richtextbox

I need help on creating a new line for my RichTextBox which I cant make work when using CheckBox. It keeps overlapping instead of creating a newline of words. Tried using the method of rtbdisplay.text = (display+envrionment.newline); example from my code: if (rbtnSmall.Checked == true) { rtbDisplay.Text = "displaytext".PadRight(20) + "size".PadRight(23) + qty.ToString().PadRight(20) + StrongDummy; } Use the RichTextBox.Text property or the RichtTextBox.AppendText method to append a string with a newline. myRichTextBox.Text += Environment.NewLine + "My new line."; // Or myRichTextBox.AppendText

I'm using a RichTextBox (.NET WinForms 3.5) and would like to override some of the standard ShortCut keys.... For example, I don't want Ctrl+I to make the text italic via the RichText method, but to instead run my own method for processing the text. Any ideas? Ctrl + I isn't one of the default shortcuts affected by the ShortcutsEnabled property. The following code intercepts the Ctrl + I in the KeyDown event so you can do anything you want inside the if block, just make sure to suppress the key press like I've shown. private void YourRichTextBox_KeyDown(object sender, KeyEventArgs e) { if (

At the moment I'm working on a simple syntax highlighter and I have couple of problems. Could you help me out? I have a class library with a component class in it. Everything is in VB.NET. It's only one file so you can see it here https://gist.github.com/2366507 . On line 92, there is the OnTextChanged Sub. I was thinking about adding ProcessAllLines() (as on line 128) to the end of that Sub, and it worked. However when I was typing in code to the RichTextBox (source which I used is here https://gist.github.com/2366526 ) after each text change it was checking and processing ALL the lines. So I

If txtLog is a RichTextBox control: Dim text = "hi" & vbCrLf Debug.WriteLine("t:" & text.Length) ' --> 4, as expected txtLog.Text = text Debug.WriteLine("tL:" & txtLog.TextLength) ' --> 3. muh?! :( Having looked at the RTF spec , the end of a paragraph is notated as \par , which is neither CR nor LF . This makes sense since RTF is markup language; like in HTML, line endings have little meaning on their own. So presumably, on writing into the RichTextBox , my line ending is being encoded into \par . And then, on extraction, the \par is being translated back to a real line ending for use. It

This code: <StackPanel Orientation="Horizontal"> <RichTextBox /> <Button Content="Dialog" /> </StackPanel> shows the button somewhere on the left side of the StackPanel ONTO the RichTextBox, WHY? edit: Oh I just saw its a width problem. The RTB has nearly no width and the button is righthand of it. edit: seems I run into this bug: WPF RichTextBox with no width set solution does not work for me! You'd be better off using a Grid and the HorizontalAlignment (and VerticalAlignment) properties of the RTB. <Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Grid.ColumnDefinitions>
