RadRangeSelector (New control)

  • When working with large amounts of data, it is easy for a user to get overwhelmed and lost in a sea of information. RadRangeSelector provides an elegant solution to this problem. RadRangeSelector allows users to focus specifically on a subset of data when they interactively and visually select a range in the chart. This range is then visualized separately on its own allowing users to see and focus on that specific data, free and uncluttered from the rest of the information displayed in the main chart.

RadRating (New control)

  • The ability to rate a product or service is a common feature that you see everywhere, from ecommerce websites to doctor’s offices. With RadRating, we bring this functionality to your Windows Forms application. This control has the ability to display ratings via any number of Visual Elements like Stars, Hearts or Diamonds. Multiple selection modes are available allowing you to accept only full ratings, half ratings or even precision ratings, where you give the users the ability to set a decimal value like 2.4 stars
