PeopleManagement", FormMethod.Post, new { id = "EditContactForm" }))
{
    <p class="note">
        Please Enter the contact details below</p>


    <table border="0" cellpadding="0" cellspacing="0" id="EditContactsTable">

        @{                
            string toCheck = ViewBag.ContactIDToEdit;
            int count = (from n in Model.PartnerDetails.Contacts where n.PrimaryContactId==toCheck select n).Count();

         }

        <tr>
            <td class="table_label_cell" width="20%" >
                <font color="red">*</font><label for="firstname">@ViewResources.PartnerManagement.GetPartnerProfile.FirstName :</label>
            </td>
            <td class="table_value_cell" width="40%">                   
                @Html.TextBoxFor(m => m.PartnerDetails.Contacts[count].PrimaryContacts.FirstName)

            </td>
            <td class="table_value_cell" width="40%">
                @Html.ValidationMessageFor(e => e.PartnerDetails.Contacts[count].PrimaryContacts.FirstName)
            </td>
        </tr>
        <tr>
            <td class="table_label_cell" width="20%">
                <font color="red">*</font><label for="lastname">@ViewResources.PartnerManagement.GetPartnerProfile.LastName :</label>
            </td>
            <td class="table_value_cell" width="40%">
                 @Html.TextBoxFor(m => m.PartnerDetails.Contacts[count].PrimaryContacts.LastName)
            </td>
            <td class="table_value_cell" width="40%">
                @Html.ValidationMessageFor(e => e.PartnerDetails.Contacts[count].PrimaryContacts.LastName)
            </td>
        </tr>

Answer 1

public ActionResult Index()
        {
            ViewBag.Message = "Welcome to ASP.NET MVC!";
            ViewBag.hfMyField = Request.Form["hfMyField"];
            return View();
        }

this way you can access it in view.

 <h4>@ViewBag.hfMyField</h4>
