richtextbox

Say I clicked somewhere inside a RichTextBox control. How can I get the current line the caret is currently on? Btw this is to retrieve the whole text string of that line. That's what RichTextBox.GetLineFromCharIndex() does. Pass the SelectionStart property value. This worked for me: this.WordWrap = false; int cursorPosition = this.SelectionStart; int lineIndex = this.GetLineFromCharIndex(cursorPosition); string lineText = this.Lines[lineIndex]; this.WordWrap = true; One way is to send it the EM_LINEFROMCHAR Message . I'm sure there are other ways. user718424 If you want to get current Line

I'm using in my winform project a RichTextBox control to display a kind of old console screen. This works perfectly but there is a space between the lines. Is it possible to change this space to be 0 or anything near that. If i paint a line from vetical line from line 1 to line 5 i don't want any spacing between the line. Hope you can help me. There's actually a lot that the Windows Forms RichTextBox doesn't expose. If you have the HWND (Handle property) to the control, you can use the SendMessage API to send the EM_SETPARAFORMAT message to play with the formatting. In particular the

The task: Make the text content of the InlineUIContainer to be inline with the outer text. The standard behaviour of the InlineUIContainer content is when the bottom edge is inline with the outer text. It is possible to shift the position of InlineUIContainer with RenderTransform, but the value of Y has to be chosen for each font type and size - not a perfect way. <RichTextBox> <Paragraph> LLL <InlineUIContainer> <Border Background="LightGoldenrodYellow"> <TextBlock Text="LLL"/> </Border> </InlineUIContainer> LLL </Paragraph> <Paragraph> LLL <InlineUIContainer> <Border Background=

For my C# RichTextBox, I want to programmatically do the same thing as clicking the up arrow at the top of a vertical scroll bar, which moves the RichTextBox display up by one line. What is the code for this? Thanks! Here's what I do: using System.Runtime.InteropServices; [DllImport("user32.dll")] static extern int SendMessage(IntPtr hWnd, uint wMsg, UIntPtr wParam, IntPtr lParam); then call: SendMessage(myRichTextBox.Handle, (uint)0x00B6, (UIntPtr)0, (IntPtr)(-1)); Seems to work OK - you might need to tweak things a bit, though. Hope that helps. For future reference the EM_LINESCROLL message

In my project I want to count lines displayed by richtextbox in C# with word wrap property set true. For example, in richtextbox, I write a text, and when text reaches the width of the richtextbox, then it automatically goes to second line. So what happens is the text contains actually one line but it is displayed in two lines. So I want to know how can I count this as two lines instead of one? Help will be really appreciated. You may go for RichTextBox.GetLineFromCharIndex Method Retrieves the line number from the specified character position within the text of the RichTextBox control. If

A XAML text stored in database, how can I show its text in a RichTextBox after reading the XAML by XmlReader? StringReader stringReader = new StringReader(xamlString); XmlReader xmlReader = XmlReader.Create(stringReader); rt.Document = ??? ------UPDATE------------------- here is the xamlString contents: <Section xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml:space="preserve" TextAlignment="Left" LineHeight="Auto" IsHyphenationEnabled="False" xml:lang="en-us" FlowDirection="RightToLeft" NumberSubstitution.CultureSource="User" NumberSubstitution.Substitution="AsCulture"

I am trying to fit a WPF RichTextBox to exactly accommodate a grid of characters in a particular monospace font. I am currently using FormattedText to determine the width and height of my RichTextBox, but the measurements it is providing me with are too small--specifically two characters in width too small. Is there a better way to perform this task? This does not seem to be an appropriate way to determine the size of my control. RichTextBox rtb; rtb = new RichTextBox(); FontFamily fontFamily = new FontFamily("Consolas"); double fontSize = 16; char standardizationCharacter = 'X'; String

I placed a RichTextBox control on a new form and launched the project. So the RichTextBox.Text = ""; Each time I press Up or Down keys I heard the annoying BEEP sound! How to get rid of this issue? Using "e.SuppressKeyPress = true" in the KeyDown method locks the Cursor position. Well, you can try suppressing the key only if the caret is on the first line and the key is up, or on the last line and the key is down or in position 0 and the key is left, etc. That said, this is how most textboxes behave, and the sound is set in your operating system preferences. You'd get the same beep in, say,
