Thank you for writing.
You can use the following code to scroll to the bottom:
private void radButton1_Click(object sender, EventArgs e){ radRichTextEditor1.RichTextBoxElement.VerticalScrollBar.Value = radRichTextEditor1.RichTextBoxElement.VerticalScrollBar.Maximum;}Please let me know if there is something else I can help you with.

This doesn't smoothly scroll the control to the bottom. It looks very unprofessional.
What else I can suggest is to manually change the value of the ScrollBar on every tick of DispatcherTimer. This way you could achieve a similar smooth scroll effect. For example, you could start the timer with a button click. Then you can use the radRichTextEditor1.RichTextBoxElement.ActiveEditorPresenter.ScrollToVerticalOffset() method to offset the thumb.
public int offset = 0;
private void Dt_Tick(object sender, EventArgs e)
{
offset += 50;
radRichTextEditor1.RichTextBoxElement.ActiveEditorPresenter.ScrollToVerticalOffset(offset);
radRichTextEditor1.RichTextBoxElement.UpdateEditorLayout();
if(radRichTextEditor1.RichTextBoxElement.VerticalScrollBar.Value >= radRichTextEditor1.RichTextBoxElement.VerticalScrollBar.Maximum - radRichTextEditor1.RichTextBoxElement.VerticalScrollBar.LargeChange)
{
dt.Stop();
}
}
DispatcherTimer dt = new DispatcherTimer();
private void radButton1_Click(object sender, EventArgs e)
{
offset = radRichTextEditor1.RichTextBoxElement.VerticalScrollBar.Value;
dt.Interval = new TimeSpan(0, 0, 0, 0, 100);
dt.Tick += Dt_Tick;
dt.Start();
}I hope this approach will work for you.
