Does anyone know how to remove the close icon in the popup dialog.

Answer 1

After looking at the structure of the dialog it is easy to understand that the below CSS can be used to hide the Close button.

.ui-header > .ui-btn { display: none; }

Note this will hide all the .ui-btn in ui-header. If that is not desired, you can write a simple script to make sure that we are just hiding the Close button alone.

For all dialogs in the page:

$(function () {
    $('.ui-btn', '.ui-header').filter (function () {
        return $.trim($(this).find('span.ui-btn-text').text()) == 'Close'; 
    }).hide();
});

For any specific dialog with ID pageId:

$(function () {
    $('.ui-header .ui-btn', '#pageId').filter (function () {
        return $.trim($(this).find('span.ui-btn-text').text()) == 'Close'; 
    }).hide();
});

See below for more details about the dialog structure.

Below is the the X (close icon) as in the beginning of the div, (See complete structure)

<a href="#" class="ui-btn-left ui-btn ui-btn-up-d ui-shadow ui-btn-corner-all ui-btn-icon-notext" title="Close">
  <span class="ui-btn-inner ui-btn-corner-all">
     <span class="ui-btn-text">Close</span>
     <span class="ui-icon ui-icon-delete ui-icon-shadow">&nbsp;</span>
   </span>
 </a>
