Try this code:

private void UpdateCaretPos()

Point pt;

int line, col, index;

// get the current line

// get the caret position in pixel coordinates

// now get the character index at the start of the line, and

// subtract from the current index to get the column

// finally, update the display in the status bar, incrementing the line and

// column values so that the first line & first character position is

// shown as "1, 1"

label1.Text = (++line).ToString() + ", " + (++col).ToString() ;

Hi, Furqan

As long as I know, there is no such a method or command to directly find out the columns number and the rows number of the textbox. But, you can implement by yourself.

Your idea gonna be interesting, so I deal with it for you as an example, and it works well:

            int start = textBox1.SelectionStart;//record the position of the cursor in textbox

            int column = 0, row;

            for (row = 0; row < textBox1.Lines.Length; row++)

            {

                if (start < 0)

                    break;

                else

                    column = start;

                start -= textBox1.Lines[row].Length + 2;//each newline costs 2

            }

            column++;//columns begin with 1

You can put above code to the event SelectionChanged of RichTextBox, that is raised when the caret is changing.

Hope it helps
