  Hello,
  
  I am currently using an IntegerTextBoxFor in a form. The form has a cancel button which calls resetForm() (actually, it calls a jquery function which calls resetForm(), amongst other things). Upon changing the value in the IntegerTextBox, the cancel button becomes enabled. Pressing the cancel button should reset the value of the IntegerTextBox.
  
  Observed behaviour: Pressing cancel does not change the value displayed in the IntegerTextBox (values in other fields of the form are reset immediately). However, the next time focus is set on the IntegerTextBox, the correct (reset) value is displayed.
  
  Is there a way to make the IntegerTextBoxFor update right away, when the cancel button is pressed?
  Thanks for any help!
  Luke
  
  Here's the code that I imagine would be relevant:
  In the View:
  

  @(Html.Telerik().IntegerTextBoxFor(m => m.Port)

      .EmptyMessage(Html.Stm(Language.MessageValueNotSet))

      .NumberGroupSeparator("")

      .HtmlAttributes(new { onkeyup = "EnableButtons()" }))

  ...

  <button type="reset" onclick="ResetForm()">@Html.Stm(Language.ButtonCancel)</button>

  
  
  The jquery function:

  // Resets the form

  function ResetForm() { 

      $('form').validate().resetForm(); 

      $(":input").hideErrorLabel(); 

      DisableButtons();

  }

  Hi Dimo,
  
  My apologies for re-surfacing this thread, but I am also getting this same error and unfortunately my code isn't stable enough at the moment to risk an upgrade. Is there any possible work-around for this bug?
  
  Best Regards,
  Landon
  
  EDIT:
  
  For anyone else experiencing this problem and is not in a position to upgrade your MVC, I've found a workaround for the solution using the Telerik API:
  
  

  var textBox = $('#NumericTextBox01').data('tTextBox');

  textBox.value(0);

  
  This works the same as if you were to set a regular input box's text() or val().

  Hello Landon,
  
  A workaround for people using older versions of our MVC components is to subscribe to the form reset event and set the NumericTextBox value via the API by using the value in the <input> element.
  
  

  // inside form reset handler

  window.setTimeout(function () {

        var ntb = $("#NumericTextBoxID").data("tTextBox);

        ntb._value(ntb.$element.val());

  }, 1);

  
  This is what the newer versions of the NumericTextBox do internally.
