Change text in Date Picker Button or display an image

To style the Date Picker button to display an image instead of the default "..." edit the following file;

/includes/wdg/Calendar,js

Search for this block of code:

var btnAttributes = {
   "type":"button",
   "name":boundTo+"_btn",
   "id":boundTo+"_btn",
   "value":paramObj.label
};

Change to:

var btnAttributes = {
   "type":"image",
   "src":"../../../images/calendar.png",
   "width":"24",
   "style":"vertical-align:bottom",
   "name":boundTo+"_btn",
   "id":boundTo+"_btn",
   "value":paramObj.label
};

To change the default "..." into some text edit the following file:

/includes/resources/WDG.res.php

Change Line 9 from

'calendar_button' => '...',

to

'calendar_button' => 'Select Date',
