How to get paragraph text from richtextbox when double clicking on it
I am having problems managing a WPF richtextbox control.
I want it to be as follows: I have a RichTextBox control called richTextBox1 that I have populated with data from a database.
I need to get the text on one line (which means - one paragraph) when I click on the control.
All I found on the net is the code to copy all the RTB text.
Any ideas how to get only the text on the line that was clicked?

I've done some major rework on the web and here's a working solution.
private void richTextBox1_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
TextPointer t = richTextBox1.GetPositionFromPoint(e.GetPosition(richTextBox1), true);
string textAfterCursor = t.GetTextInRun(LogicalDirection.Forward);
string textBeforeCursor = t.GetTextInRun(LogicalDirection.Backward);
string FullParagraphText = textBeforeCursor+textAfterCursor;
MessageBox.Show(FullParagraphText);
}

Correct code:
private void richTextBox1_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
TextPointer tp = richTextBox1.GetPositionFromPoint(e.GetPosition(richTextBox1), true);
TextPointer line_start = tp.GetLineStartPosition(0);
var nextStart = pos.GetLineStartPosition(1);
TextPointer lineEnd = (nextStart != null ? nextStart : pos.DocumentEnd).GetInsertionPosition(LogicalDirection.Backward);
TextRange tr = new TextRange(line_start, lineEnd);
string line = tr.Text;
MessageBox.Show(line);
}

OOPS, I made the lines in reverse order. Here's the reworked code ... :) Ohad.
private void richTextBox1_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
TextPointer t = richTextBox1.GetPositionFromPoint(e.GetPosition(richTextBox1), true);
string textAfterCursor = t.GetTextInRun(LogicalDirection.Forward);
string textBeforeCursor = t.GetTextInRun(LogicalDirection.Backward);
string FullParagraphText = textBeforeCursor+textAfterCursor;
MessageBox.Show(FullParagraphText);
}
