richtextbox

I have searched around on the net but I cannot find a method of copying/cutting/pasting selected text from a RichTextBox . Even MSDN does not have an answer. The code they provide does not work: Copy() only appears to work on TextBoxes, not RichTextBoxes. If you're using .NET 3.0 and above you can always use Clipboard.SetText() I found it useful to use the Clipboard when I want everything in the richTextBox without having to select everything first or when I need to change the string: string text = "Summary:" + Environment.NewLine + this.richTextBoxSummary.Text; Clipboard.SetText(text); if I

This question already has an answer here: Check if selected text on richtextbox is all bold or not 1 answer How to check if selected text on richtextbox that its chars is not all bold. For example: notbold bold notbold ← this is mixed.

While creating a customized editor with RichTextBox, I've face the problem of finding deleted/inserted text with the provided information with TextChanged event. The instance of TextChangedEventArgs has some useful data, but I guess it does not cover all the needs. Suppose a scenario which multiple paragraphs are inserted, and at the same time, the selected text (which itself spanned multiple paragraphs) has been deleted. With the instance of TextChangedEventArgs, you have a collection of text changes, and each change only provides you with the number of removed or added symbols and the

When I use the RichTextBox.Select(int start, int length) function to select text in a rich text box that contains hyperlinks, there is some shift in the selection when I try to select any text that is after the hyperlink. When I remove the hyperlink, the selection works properly. Edit: I use RichTextBox 5 (the default in Visual Studio is version 4) public class RichText50W : RichTextBox { [DllImport("kernel32.dll", CharSet = CharSet.Auto)] static extern IntPtr LoadLibrary(string lpFileName); protected override CreateParams CreateParams { get { CreateParams prams = base.CreateParams; if

In WPF I would like to create custom Inline implementation. From documentation of Inline : "An abstract class that provides a base for all inline flow content elements." Classes like Figure , Run or Span inherit from Inline . My custom class inheriting from Inline would be something like '2 lined Run'. I have special needs for flow of document and this seems to be the only way. However I don't know where to start: Inline does not define any members! It is abstract class so it is meant to be inherited but there is no documentation on how to inherit from it. Not in MSDN and nowhere else where I
