Greetings!
After upgrading to 2016 Q1, we've encountered a bug while appending text to radtextboxcontrol before setting anything to .Text property of it.
For example:
// Not working (exception is that 'startPosition' value cannot be null)
this.radTextBoxControl1.AppendText(String.Format("{0}", formattedString));
// Works
this.radTextBoxControl1.Text = " "; // maybe some initialisation goes here or smth...
this.radTextBoxControl1.AppendText(String.Format("{0}", formattedString));

Hello Ilya,
Thank you for writing.
It is a known issue in Q1 2016 version. You can track its progress, subscribe status changes and add your vote/comment to it on the following link - feedback item.
Currently, the possible solution that I can suggest is to append the text in the Form.Load event.
I hope this information helps. Should you have further questions I would be glad to help.
