Microsoft MVP and Visual Studio LightSwitch Insider, Alessandro Del Sole recently released an extension that “provides an easy way to install a number of JavaScript code snippets for the LightSwitch HTML Client created by the LightSwitch Team at Microsoft”. I decided to use it to help you create the code to implement the JQuery Mobile Reflow Table in Visual Studio LightSwitch that was covered in the article: LightSwitch HTML Client For The Desktop Web Browser

To maximize performance, all applications must properly manage the flow of data. When dealing with an entity (one row of data), Visual Studio LightSwitch transfers the entire entity from the data layer to the client, the user interface (UI) layer.  When dealing with collections (rows of data) LightSwitch uses Visual Collections, and is very deliberate as to how, and when it places entities in the Visual Collection

An objection many developers have about using Visual Studio LightSwitch HTML Client for their projects, is that they feel they need normal web pages. To many developers, LightSwitch HTML pages look odd when viewed in a normal desktop web browser.

The Reflow table displays data in a desktop web browser like any normal data grid, yet it will dynamically pivot the table when the screen becomes smaller (rather than just squeezing the table smaller). A user can easily view and navigate the table on any sized device…

The primary reason you may want to use WCF RIA Services with Visual Studio LightSwitch 2012 is to:

  • Combine more than one entity into a single entity.
  • Eliminate unneeded columns in an entity to improve performance (otherwise large amounts of data, for example pictures, will be transmitted even when they are not shown).
  • Implement calculated fields that allow the resulting values to be searchable and sortable.

ComponentOne allowed me to play with their upcoming Wijmo controls for the Visual Studio LightSwitch HTML Client. The thing that makes them special is that they work as plug-ins in the LightSwitch HTML Client designer and allow you to create custom JavaScript with a click of a button.

LightSwitch in Action

By Dan Beall and Greg Lutz

You tell LightSwitch what you want the data to look like and what you want the interface to do and it wires it all up and gives you a finished, professional-grade application. LightSwitch is, at its essence, a forms-over-data application. You describe the data store and design the forms and it does all the plumbing required to make them work together. This article, based on chapter 1 of LightSwitch in Action, explains why and how you would want to use LightSwitch…
