I have some XML in an XmlDocument, and I want to display it on an ASP.NET page. (The XML should be in a control; the page will have other content.) Right now, we're using the Xml control for that. Trouble is, the XML displays with no indentation. Ugly.
It appears that I'm supposed to create an XSLT for it, but that seems kind of boring. I'd rather just throw it into a control and have it automagically parse the XML and indent correctly. Is there an easy way to do that?
You could try to use XmlWriter/XmlTextWriter, set the writer's Indentation property, write to a StringBuilder or MemoryStream, and output the result inside a <pre> tag
A quick (and dirty) way of doing this would be to use an IFrame.
In truth, an XSLT is the "ideal" way for formatting an XML for display. Another option would be to parse it manually for display.
To use an Iframe:
ASPX side:
< iframe runat="server" id="myXMLFrame" src="~/MyXmlFile.xml" /></pre>
Code Side:
myXMLFrame.src = Page.ResolveClientUrl("~/MyXmlFile.xml")
You can find a slightly modified version of the XSLT that IE uses to transform XML to HTML when viewing in IE at http://www.dpawson.co.uk/xsl/sect4/N10301.html#d15977e117.
I have used it in a WebBrowser control in a WinForms application, and it works lika a charm. I have not tested it in FireFox/Chrome/Safari/Operat, though.

So I am using SelectPDF to convert an MVC view's html to PDF, but for some reason, a great deal of the content is missing from the PDF.
I have tested the program on other sites I have made in MVC and they work...
So as per the readme doc's recommendation, I use this code to produce a
SelectPdf.HtmlToPdf converter = new SelectPdf.HtmlToPdf();
SelectPdf.PdfDocument doc = converter.ConvertUrl(HTMLPath);
//SelectPdf.PdfDocument doc = converter.ConvertHtmlString(ViewHTML);
doc.Save(PDFSavePath);
doc.Close();
So HTMLSave path is the location of the HTML file created from the rendered MVC view. While ViewHTML contains the HTML in the form of a string.
So this is how the HTML looks (the file and the view look identical, I did double check in case the HTML was captured incorrectly):
But this is how the PDF looks:
Absolutely tragic...
Not sure if it will be helpful, but here's the HTML:
https://drive.google.com/open?id=0B8DiACLG11oYd3p5Tzc2ZlJQLVk
Unfortunately, all the HTML is on one line thanks to the MVC View to HTML
It seems that the html/css engine used to render the page does not support vh, vw for font sizes. It's a common issue with all converters, so probably you should try to change this if you need the page converted to pdf.
Later update: it seems that there is support for vw, but not for vh. That's why the "each" words appear. They use vw in css.
I see a similar case which answer my question in JQuery way:
Remove tag but leave contents - jQuery/Javascript
But I need to know how C# works for this? Is there any API in C# that I can use to strip out the tag and leave the plane text?
From:
some content and more and more content

Use HtmlAgilityPack ( http://htmlagilitypack.codeplex.com/ ), load your HTML document into a HtmlDocument instance and query document.DocumentNode.InnerText.
I am trying to create a program / service that can read an html file and print it.
I need to include page breaks; but don't know how to define them or make them print correctly.
The html files are mine, so I can add any elements to them to represent the page break position. I was thinking a hidden field, or using the page-break-before:always css style in the next element.
How should I approach this?
Css is the way to go. I'd recommend to create a class "page-break":
.page-break { page-break-before: always; }
Whereever you add this class to an HTML-element you get a page-break before this element (e.g. before every h1).
This tutorial covers almost every part of CSS and printing:

hope this helps
We're displaying objects within a web-page which have basic height and width properties. We can generate the HTML objects utilising the HtmlTextWriter object and plan to apply the Height and Width properties by referencing the object's ID in embedded css class at the top of the class.
#bob
{
height: 20
width: 20
}
...
<div id="bob"></div>
1) Firstly, is this a good approach or should we be considering another approach like inline css ?
2) There doesn't appear to be anything written in the surrort of rendering css within the .net framework. Does anyone know of anything which might be of assistance in rendering css notation with the .net framework. Is there an equivalent to HtmlTextWriter ?
3) Do you know of any tools which can be of assistance in generating css from code ?
Kind Regards
Not sure if you can do it in .net. But I am doing it in jquery as below. I hope this is someway useful.
$.rule("#bob {height:"+ht+"}").appendTo('style');
When this is generated then you can check in your dom that some css has been added to style element.
It is better than inline css. It works for the webpage which is displayed on the browser and not physically written to the file.
More info - here
It works in IE8, FF and Chrome when I checked.
Why are you writing out HTML, does one of the existing controls not provide what you need?
In general, CSS should be in a .css file.
It's not really possible to answer if this is a good approach since you haven't explained the intent of the code.
Try almost not to use inline css and you can use a literal that has the css string in it, and let the htmlTextWriter write it.
I have tried to use the standard AJAX HTMLeditor from here (http://www.asp.net/ajaxlibrary/act.ashx) and I have try to work with the FCKEditor (from http://ckeditor.com/)
But both don't do everything. I call the AJAX standard control A and the FCKeditor F.
With the A editor it is impossible to get your HTML text in the HTML content. You can only get it in the Design content. (this next code doesn't do the job: string htmlContentStr = Editor1.Content).
With F it is possible to get it in the HTML content (it does this by default), but to get your changes back in HTML is impossible. (this next code doesn't do the job: string htmlContentStr = FCKeditor1.Value).
So what I need is a HTML editor that is possible to put HTML text in HTML content, a user can make changes in the designcontent and after the changes 're make it must be possible to get the HTMLcontent and put it away in a string or database.
Is this possible or do I need a commercial one to get this feature?
If my question isn't clear, please let me know.
Thnx
I've used XStandard quite easily and it let me manipulate the HTML. I didn't bother using it as a control, but just read and wrote (escaped) the HTML where needed into the asp output.
