This isn't exactly a trivial answer.

To do inline text formatting in a Rich TextBox like you want you will have to modify the Document property of the RichTextBox. Very simply, something like this will work

  
    
      
        Something
        Something Else
      
    
  
  

I think you could create a custom Control that creates a new block element and sets the font properties you need based on the user input.

For example, If the user types something then presses bold. You would want to wrap the previous text in a run and create a new run element setting the FontWeight to bold then the subsequent text will be wrapped in the bolded run.

Again, not a trivial solution but I can't think of any other way to accomplish what you are after.
