my js:

C#

function confirmDelete() {
           
                       var lang = document.getElementById('idlang');
                      if (lang.value == 'Germany') {

                           return confirm('GErmany message');
                     } else {
                          return confirm('English');

Solution 2

Try changing this line:

JavaScript

var lang = document.getElementById('idlang');

to this:

JavaScript

var lang = document.getElementById("<%= idlang.ClientID %>");

hope it helps :)

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
