Wijmo 5 is a JavaScript UI controls library specializing in data grids and charts, known for its high performance and zero dependencies. It features a core set of extensible controls, including the FlexGrid, and is built entirely in TypeScript, allowing developers to leverage C#-like syntax. The framework integrates well with AngularJS and Bootstrap, providing tools and resources for modern web application development.

3. What is Wijmo 5?
 JavaScript UI Controls
 Zero dependencies
 Specialize in data grids and charts
 Includes the famous FlexGrid control
 Focus on performance
 Small core controls and extensible
 Offer additional features as optional extensions

4. Wijmo Stats
 Distributed Team
 US, Brazil, Canada, Russia, China, India, Myanmar, Japan
 Over 100,000 lines of code (just in Wijmo 5, millions company-wide)
 Over 25 years of experience (first control written in VB)
 Our FlexGrid control can data-bind 1,000,000 records in under 1 second

5. What Makes Wijmo 5 Special?
 True Controls (Control Classes like in .NET)
 Not Widgets
Control
//Initialize
var myFlexGrid = new wijmo.grid.FlexGrid('#myFlexGrid');
//Show Row Headers
myFlexGrid.headersVisibility = wijmo.grid.HeadersVisibility.All;
Widget
//Initialize
$('#mywijgrid').wijgrid();
//Show Row Headers
$('#mywijgrid').wijgrid('option', 'showRowHeader', true);

8. Our Tools
 Visual Studio
 TypeScript
 AngularJS
 Bootstrap
 Browser Dev Tools
 BrowserStack

9. Visual Studio Project Setup
 Visual Studio Project for Control Library
 Folders for Namespaces
 TypeScript files for Classes
 Builds like a standard VS PRoject

10. Sample Setup
 Each Sample has a VS Solution and Project
 Solution contains
 Sample Project
 Wijmo 5 Project
 Wijmo 5 source is compiled when sample is
run
 Wijmo 5 source can be debugged when
running samples

11. Debugging Source Code in Visual Studio

12. Builds
 TFS used for Source Control
 Nightly Builds
 Use MSBuild tasks
 Compile TypeScript
 Add headers/license/copyright to files
 Run Unit Tests
 Build passes/fails based on Unit Tests

13. TypeScript
 Language from Microsoft
 Created by Anders Hejlsberg, the creator of C#
 Object-oriented with Classes etc.
 Compiles to JavaScript (ES5 or ES6)
 Offers C#-like syntax and features
 Inheritance
 Type safety, design-time error checking
 Based on ECMAScript standards (ES 6)
 Adopted by Google in Angular 2

14. Wijmo Uses TypeScript
 Our Source Code is all written in TypeScript
 Our developers can apply their C# experience and skill to JS
 We can structure our control library like we would in C#
 Base Control Class
 UI Controls that inherit Base Control Class
 We get C# features when developing
 IntelliSense (autocomplete) in Visual Studio
 Error warnings while programming (no need to wait until runtime to see errors)
 Our controls are extensible
 We can extend our controls easily to add features as extension Classes (like FlexGridFilter)

15. TypeScript Demo

16. AngularJS
 MVVM Framework
 Similar to .NET/XAML in JavaScript
 Two-way binding
 Components

17. Wijmo Supports AngularJS
 We create AngularJS directives for each of our JavaScript Controls
 Our directives support two-way bindings for properties that benefit from it
 We offer templates to make declaring controls even richer (like Cell Templates in
FlexGrid)
 Many of our samples are created with AngularJS
 It is really nice to declare Controls using markup

18. AngularJS Demo

19. Bootstrap
 Mobile-first UI framework
 Building blocks for UI
 Forms (Input, Buttons, etc.)
 Navigation
 Layout (Responsive)
 Icons
 Easy way to jump-start UI for an application

20. Wijmo Likes Bootstrap
 Our default theme matches Bootstrap
 We use Bootstrap in our Samples
 Layout
 Navigation
 Simple UI (buttons, tabs, etc.)
 Using Bootstrap for simple stuff allows us to focus
on the complicated UI controls like Grids/Charts

21. Browser Dev Tools
 Spend a lot of our time in Dev Tools
 Inspecting Elements
 Stepping through code
 Profiling for performance
 Memory profiling (for leaks)
 FPS monitoring (preventing jank)
 Emulating devices

22. Browser Stack
 Web-based Cross-device testing
 Test any browser, on any device, running any
OS
 Ideal to quickly confirm issues/fixes in
environments you don’t have setup
 Can also easily connect to localhost (with perf
cost)
 Covers most needs for testing
 Not ideal for debugging
 Not ideal for testing performance issues since
it is an emulation across web
