I want to highlight some stuff on a web page and be able to paste it into a richtextbox in C# winforms. I want to then be able to see the HTML code of what I had pasted. Is this possible?
This snippet will return a string containing the code. There is some header info at the top that you may want to parse out but it is pretty straight forward.
string html = Clipboard.GetData(DataFormats.Html).ToString();
You will be able to populate that into a text box or richtext box however you like.

I am trying to format a hyperlink in a Rich Text Box using the Rich Text Format. I can get basic formatting working thanks to this answer, for example making text bold. However I cannot get the RTF formatted hyperlink to work. I found an example of making an RTF link here. However, when I try to put this in the Rich Text Box as seen below, it causes my application to crash. Any suggestions as to what i'm missing here?
string my_hyperlink_text = #"{\field{\*\fldinst HYPERLINK \"http://www.google.com/\"}{\fldrslt Google}}"
if (rtbControl is RichTextBox & rtbControl.Name == "name_of_control") // Making sure the control is a RichTextBox
{
RichTextBox rtb = rtbControl as RichTextBox;
rtb.Rtf = my_hyperlink_text;
}
An easy way for getting rtfs to work is to write your text in Microsoft word, copy & paste it to Wordpad and the saving it as a RTF from there.
The detour with MS Word is needed, because WordPad does not support entering links in the UI, although it handles them correctly when they come from other sources, like the clipboard. Also, MS Word creates massively bloated rtf.
The rtf file you create this way can then be opened in any text editor and can be used as a string constant in your program.
In your case, I suppose that the prefix and maybe the color table are missing and are causing the problem.
By the way: Wordpad is not much more than a wrapper around the Windows rtf control, i.e. the same control that you are using in your code.

RTF encoding is different from HTML.
If not, then you need to write your own HTML to RTF converter or find something similar.

I have a TextArea control in my ASP.NET page which gets populated with a paragraph containing multiple sentences from the database. After this data gets populated in the TextArea control, I need to search for a few words in them and highlight them in different color. The words that I need to highlight are present inside a table in the database.
My question is : How do I highlight the selected words in a TextArea control using C#?
Please help. Thank you.
The HTML <textarea> tag doesn't contain the ability to add any text formatting. If you want to highlight a portion of your text, then you'll need to display it within a <div>, <span> or some other HTML element.
If you need to make the text editable and still highlight portions of it, then you could use a WYSIWYG HTML editor, such as the jHtmlArea Free, Open Source jQuery plugin.
Shameless Plug: jHtmlArea is a jQuery plugin I created a while back to fit a need I had for a light weight, easily extensible WYSIWYG HTML editor.
You can look into the DynaCloud jQuery plugin, or CodeMirror. Both provide some functionality for highlighting text.

I need help with it and i'm sure its simple but I cant figure it out.
In my rich text box I copy a link in and I dont want it to be a hyperlink.
So how do I remove the hyperlink?
It seems you're asking about hyperlinks in the RichTextBox in Windows Forms. If so, it's simply a matter of setting the DetectUrls property to false:
richTextBox1.DetectUrls = false;
string BadInput=Textbox.Text....
string GoodInput=BadInput.Replace("<","<").Replace(">",">");
Of course, this is assuming you don't want any HTML to be allowed in the text box.
