HtmlPlaceHolder +out of browser +script bundling

[leblanc]

We have a RadWindow hosting a RadHtmlPlaceholder for the login screen:
https://gg.improvingrestaurants.com/

if you go the website and review the script errors you will notice there are None.


If you install locally the out of browser version and open the app - it shows script errors.
This happened once we migrated to script bundling.

Why does it have a problem out of browser but not when running in the browser?  What is the implementation difference of
HtmlPlaceHolder?

Thanks,

It looks like it is the WebBrowser using IE7 .

Is there anyway to suppress the error or workaround recommended?

Hi leblanc,
The implementation difference in the RadHtmlPlaceholder is that in out-of-browser applications it uses the Microsoft WebBrowser control and in browser it uses an IFrame. As far as I understand the issue is that by default the WebBrowser renders pages in IE7 standards mode. The easiest fix/workaround that I found is to add an "x-ua-compatible" attribute to your page:

<meta http-equiv="x-ua-compatible" content="Edge" />

or

<meta http-equiv="x-ua-compatible" content="IE-9" />

You can read more about this attributes here, here and here.
I hope I was able to help you and if you have more questions please feel free to ask.

Regards,
