richtextbox

问题 I need to use a RichTextBox, not a normal textbox because of the way it keeps the caret position, from line to line. But I need to keep the text in the same font all the time even if it is pasted. At the moment I have it selecting the entire text and changing the font to the original (Lucida Console) but it look horrible when you paste into it as it flashes blue. 回答1: If you are handling the pasting programatically don't use the Paste method.

问题 How I can bottom align text in RichTextBox? It seems that control doesn't support it directly. So I am looking for ways to emulate it.

问题 I am looking for a very minimal jQuery rich textbox plugin for a web app I am working on. The user will only need to see the 'textbox', and not any toolbars as all of the rich formatting will be coded depending on what they type. I have attempted to create my own with an iframe, but there are problems. One of them being when wrapping strings in divs, the caret is moved to the beginning and it can't be moved inside the div without clicking. http://jsfiddle.net/DVjYa/ This is a problem because

问题 I need to programmatically add a new paragraph to a RichTextBox control (just like pressing Enter). Using the code below, it does add a new paragraph but: It deletes all the existing text in the control The insertion point remains in the first line and doesn't move to the second newly created line It only seems to add a new paragraph once, i.e. if I run the code a second time, a third paragraph isn't created FlowDocument flowDoc= rtbTextContainer.Document; Paragraph pr = new Paragraph();

问题 I am using a RichTextBox in my code where I show syntax-highlighted code. Now, on every keystroke, I have to re-parse all the tokens and re-color them all over again. But the only way to color individual words in a WinForm richtextbox is to select those words one by one and color them using SelectionFont.
