Hi There,

The RadBinaryImage in our application works well until Firefox upgraded to 43.0.1. Now the problem I am facing is that the image does not show unless I click or move the mouse on the page. I also noticed this issue only happens on gif files, not on jpeg files.

Here is the scenario: two pages included in this test demo, the first page has a linkbutton to open a radwindow, the second page is the RadBinaryImage to display a image file.

The following is my test code, please help, thank you.

Default.aspx:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="RadBinaryImageDefault.aspx.cs" Inherits="Default" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

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

<script type="text/javascript">

function ShowWindow() {

window.radopen("RadBinaryImageTest.aspx", "RadTestWindow");

return false;

}

</script>

</telerik:RadCodeBlock>

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="true">

<Windows>

<telerik:RadWindow ID="RadTestWindow" runat="server" Title="Rad Binary Image" Height="500px"

Width="500px" Left="150px" ReloadOnShow="true" ShowContentDuringLoad="false" AutoSize="false"

Behaviors="Pin, Move, close, Resize" Modal="true" />

</Windows>

</telerik:RadWindowManager>

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

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

</asp:ScriptManager>

<div>

<asp:LinkButton ID="lbl_click" runat="server" Text='Click' OnClientClick="return ShowWindow();" Visible="true"/>

</div>

</form>

</body>

</html>

RadBinaryImageTest.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="RadBinaryImageTest.aspx.cs" Inherits="RadBinaryImageTest" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

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

<div>

<telerik:RadBinaryImage runat="server" ID="rbi_thumbnail" AutoAdjustImageControlSize="false"/>

</div>

</form>

</body>

</html>

RadBinaryImageTest.aspx.cs

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Drawing.Imaging;

using System.IO;

using System.Drawing;

public partial class RadBinaryImageTest : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

DisplayThumbnail();

}

public void DisplayThumbnail()

{

rbi_thumbnail.DataValue = ImageToBinary("../../index.gif");

}

public static byte[] ImageToBinary(string imagePath)

{

FileStream fileStream = new FileStream(imagePath, FileMode.Open, FileAccess.Read);

byte[] buffer = new byte[fileStream.Length];

fileStream.Read(buffer, 0, (int)fileStream.Length);

fileStream.Close();

return buffer;

}

Hi Don,

I have tested the exact scenario that you have with our latest version and after the automatic upgrade of Firefox (it upgraded to a beta version - 44.0b1) and everything is working correctly on my end with gif images. With that in mind I could only assume that this is some browser issue, related with the rendering engine of the browser, which is resolved in newer versions.

Hi Don,

I have tested the same example with Firefox version 44.0 with the attached gif file, but everything is working correctly on my side. You could try with the attached gif file and see if the issue is replicated with it.

However, please keep in mind that this is a browser issue and there is nothing that could be done on our side to resolve it.
