Getting started with Metro Elements: Chart controls

Create an Appointment Tracking App with RadDatePicker & RadTimePicker
We all have a variety of uses for collecting Date and Time information from a user.

While the control exists for Windows 8 HTML Applications, it is very limited in its initial state. That is one of the reasons that Telerik has decided to make a more robust Date/Time Picker control and in this blog post we will explain how to use it in a simple app that keeps track of important appointments. So buckle up and let’s get started.

The Windows Store Submission Process


The Windows Store Submission Process
I recently got access to the Windows Store, and submitted my first app, “The game of Bao”, a simple and fun board game I learned when we visited Malawi, Africa during our honeymoon (any money the game makes will be donated back to an organization working on improving the lives of the kids that taught us this game, so please be kind and play it a lot and give some great reviews :-).
