Telerik injecting javascript after each ajax update

[Martin]

Hi,

I have an Ajax page which has a number of Telerik controls on it.

It would appear that each Ajax response is including some inline script:

if (typeof($telerik) != 'undefined' && !$telerik.isSafari)
{
    var links = document.body.getElementsByTagName('link');
    if (links && links.length>0)
    {
        var documentHead = document.getElementsByTagName('head')[0];
        if (documentHead)
        {
            for (var i=links.length-1;i>=0;i--)
            {
                var linkTag = links[i];
                if (linkTag.title == 'Telerik stylesheet')
                {
                    if ($telerik.isIE)
                    {
                        linkTag = linkTag.cloneNode(true);
                    }
                    documentHead.appendChild(linkTag);
                }
            }
        }
    }
}

Is it possible to turn this off? Is it possible to have a function call instead? My concern is that performance is degrading and the DOM is forever getting larger.

Thanks,
Martin

Hello Martin,

Please update your project with a more recent version of the RadControls for ASP.NET AJAX. I think this problem was fixed in the Q2 2008 release. If you do not wish to upgrade at this time, then you can workaround this problem by manually setting the EnableAjaxSkinRendering property of all RadControls on the page to false.

Kind regards,

Hi Lini,

I have upgraded and now using version 2008.2.826.35 of Telerik.UI.dll. The javascript is still injected, allbeit written out slightly differently.

It is not proving to be a performance problem right now, so am ignoring it.

Just as a note, upgrading has meant that my version of the Office Ribbon Bar taken from your site, now renders quite differently!

Thanks,
Martin

Hello Martin,

This script is sent during an Ajax request if the following two conditions are met:

- you are updating at least one of the RadControls.
- the control has its EnableAjaxSkinRendering property set to true. This can happen if the control was dynamically added during the Ajax request, its ViewState is disabled, or it was initially hidden and was made visible.

If all RadControls on the page have EnableAjaxSkinRendering set to false, the script will not be used. Its purpose is to load the control skins in the page header, which ensures that the controls will display correctly.

Best wishes,
