Multiline Textbox with automatic vertical scroll

August 5, 2023 by Tarik

According to this question: TextBox.ScrollToEnd doesn’t work when the TextBox is in a non-active tab

You have to focus the text box, update the caret position and then scroll to end:

Status.Focus();
Status.CaretIndex = Status.Text.Length;
Status.ScrollToEnd();

EDIT

Example TextBox:

<TextBox TextWrapping="Wrap" VerticalScrollBarVisibility="Auto" 
         AcceptsReturn="True" Name="textBox"/>
