I have a full license, and the datepicker seems to work correctly, but it displays a button instead of the calendar icon. I have compared my code to the demo and cannot find the issue.

You can view the problem here: http://sonoma-dev.webreliance.com/grid_orderattachments.php?id=DF53D7BC-6AF6-4E88-811C-C223B821CCA0

Click to add a record and you'll see the form shows a Calendar button instead of the icon.

Here is my php code:

<?php include '_db.php' ?>

<?php
// include and create object
include("lib/inc/jqgrid_dist.php");
$g = new jqgrid($db_conf);

// set few params
$grid["caption"] = "asdf";
$grid["autowidth"] = true;
$grid["height"] = "175";
$grid["form"]["position"] = "center"; // position form dialog to center
$grid["form"]["nav"] = true; // show form navigation
$grid["export"] = array("format"=>"pdf", "filename"=>"my-file", "heading"=>"Invoice Details", "orientation"=>"landscape", "paper"=>"a4");
$grid["add_options"]["jqModal"] = false;
$grid["edit_options"]["jqModal"] = false;
$g->set_options($grid);

$g->set_actions(array(
"add"=>true, // allow/disallow add
"edit"=>true, // allow/disallow edit
"delete"=>true, // allow/disallow delete
"rowactions"=>true, // show/hide row wise edit/del/save option

);
//$g->set_actions(array("delete"=>true, "add"=>true, "edit"=>true));

// set database table for CRUD operations
$g->table = "data_Attachment";

// subqueries are also supported now (v1.2)
$orderguid = $_GET["id"];
$orderid = GetOrderID(&$dbhandle, $orderguid);
$sql = "select attachmentguid, orderid, attachdate, description, origfilename, filename, createuser, modifyuser, modifydate from data_Attachment where orderid = '" . $orderid . "' ";
