richtextbox

问题 I'm implemented a RichTextBox in WindowsPhone 8. I fill this Box while runtime with Paragraphs, Runs, Images and HyperlinkButtons. The Problem that now appears is after some lines of content the RichTextBox is cut. I declared a red border that is also cut. Links and images are still displayed. Here is a Screenshot: My XamlCode is simple: <Grid x:Name="LayoutRoot" Background="Transparent"> <ScrollViewer> <RichTextBox x:Name="ContentBox" HorizontalAlignment="Stretch" VerticalAlignment="Top"

问题 I've come across some strange behavior of RichTextBox . I want it to be readonly , but then it doesn't display images when I use richTextBox.LoadFile(path) method to load .rtf file. When it's not readonly the file is loaded correctly and the images are displayed. I am using Windows Forms. Can I make it up somehow or is it another RTB bug? For now, as a workaround I am using a label to move focus to it while my RTB got focus, but I don't really like this one. 回答1: you can create a custom

问题 I am trying to implement very simple text formatting functionality for a RichTextBox in WPF. This just consists of a few bold, italic, etc ToggleButtons just above the RichTextBox. See image below, but ignore the top TextBox - the RichTextBox is the bigger one at the bottom. Toggling formatting for either a selection or at the caret position (for text that will be typed in) is not a problem, as I'm doing this: private void BoldButton_Checked(object sender, RoutedEventArgs e) { this

问题 I've a misunderstanding about FlowDocument, please help me to see clear. I'm working on a source code editor, where user can add few special variables, and later the program looking for this variables. For this editor, I'm using RichTextBox(RTB). I'd like to use color for these variables. It was not a problem to add color when the user add new variable to the text.

问题 I have a WinForms app with a multi-line textbox. This displays and retains (after loading from the DB) line break characters fine. However if I assign the TextBox.Text value to a string variable and then re-assign the variable back to the TextBox.Text property, the line break characters are lost and replaced with a square character (can't past them here as they just paste as a line break!) I've tried: Replace("\n",vbcrlf) but to no avail. Can anyone suggest a solution? UPDATE** I haven't

问题 I need to open a text file with ~4MB in a RichTextBox, but the end of the text was "trimmed". How do I override a RichTextBox.MaxLength Int32 limit? 回答1: I'm not sure how much text RichTextBox can handle, but I believe MaxLength only applies to text the user enters. If you set .Text directly it should be able to go past MaxLength, unless MaxLength is already at the maximum. 回答2: The default for RichTextBox.MaxLength is 2GB, so with a 4MB file this is not going to be your problem. 回答3: Besides

问题 I'm developing an advanced rich text editor in c# but have stumbled upon a problem that I can't seem to grasp. I have been trying to let users save their documents as Text files (plain text). By using the following: MyRichTextBox.SaveFile(filepath, PlainText); But the problem is that when they view that file (which should have been saved as plain text) in Notepad, it shows up with all of the RTF formatting codes whish makes their documents unreadable. Does anybody know of any other way to
