Disable delete button on RichTextBox WF

Question

I am trying to disable people from deleting a textbox in a richtextbox. The project is using windows form.

Here is the code I have:

    private void         


        

Answer 1

My solution:

void richTextBox1_TextChanged(object sender, EventArgs e) {
  richTextBox1.SelectAll();
  richTextBox1.SelectionProtected = true;
  richTextBox1.Select(richTextBox1.Text.Length, 0);
}

Side note: yes, this will flicker. Proof of concept only. To avoid the flicker, see How to append text to RichTextBox without scrolling and losing selection?
