Hi Prasanth,

It might help to explain what problems you are having and the specific version of Internet Explorer.  Is it only Internet Explorer 11?

Check the patterns page (and for OSUI) to see if the issues you are experiencing also occur there.  If the issue does not appear there, there could be something in your application causing a problem, possibly JS or CSS related.  It might also be worth creating a sample application to replicate the problem, which would help rule out any issues being caused by your application.

I am in the process of building a large enterprise application using Silk UI which must support Internet Explorer 11.  While we have found one or two small issues, for the most part Silk UI is performing well on IE 11.

This page explains that SilkUI supports Internet Explorer 8 and up, but with some limitations, though it does not say what the limitations are

https://success.outsystems.com/Documentation/SILK_UI_Framework/09_FAQs

Silk UI Web is built to support all modern browsers such as Chrome, Firefox, Edge, Safari, Opera and all modern devices such as IOS 7+, Android 4.0+ and Windows Mobile 8.1+. Internet Explorer, starting with version 8, is also supported, but with some limitations (check patterns documentation for IE8 compatibility).

Silk UI Mobile follows the same requirements as OutSystems Now, Android 4.4.2+ and IOS 8+.

For OutSystems UI, it is meant to support Internet Explorer 11, although I notice there have been some reports of compatibility issues

https://success.outsystems.com/Documentation/11/Setting_Up_OutSystems/OutSystems_system_requirements#Desktop_Browsers_(Web_applications)

Desktop Browsers (Web applications)
Internet Explorer 11 (Traditional Web Only)
Edge (latest stable version)
Firefox (latest stable version)
Google Chrome (latest stable version)
Safari (latest stable version)
Mobile Device Browsers (Web applications)
iOS 7 or higher
Android 4.1 or higher
Windows Phone 8 or higher

I hope this helps.

Kind regards,

Stuart.

Hi Prashanth,

IE is a legacy browser. Even Microsoft itself advises that you do not use Internet Explorer, but instead use Edge (if you must use MS products). Any customer that wants new functionality using an ancient browser should be asked to reconsider. Any customer wanting to use OutSystems, must be told IE compatability is limited, exactly because it is no longer a current browser.

Hi Prashanth!

Like Kilian mentioned, IE, well that's ancient and no longer supported by the manufacturer... hip hip hurray!

Stuart also gave you a pretty good and complete answer, which will possibly help. Also the a pertinent question is which IE are you aiming to support? :)

But bottom line, I'm here to complement both answers and tell you how if you reaaaaaaaallllyyyyy have to, how can you do it...

The idea: IE is an exception, as such should be dealt as such (future doesn't look bright for it... wait did I anyone mentioned that there's a future for IE?!?), this means that you should:

• create a stylesheet with all the hacks and quirks (or just the CSS that you need for IE)
• Use a JavaScript that will inject the IE stylesheet if in IE.. (if you need help I can explain how, but I think that there's gazillion of information on that) - nevertheless you can use html ifs (<!--[if IE 6]>, <!--[if IE 7]>, <!--[if IE 8]>)

And well, life's hard when you have IE, so good luck! But do let us know if you need more help.

Cheers,

RG

IE8 is plain dangerous. Any organization using is playing with fire.

If you are using a custom layout with OutSystems UI, make sure that you have referenced the LayoutWidgets webblock in the layout as this contains a nested webblock responsible for the rendering in IE called CSSVarsPonyfill (Private Flow) which changes vars to values.
