Visual C++ :: Insert Common Control Into View Dynamically

This is what I try to achieve:

1. Using a CScrollView as the View class type.
2. Using Document/View Architecture.
3. Insert multiple Common Controls such as CEdit, CButton, CListCtrl into the View dynamically.
4. All the Common Controls is base on a template created by user. So I do not know the quantity of the Common Controls.

This is the plan on how to do it:

1. In View OnInitialUpdate(), read the template to get all necessary info on the Common Controls to be create.
2. In View OnInitialUpdate(), create all Common Control. Some Common Control may not have WS_VISIBLE as it may not needed at initial stage.
3. In View OnUpdate(), I need to refresh the Common Control properties such as is its text, position or its visibility. This should happen if Document call UpdateAllView().

My Question:
1. Is this a normal & useable plan?
2. Do I miss other functions for any other messages?
3. Still wondering if I need to involve any coding in OnDraw() for this plan.
