Preventing a User from Altering a DropDownList Selection with JavaScript in ASP.NET

Hey there, I'm working with a dropdown list where the values are selected from server side code. I'm looking to prevent users from changing the selection either by clicking with the mouse or using the keyboard. I'd like to handle this restriction on the client side. I appreciate suggestions for JavaScript methods only.

Answer №1

Give it a shot:

Using Jquery:

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

OR

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

Or, with Javascript:

To disable an Asp.net DropDownList using JavaScript on the client side, you can use the following code.

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

Edit:

To implement this code, place it within either the head tag or body tag.

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

I trust that this will be of assistance to you.
