How to block User from changing DropDownList value using javascript in asp.net?

Question

Hi I have a dropdownlist, I am selecting its valus from server side code. I don't want to allow user to change it. Means He must not be able to change it neither by mouse click and not by keyboard. I want to handle it from Client Side. Please suggest only javascript methods.

Just disable the dropdown from client side. – Usman Khalid Feb 26 '14 at 11:07 — Usman Khalid, Feb 26 '14 at 11:07

Try it:

Jquery:

 $(document).ready(function() {
      $("#dropdounid").prop("disabled", true);
 });

OR

 $(document).ready(function() {
      $("#dropdounid").attr("disabled", true);
 });

OR

Javascript

you can disable Asp.net DropDownList using below code in javascript at client side.

document.getElementById('<%=txtActualWindSpeed.ClientID%>').disabled = true;

Edit

you can put this code inside of head tag or body tag.

<head>
  <script>
     document.getElementById('<%=txtActualWindSpeed.ClientID%>').disabled = true;
  </script>
</head>

I hope it will helpful to you.

for which client side event I should write this piece of code. This is big concern for me. – user3264676 Feb 26 '14 at 11:35
if you don't want to allow user to change `dropdown` then you can keep this code in your source code `` – Govinda Rajbhar Feb 26 '14 at 11:38
