Try this code

public bool isRichTextBoxEmpty()
{
    TextPointer startPointer = MyRTB1.ContentStart.GetNextInsertionPosition(LogicalDirection.Forward);
    TextPointer endPointer = MyRTB1.ContentEnd.GetNextInsertionPosition(LogicalDirection.Backward);
    if (startPointer.CompareTo(endPointer) == 0)
        return true;
    else
        return false;
}

I picked this up from here[^].
