c# - Autoscrolling in RichTextBox C# WinForms

Question

How can I do that if I append some text the RTB will automatically scroll down?

Now I'm using:

conversationRtb.Rtf = tab.conversationRtb.Rtf;
conversationRtb.SelectionStart = conversationRtb.Text.Length;
conversationRtb.ScrollToCaret();

But it isn't working well. Sometimes it doesn't scroll to end but one line before end.

Sometimes it makes a big offset.

I cannot find why. Is there any another way how to scroll down? I've found AutoScrollOffset but no examples how it works.

您可以调整HideSelection value to false，AppendText 将触发正确的滚动。
