I'm using WebBrowser control in .NET app. I construct a html text, then set the controls property DocumentText to this html. It works fine on my computer. On some other computers it simply displays the source as a text. I think that it may be connected with some explorer properties but I don't really know why it is behaving like this. How can I handle it to always display proper view? Or at least what can I fix on a specific computer so that the application works fine/
There is allways the sucky way of dumping the HTML to disk and set the URL to the file. But that is not a good solution.

I´m wondering if it could be possible to change the HTML document text directly from the web Browser.
I´m currently working on an email client, which uses a html template for the design.
Everything seems good but I need to configure the template.
Like I said, the template is stored in a rich textbox, which is invisible.
Basically I can see the web Browser with its template, only.
Now I want to insert my custom text to the template.
Is it possible to change the htmldocumenttext directly from the webbrowser ?
Is there another way to edit the content of the template ?
You bet it's possible. Whole libraries are written around modifying the HTML after initial delivery to the browser. Start here: http://www.w3schools.com/js/js_htmldom.asp. Then maybe: https://jquery.com/
I want to display a webpage in a WebBroswer in my winforms application. I however want to use some custom css to change how the page looks. Is it possible to attach a style sheet and edit the html page you are viewing?
You can use this web control http://www.codeproject.com/KB/miscctrl/csEXWB.aspx
and save it as a web page and load and you can show the source in another text box , once changes are made you can save to a temp file and load it. There is an option to view local file.
I don't think that kind of thing is supported.. but anyway that would be a horrible thing to do. you may end-up interfering with the CSS used by the client page.
Have you ever seen your browser override your CSS used by page and say i want to show it this way. (I know development tools like firebug,etc do it)
I need to display HTML in my silverlight application and cannot find a way of doing it. I cannot use the web browser control as it needs to be able to run in or out of a browser.
Does anyone know of a good way to do this, because all I can think of doing at the moment is running replace methods on the text to just replace the tags with C# equivalents eg(<br /> to \n).
The way I do it is to check if the application is running inside the browser and change the means of display accordingly. If running inside the browser, I overlay the application with an IFrame, as I describe in this article: http://www.silverlightshow.net/items/Building-a-Silverlight-Line-Of-Business-Application-Part-6.aspx. Otherwise, I use the WebBrowser control. I have a control which does this all for you in the source code that accompanies my book, which is downloadable from the Apress website here: http://www.apress.com/book/downloadfile/4638.
Hope this helps...

I believe what you are looking for is HTML Bridge.
Edit I'm am actually now unsure if you'll still have access to javascript if you're running this OOB. I'm going to look into this some more and will further update. I'll still leave the answer up though for reference.
Second Edit Here is what I've found. HTML Bridge is disabled when you run silverlight out of browser. This disables access to the HTML DOM as well as Javascript. However, according to a comment on this site:
HTML Bridge is not available when you first install a OOB app. But you CAN force it if you modify the index.html in the folder where the app is installed just adding the enablehtmlaccess parameter.
It works!
You can even create dynamic HTML elements using the well-known methods of the HtmlPage class. You can even open a new browser window with the Navigate() method and its "_blank" parameter.
Keep in mind this information was posted about SL 3. Its possible that this may have changed, but I doubt it. So it seems that what you may want to do is build a script into the startup of your SL app that detects whether or not your app is running out of browser. If it is then you may want to have some script to call that can modify this file for you.
There recently was a similar question.
I posted a link there to an implementation that parses and displays HTML inline in Silverlight. Of course, it will work only with simple HTML, but maybe you can expand it to your needs.
I am working with .net c#.
Is there a way to see the rendered html code under the updatepanel?
Thanks
more info:
I dynamically generate UI controls and place them in a asp:Panel control I have under updatePanel. My page is initially almost empty, and I add about 50 new controls upon button click. However, I cannot see the html code generated in the page source. as in, I can see my textfield on the screen but I cannot see the corresponding code in the html source on my browser.
Thanks again.
What are you using to view the source? If you are using the View Source functionality in some browsers, this may only be showing you the initial server response, and anything dynamically inserted into the page in an AJAX call might not appear.
If you use a tool like Firebug you can watch the current state of the DOM, which will show you any dynamically inserted elements.
With Internet Explorer you can use the Developer Tools (IE8) to view the actual source, not just the initial source. As Tom said Firebug will do the same thing in Firefox, and Safari has a similar option that I can't remember off hand what it's called.
Basically, you need to inspect the DOM instead of the html source. Addins like Firebug for firefox and Developer Tools for IE8 would allow you to inspect the DOM and even allow you to update them dynamically.
If you need to view HTML instead of the DOM representation, you can use Fiddler or Firebug's NET Panel, which will let you debug HTTP traffic and see the response given for the AJAX calls.
It does appear over here, just like normal ASP.net controls, just there is a little bit of ajax code that does the updating. Can you be more specific about what are you looking for?
This is a bit special:
I'm loading some HTML in string form into the WebBrowser control via the DocumentText property.
Now when I print the page with a PDF printer (Bullzip PDF Printer in my case) it always takes the URL as document name which is "about:blank".
Is there any way to change this to another value by either changing the URL property (it's read-only) or by changing the print behaviour to use another text rather than the URL as filename?
There are a couple of options that I am aware of though my knowledge on this subject is a bit dated.
The first is to change the computer settings in Internet Options. Regardless of whether this is done by hand or through a registry change script, it is simple for the developer, but obviously not the best approach from the deployment or compatibility angles.
The next approach is to develop a custom print template. This is not fun, but is probably the most professional approach. As much as I would love to include all of the information needed on this approach in this post, it is too much to cover. Here is a good overview and good luck Googling from there.
My experience with this involved printing from the MS WebControl component used in a .NET 1.1 Winforms application to the Web Super Goo PDF converter component. Your mileage may vary.
You can change the header and footer such that the URL property is not printed.
Try to Navigate to a URL, then cancel that via DWebBrowserEvents::BeforeNavigate
