Why wpf webbrowser generate script error? - c#

I have a site that I am trying to navigate to using wpf webbrowser. When I navigate to it, I am getting script error, but if I navigate to the same page using IE (11) on the same pc, I am not getting any error.
I supressed the script error on web browser, but then some functionality of the web site is not available when I am accessing it from wpf webbrowser.
My questions is:
Why wpf webbrowser generate script error, when IE accesses it without any error?
Is there any free alternative to webbrowser that I can use which has not this problem?

The WebBrowser control use an older version of IE.
You need to specify the IE version you want.

Loading jQuery in a C# windows form application

I'm making a Windows Form application that makes use of the browser tool. The browser does not connect to the internet and is only used to load local HTML content.
It's loading HTML CSS and JavaScript fine, but It cant seem to recognise jQuery. Is there a simple way for MVS to recognise jQuery as a script? All of the errors are related to it not understanding jQuery methods.

Webbrowser control issue with cookies

i have created web browser control in c#. I used to open .net website into this control. Once page is completely loaded.i was using cookies of this browser control to create httprequest and used to execute request. I used to get data which was needed for me.
But all of sudden this stopped working. I checkd to see what happened then i found that issues are with cookies are being formed throught browser control.For example, if i use page url on IE browser and then get cookie and supply it to httprequest. It works good. But same thing with web browser control is not working now.
Another thing, Forget about httprequest, Download from webbrowser control itselft is also failing. But its working in IE. What could be stopping it to download fail in web browser control and work in IE.
Dont understand how.please help.
This issue is not with the cookies. it is with the browser emulation. By default webbrowser control take IE emulation. but if you need to mention which browser version you want control to use. By using registry.
I emulated IE to my application by changing registry information. and it started working.

Open Website containing Javascript code

I want to open some websites which may contain javascript code for example google analytics or piwik. I think the using a webclient is the easiest way to visit websites but does the webclient run javascript code in the background automaticly or how could I get javascriptcode running by visiting a website in C#?
Have you considered using a headless browser like PhantomJS.
If you are looking for something with a UI interface, look at the WebBrowser Control.
If you need to just get the DOM or underlying elements of the DOM, I would suggest Watin. It is very mature and works well and its fast.
WebClient only loads data from the web. It does not interpret it in any way.
If you need to treat the page the way a web browser would, then you need to use a Web Browser control.
in C# there is an Internet Explorer control. You can execute javascript code on a client PC by setting web URL link to this control. Internet Explorer control is a fully functional browser which executes all client code.

Custom C# Web Browser cannot support javascript

WebKit DotNet is the best port of WebKit powerful browser engine into DotNetFramework.
It has nice and easy tutorials and properties and methods to customize.
It has JavaScript activated by default.
http://webkitdotnet.sourceforge.net/ is the official website.
http://webkitdotnet.sourceforge.net/basics.php is where you can find the basic tutorial
Webbrowser control is really crappy. I'm assuming you're trying to scape some kind of website. For this use HttpWebRequest instead.
If you`re trying create your own webbrowser: don't, or use Webkit or Gecko instead.
In case you're using the webbrowser control you will have to enable JavaScript in your Internet Explorer settings, because the webbrowser control is the Internet Explorer or at least the engine of it. IE has local JavaScript disabled by default, so this could be your problem. As user #user3855678 said I would recommend using Webkit etc too.

How to allow blocked content in an embedded Webbrowser in c#?

I'm developing a c# application that embeds the Webbrowser control. I create the Website dynamically and use NavigateToString() to display it. I'm on Windows 8 with IE10.
Now my Problem is: Javascript won't execute. For example I added a link that calls alert and another one that calls reset() on a form. Both do nothing. I believe it has to be some security issue because when I say the generated page and open the file manually in IE10 and click one of those links, I get a popup at the bottom that says "Internet Explorer restricted this Webpage from running scripts or ActiveX controls." and a "Allow blocked Content"-button. If I just Close the popup, nothing happens, if I click "Allow blocked Content" the JavaScript works fine.
How can I enable JavaScript in the embedded Webbrowser?
How are you accessing this local website? is it localhost? you need to make the url security friendly so it doesn't get blocked, give it a url http:// localhost:someport instead and it should work
