Count of text in RichtextBox (Line and Column)

Question

I'm working on a code editor and I just want to know how to do codes in counting Lines and Columns in richtextbox. Particularly something like this one in actual code editor:

enter image description here

Let's just say count will transfer in a ListBox.

Is there a fast way I can do it?

IF I understand correctly you want to code a feature (like your VS2010 screeshot) in C#. So `(1)` the question doesn't have anything to do with visual studio as such. => Which is why I've removed the tag. `(2)` Are you talking about windows form or WPF? — gideon, Apr 25 '13 at 10:55

You can do this :

//This to get lines number.
int index = richTextBox.SelectionStart;
int li = richTextBox.GetLineFromCharIndex(index);

// This to get columns number.
int firstChar = richTextBox.GetFirstCharIndexFromLine(li);
int col = index - firstChar;

Good luck!

This will do it, you just have to call the code inside a timer:

int line = 1 + richTextBox1.GetLineFromCharIndex(richTextBox1.GetFirstCharIndexOfCurrentLine());
int column = 1 + richTextBox1.SelectionStart - richTextBox1.GetFirstCharIndexOfCurrentLine();
label1.Text = "line: " + line.ToString() + ", column: " + column.ToString();
