I am using ASP.NET AJAX version 2008.2.1001.20. The image manager dialogs is crashing on most PC's. The dialog popups up but just before it renders it crashes. If I click the icon a second time the popup appears ok. 
There are other PC with simlar OS and browser where it works fine all the time.
PCS that crash are running windows XP SP3 and IE 8.0.

It works the first time I visit the page but when I refresh the page and try opening the image manager again it crashes.
I ahve checked the demos that came with the installation and same issue occurs. There is not problem in firefox.

Hi HostMaster,

Version 2008.2.1001.20 is released before the appearance of IE8 and it does not support it. We provided support for IE8 in Q1 2009 SP1 (version 2009.1.402).

Please, upgrade to the latest version Q1 2010 (version 2010.1.309) of RadControls for ASP.NET AJAX which offers full support for IE8.

Best regards,

Hi Rumen,

I'd like to upgrade to version that is closest to 2008.2.1001.20 and supports IE80 as I dont want to do a full retest of my applications
that use telerik. Now am I going to have to pay full upgrade price to get this patch for my version.

Regards
Vinny

Hi Rumen,

Is it possible to get the peice of coe that fixes the popup issue and apply it to my current version. Everything works fine on IE8.0 except this issue. Also this may help, I have also discovered that if the image manager is running on a PC where the user is a administrator this isssue does not happen.

Thanks Again
Vinny

Hi Vinny,

The problem is caused by the RadFormDecorator control in the editor dialogs, which does not support IE8 in version 2008.2.1001. If you do not wish to upgrade, you can create a custom HTTP dialog handler, which inherits the default Telerik.Web.UI. DialogHandler and override the OnLoad() method, where you can try adding the

<meta http-equiv="X-UA-Compatible" content="IE=7" />

tag to the dialog page header. By default IE 8 should render all child iframes (RadWindow) in compat mode as well if the main page has the meta tag:

C# code

        protected override void OnLoad(EventArgs e)
        {
            base.OnLoad(e);
            HtmlMeta hm = new HtmlMeta();
            hm.HttpEquiv = "X-UA-Compatible";
            hm.Content = "IE=7";
            Page.Header.Controls.Add(hm); 
        }

The tags below should be also added to the web.config file:

For IIS6:
<system.web>
                ...
                <httpHandlers>
                                ...
                                <!--<add path="Telerik.Web.UI.DialogHandler.aspx" verb="*" type="Telerik.Web.UI.DialogHandler" validate="true"/>-->
                                <add path="Telerik.Web.UI.DialogHandler.aspx" verb="*" type="Telerik.Admin.IECompatibilityHandler" validate="false"/>
                                ...
                </httpHandlers>
                ...
</system.web>

For IIS7:
<system.webServer>
                ...
                <handlers>
                                ...
                                <!--<add name="DialogHandler" path="Telerik.Web.UI.DialogHandler.aspx" verb="*" type="Telerik.Web.UI.DialogHandler"/>-->
                                <add name="Telerik.Web.UI.DialogHandler.aspx" path="Telerik.Web.UI.DialogHandler.aspx" verb="*"                                 type="Telerik.Admin.IECompatibilityHandler" />
                                ...
                </handlers>
                ...
</system.webServer>

All the best,
