A modular profile photo upload using ASP.NET MVC

ASP.NET MVC with Scaffolding and Razor template engine are great to get your LOB web application up and running shortly. But every once in a while, you find you need to do some extra work to add some features. Having a photo upload template was one of them.

My goals

  • To be able to edit user profile (name, email, etc.) as well as photo
  • To be able to view the uploaded photo before submit (similar to profile image upload of all social media apps)
  • To be built in compliance with ASP.NET MVC (i.e. no server-side controls)
  • To avoid writing extra code unless needed (no need for overkill)

Composite WPF and the Ribbon Control

While working for WPF and Composite Application Library (CAL) for the first time, I had some difficulty both understanding their concepts and apply them in the optimal way, but I tried harder.

One of the benefits of CAL I found was the Command Binding which truly facilitates complying to the Model-View-ViewModel UI Design Architecture. But finding an easy implementation for them in all the desired control was not as easy as with default menu items and tool bars. A question on stackoverflow was asking about implementing the Command Binding with the WPF Ribbon which is downloadable within the WPF Futures, and not included in the out-of-box visual studio installation.

The trick was to make custom region adapters as those of menu and tool bar. I have found samples of  RibbonRegionAdapter.

To comply with CAL and Model-View-ViewModel,  the View containing the Ribbon will be be bound to a ViewModel containing all commands. These commands would be exposed publicly and available to other modules to attach Executed and CanExecute handlers. It is possible also to expose a generic method to add commands at run time by providing their image and location on the ribbon.

I found also open source implementation for binding the docking manager. The Composite WPF Contrib Project on CodePlex contains a TabGroupPaneRegionAdapter for Infragistics TabGroupPane.
