opening file into right-hand view of MFC SDI app

I have an mfc sdi APP.
A load of files are shown in the tree-view on the left. This tree-view is populated from the document, which lists files and folders with their hierarchy.

Now, I want to right-click on a file and select a pop-up menu option to open the file into the right-hand pane. I can do the right-click and pop-up menu bit. However, the document that populates the tree-view is not the same document that opens into the right-hand pane.

I have done this by just passing the path of the file selected from the tree view straight into the CRightHandView class and reading the file and calling SetWindowText. It works but I am not sure I am using MFC framework in the way it is intended. Is there a more correct or elegant way?

It's a while since I used MFC but as I recall the model, you should connect the CView to a CDocument (ClassWizard does it for you). Then when the user requests a file to be opened, the CDocument class should handle it and read it into memory and then call the associated CView class to display the data in whatever way is necessary. This also allows for the document to be updated and then signal any connected views to update their displays. There are probably still some MFC tutorials around with examples of this.

If you are using SDI, by definition there can only be one open document at the time.
Sounds like your design concept is correct. Tree view represents the document, the right side view can be anything - effectively files are opened as necessary, as items get selected in the tree view.
If you need to do some editing in the right view (not sure if you have to), then you will have to use your own customized handlers for these operations as your in-built serialization mechanism will only help with changes in the tree view.
All good I think.
