I’d like to suggest you to use InitializeView to perform additional initialization to the view such as creating a view element at runtime or configuring the view background. Because what we are trying to achieve, to make its background transparent, is something that related to view-specific.

Utilizing InitializeView is suitable for most cases like following:

• To create a UIBarButtonItem and registers a view identifier to it;
• To add binding description manually in a view controller;
• To set the HideKeyboardOnReturn property to a textbox which instructs the iOS system keyboard to be dismissed when users tapped on the Return key;
• To show a toolbar programmatically at runtime;
• etc.

For more detail information, please refer to “Common View Context Members” documentation in http://developer.intersoftpt.com/x/rJ08#GettingStartedwithCrosslightiOSApp-CommonViewContextMembers.

The MainViewController.cs file in DataSamples sample project shows how to use InitializeView to do the following

• creates UILabel at runtime and customize its appearance;
• set TableView footer with the UILabel as described above; and
• set navigation title.

Hope this helps.
