Hi,
whilst the Grid is loading I get FOUC (Flash of Unstyled Content on the Menu component.
My only solution for this was the following in the HTML code: see green
<head runat="server">
<title></title>
<style type="text/css">
.no-fouc {display: none;}
</style>
<link rel='nofollow' href="Content/ej/ej.widgets.core.min.css" rel="stylesheet" />
<link rel='nofollow' href="Content/ej/default-theme/ej.theme.min.css" rel="stylesheet" />
<script type="text/javascript" src="Scripts/jquery-3.1.1.min.js"></script>
<script type="text/javascript" src="Scripts/jsrender.min.js"></script>
<script type="text/javascript" src="Scripts/ej.web.all.min.js"></script>
<script type="text/javascript" src="Scripts/ej.webform.min.js"></script>
<script>
$(document).ready(function () { $('.no-fouc').removeClass('no-fouc') });
</script>
<script type="text/javascript">
document.documentElement.className = 'no-fouc';
</script>
<asp:ContentPlaceHolder ID="head" runat="server">
</asp:ContentPlaceHolder>
<style type="text/css">
.auto-style1 {
width: 100%;
}
</style>
</head>
