Set current caretPosition in RichTextBox viewport end?

Question

I already used the below code. It moves current caret position in viewport top.

FrameworkContentElement fce = (tpNextLine2.Parent as FrameworkContentElement);
if (fce != null)
{
    fce.BringIntoView();
}

I want to move current caretposition textpointer in richtextbox viewport end using WPF.

How can I achieve this?

Answer 1

If you don't want to change current caret position but scroll the WPF RichTextBox to move this position to the bottom of the visible area, you can use this code:

Rect rc = rtb.CaretPosition.GetCharacterRect(LogicalDirection.Forward);
rtb.ScrollToVerticalOffset(rc.Bottom + rtb.VerticalOffset - rtb.ViewportHeight);

Answer 2

Try this code :

RichTextBox1.Select(RichTextBox1.Text.Length - 1, 0);

RichTextBox1.ScrollToCaret();
