Sparklines are small charts that you can use to provide visual representation of your data. Sparklines use data from a range of cells. SpreadJS supports sparklines in cells.
Many operations in FlexSheet—such as adding a new sheet, setting cell data, etc.—will refresh the FlexSheet. Multiple operations lead to multiple refreshes, which will eventually lead to a slower performance. FlexSheet's deferUpdate method ensures that FlexSheet will not refresh until all its included operations have been applied. As the FlexSheet will be refreshed only once, the performance of the FlexSheet will be improved.
This is the next in a series of blog posts that will cover the topics discussed in the ASP.NET Community Standup. The community standup is a short video-based discussion with some of the leaders of the ASP.NET development teams covering the accomplishments of the team on the new ASP.NET 5 framework over the previous week.
The FlexSheet control has a built-in calculation engine that supports over 80 of the functions supported by Excel. (See complete list.) Although the functions provided should cover the vast majority of use scenarios, in some cases users may need additional functions. FlexSheet provides two methods that allow developers to add their own custom functions: addCustomFunction and unknownFunction.
Wijmo includes several glyphs (images) defined as pure CSS, but if you're using Bootstrap, you might want to use their images instead. Adding a few CSS rules to your application will enable you to customize the glyphs used in Wijmo controls.
Our company has a long history of working with Microsoft. We've been writing UI Controls for Microsoft platforms since the early days of VB; in the 1990s, our famous FlexGrid control shipped in the box with Visual Studio. Most recently, we've been working with Microsoft to integrate Wijmo into Microsoft Dynamics. They'd planned to expand mobile support in their 2016 release, and one of the key features was new mobile UI controls. Microsoft chose Wijmo 5 for mobile input and gauges.
You can quickly access information on a web page with a hyperlink. SpreadJS supports hyperlink cells. This allows you to click on a cell and go to a web site, use an email link, or load a basic web page.
In our ongoing quest to serve you better, we've put together a survey entitled "How do you use open source?" We're planning to publish our results sometime this spring, and we'd love to hear from you.
When you want your MVC FlexChart available outside your application, for example in a report, Web API lets you export your chart as just about any image type you might want.

We wanted to post a quick note to call out that since yesterday, the .NET Framework 4.6.1 has been made a recommended update on WU (Windows Update). As we have already stated in the Exchange Supportability Matrix, at this time, this version of .NET framework is not supported by Exchange. In fact, we know of some issues if it is installed.
