HTML5 Viewer Enrichment

We're really excited about the ActiveReports 11 Service Pack 1 release. I think you'll like what we've done to improve the HTML5 viewer. In addition to adding user-requested tweaks and fixes, we've added several brand new features: SVG rendering, frozen row and column headers, and chart tooltips. Here are details on these features.

StackOverflow's 2017 Developer Survey: Loved and Dreaded Languages, Tabs and Spaces

At GrapeCity, we look forward every year to the results from StackOverflow's excellent developer survey. The research is invaluable to help us develop our roadmaps, understand where developers are headed, and what they're thinking about. Here are a few highlights from my first glance at the StackOverflow Developer Survey Results.

Runtime Interactions in WPF Gantt Chart

The new WPF Gantt control, GanttView, supports all the major Gantt chart needs--predecessors, dependencies, constraints, time-scales, etc. It also provides 17 built-in runtime dialogs so your users can seamlessly interact with the project management tool, and you won't need to write a single line of code.

Spread Windows Forms and the Waterfall Chart

A Waterfall chart is a popular visualization tool that you can now use in Spread for Windows Forms, a Visual Studio .NET control. Spread for Windows Forms also supports many other chart types. You can see a list of the many product features on our web site at http://spread.grapecity.com/spread-studio/.

Introducing MultiRow Data Grid for ASP.NET MVC

As often happens with our ASP.NET MVC Edition, we've recently introduced a new control that launched in Wijmo Enterprise several months ago. MultiRow Data Grid is a data grid that displays cells in a stacked format, reducing the need to scroll right to view additional columns. While it’s not a familiar spreadsheet format in North America, it’s very popular in Japan, and makes a lot of sense once you understand how it works.

Video: Get Started with InputPanel for WPF

InputPanel, a popular WinForms control that acts like a complete data-entry form, is now available in WPF and UWP. InputPanel manages the design, layout, appearance, and behavior of multiple input components. Here's a two-minute video that walks you through how to get started in WPF.

Enhance Transaction Logging with FlexGrid, a WinForms Data Grid

Enterprise applications need to keep track of history to effectively review or audit data. Most of these applications prefer to employ transaction logs for maintaining their history. In data-driven applications like spreadsheets, these transactions could be a direct result of any change in the data. Here, by maintaining a chronological ordered list of transactions in FlexGrid, ComponentOne Studio's WinForms data grid, you can record how and when state(s) of your application change.

FlexGrid Performance: Compare WinForms, WPF, UWP Performance

Since WPF's first release, people keep discussing whether its performance is comparable with WinForms, or whether this platform will eventually die. Now we're seeing the same questions about UWP. Let's try to answer with actual data about our FlexGrid performance.

Improve UWP performance with .NET Native 1.6

Good news to UWP developers: along with the new Visual Studio 2017, Microsoft has released .NET Native 1.6, which fixes a lot of the performance issues you may have experienced with Visual Studio 2015.

UWP FlexGrid Performance Review: Our Methodology and Results

We released our first UWP Beta in 2015. Since then, Microsoft has released several platform updates and we also made a lot of changes on our side to make our controls fast and stable. UWP FlexGrid performance has improved a lot from the first versions. Now I'd like to share the FlexGrid benchmark application that we use internally. It's similar to what we did for WPF but doesn't include any competitors.

WPF DataGrid Performance Review

Last summer we published the first version of WPF DataGrid Performance Comparison. Let's look at an updated version and share some new numbers. If you'd like to skip the methodology, jump right to the results.

Video: Happy Anniversary, Visual Studio! Here's GrapeCity's #MyVSStory

How to Navigate from a Chart in a FlexReport

One feature of FlexChartField is that you can navigate from the FlexChart to some other point within a FlexReport. When the report involves numbers (either shown in a table or a chart), you can use this feature to offer additional information about a specific data point in the series: the methodology, for instance, or summary values.

March 7: Join us for the Visual Studio 2017 Launch Party!

One week from today, Visual Studio 2017 launches... and we celebrate the IDE's 20th birthday! What's your fondest VS memory? Mine is getting a fancy, faster computer in 2010--after several years of waiting 20+ minutes for my ASP.NET 2.0 app to compile, it took mere minutes.

Some special features are commonly present in charts in reports. Data aggregation is a common concept when it comes to showing aggregated data in reporting. FlexReport's FlexChartField's data can be aggregated over the record source.
