There any other way to accomplis...

All that I need is to have a control that will enable me changing the background/foreground of a part of the text... I'd need that in winforms... anybody know anything about some kind of ...
When I am viewing a document in Wordpad (or Word) the text is word wrapped around the document boundaries. Altough when I using the RTF string in a RichTextBox the text is wrapped around the control border. This means when I change the size of the window the wordwrapping changes. Is there something I can do about this ? (some kind of mo...
I use the WPF RichTexBox control in WPF project. The problem I get stuck in is it cannot display the unicode as the System.Windows.Forms.RichTextbox in Win Project. E.g : When I copy a paragraph of Chinese language and paste it to the WPF Richtextbox. The font is break and it cannot display. But when I use System.Windows.Forms.RichTextb...
I am using the System.Windows.Forms.RichTextBox control in .NET 2.0 and am using c#. I have an array of strings that I would like to append to the RichTextBox, but I do not want to create new paragraphs in the RTF.

I have a RichTextBox which contains links posted by the users. The problem is that my RTB makes the color of the links black, and the background color is also black. This leads to the links being invisible. How do I change the color of the links in the RTB? ...
Language = C# .NET version = 3.5 When my code performs syntax highlighting the text appears, to the user, to be scrolling automatically.

Hello, Does anyone know of a GWT widget that works like a spelling suggestor? Ideally it would be similar to this: http://www.polishmywriting.com/ I need a click-triggered popup on user generated text so that I can suggest replacements (I am not building a spell-checker, but something similar). I also really like the way the polishmy...

I may be completely imagining this, but I could have sworn there was a way to make individual Run (or Parapgraph) elements in a RichTextBox read-only. I also could have sworn I tried a method for doing this out myself a few weeks ago and was satisfied with the results - I vaguely remember it looked something like this: <RichTextBox x:Na...
Where can I find a control for WinForms that will highlight source code pasted into it? I would like one that has syntax highlighting support for many different languages but if it only works with C# I would be fine with that also. ...
Is there any JS function that can change the color of certain text in a textarea? For example, blar blar {blar} blar, {blar}, including { }, will be in blue. Other words will be in blank.

Ok, I'm trying to add a "custom property" to a piece of text in a RichTextBox control. I thought it would be easy, but apparently not :-) The basic functionality I want is to be able to set a property on a particular word and be able to detect, when a word is double clicked, if that property is there or not. My intial approach was to c...
Hello, I'm having a problem with storing amazing amounts of text in a rich TextBox. I'm trying to read a text file fairly big( anywhere from 90mb to 450mb), and put what I've read in a rich textbox. It works in a simple program, but when I do in a complicated program I get an OutOfMemory exception. One thing to note is that when I e...
I have a question related to managing OLE objects in a RichTextBox. What I've found so far is lots of info, but not exactly what I need, so I will make a quick introduction first (I also hope someone might find this helpful). 1.
