Hi Anders,

The reason for the problem is that WebKit-based browsers are loading the resources slower (the CSS and the images are coming from the resource axd file) than the other browsers.
In this case I could suggest 2 approaches. The first one is to manually insert the CSS for the Window from the resources - check the RadCodeBlock in the sample below. Note that you must make sure that you are using the corresponding skin.
Approach #2 is to use a "dummy" RadWindow that has VisibleOnPageLoad=true, but will be shown outside the viewport. You can close the window in the OnClientShow event handler.

<head runat="server">

<title></title>

<%--

Approach#1 - use the following link references - make sure that the skin's name matches (in the code below we are using the Default skin

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<link href='<%= Page.ClientScript.GetWebResourceUrl(typeof(RadWindow), "Telerik.Web.UI.Skins.Window.css") %>'

rel="stylesheet" type="text/css" />

<link href='<%= Page.ClientScript.GetWebResourceUrl(typeof(RadWindow), "Telerik.Web.UI.Skins.Default.Window.Default.css") %>'

rel="stylesheet" type="text/css" />

</telerik:RadCodeBlock>--%>

</head>

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="Sc1" runat="server">

</asp:ScriptManager>

<telerik:RadWindowManager ID="radWindowManager" runat="server">

<Windows>

<%-- Approach #2 - use a "dummy" RadWindow that will be shown outside the viewport and closed after that in OnClientShow --%>

<telerik:RadWindow ID="dummyWin" runat="server" OnClientShow="OnClientShow" VisibleOnPageLoad="true"

Top="-10000" Left="-10000">

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

<button runat="server" onclick="openWin();">

test</button>

<script type="text/javascript">

function openWin() {

radopen("about:blank", "RadWindow1");

}

function OnClientShow(sender, args) {

sender.close();

}

</script>

I hope this helps.

Hi Anders,

I see that my previous reply is not complete enough so I just wanted to provide more info on the subject. It is not that the WebKit's browser loads the images slower, they simply load everything else (scripts / elements / texts) much faster that the images which leads to the behavior that you experience. We are currently investigating possible approaches for this case, but we'll need more time for research.
