What’s New in v15.1

HTML5/JS Widgets

Deliver amazing mobile and desktop experiences.

HTML5 Pivot Grid (optimized for web apps)

The HTML5/JS Pivot Grid allows you to create a pivot table for multi-dimensional data analysis. The DevExpress HTML5 Pivot Grid supports data provided by OLAP services (MS SQL Server Analysis Services), and connects to any JSON data. By using the capabilities built into the Pivot Grid, large data sets can be summarized and represented in a cross-tabular format – and can be sorted and filtered as necessary. Because the Pivot Grid ships with numerous runtime customization options, end-users can also freely change its layout and data perspective based on their specific business requirements.

Appointments can be displayed using one of the predefined views - 'day', 'week', 'work week' or 'month'.
