Hi Srinivasa,
There are 2 things you can do:
(1) You can simply set the invisible property for the iViews (I think this is what you want).
You create a settings page which lists all the iViews, and when the user clicks a button, the page gets all the settings for all the iViews and sets the invisibility property for all of them.
The invisibility property indicates whether to display this object in the TLN/DTN.
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, IPcdContext.PCD_INITIAL_CONTEXT_FACTORY);
env.put(Constants.REQUESTED_ASPECT, PcmConstants.ASPECT_SEMANTICS);
env.put(Context.SECURITY_PRINCIPAL, request.getUser());
env.put(IPcdContext.PCD_PERSONALIZATION_PRINCIPAL, request.getUser());
iCtx = new InitialContext(env);
//Create loop of all objects 
    String pageID = "portal_content/DanielContent/DanRole/Folder1/Folder2/Page1";
    IPage myPage = (IPage)iCtx.lookup(pageID);
    myPage.putAttribute(IAttriView.ATTRIBUTE_NAVINVISIBLE,"true");
    myPage.save();
The above code is for a page, but you can do the same for an iView.
(2) If you iViews are in a page, and do not appear in the navigation tree, but you want to make them invisible, you can set this property on the iViews.
myIview.putAttribute(IAttriView.ATTRIBUTE_AVAILABILITY,IAttriViewValues.AVAILABILITY_VALUE_AVAILABLE);
myIview.save();
Either way, make sure to set the personalization environment variable when you do your PCD lookup, as shown above. Otherwise, the changes for one user will affect all users.
Hope this helps.
