Tetbox value not getting updated?

I have an asp.net textbox which is disabled and I am setting the value for the te开发者_JAVA百科xtbox on client side using JQuery.

$('[id$=txtCity]').val('Naperville');

But the problem is when I am trying to save the data. If I say txtCity.Text it is not giving me the value that I set in the client side.

The textbox is disabled and I am seeing the value reflected in the textbox on the client side after the value is set using JQuery. But I am not sure why it is not reflected on the server side.

I found that TextBox with disabled will not be submitted with the form on postback. If that is true, how can I submit those values and get that on server side in the code behind.

Please help. Thanks and appreciate your feedback.

You can always "un-disable" the field before posting. E.g.,

$('form').submit(function() {
  $(this).find(':input:disabled').removeAttr('disabled');
});

And of course using readonly fields, as per Knix's answer, may be a viable solution as well.

Edit: just read your comment on Knix's answer, so it sounds like dynamically removing the disabled attribute before posting may be the way to go.

I don't think disabled fields will get posted.

Maybe you should try readonly field: http://www.w3schools.com/tags/att_input_readonly.asp

<input id="firstName" name="firstName" value="hello world" READONLY>

You can always use CSS to make the readonly field appear disabled =)

EDIT:

Ok..if you cannot do the readonly, how about using AJAX to post and directly passing over the data since you say you can access it on the client side:

$.ajax({
      url: "yourForm.php",  // sorry I used PHP in this example 
      type: "POST",
      data: { txtCity : $('#txtCity').val() },
      success: function(msg){
         alert(msg);
      }
   }
)

EDIT2:

How about populating a hidden field and using that value on the server-side since you cannot use readonly fields or use AJAX?

$('#hiddenField').val('Naperville');

Since this field is hidden, the user would not know the difference =)

EDIT3:

OP got this to work using correct server-side syntax for the readonly inputs:

TextBox1.Attributes.Add("readonly","readonly")
