WinForms Data Grid: breaking change with Conditional Formatting (v14.2)

AddThis Social Bookmark Button
A week or so ago, Don published a blog post about our new Microsoft Excel-inspired conditional formatting feature for the WinForms data grid, XtraGrid, that’s coming in v14.2. (Again, the release is only a few weeks away, the beta is out if you are an active DXperience or Universal customer, get it now and try it out, etc.) It turns out that there is a subtle breaking change with this new feature. However, it’s very easily worked
around. First, a bit of history. With v14.1 or earlier, we had what we called “Format Style Conditions”, a feature that allows you to apply different formats to the data in your grid according to some pre-defined criteria. We did not provide any ability for run-time customization, you got what you programmed. Fast-forward to now and for v14.2 we’ve ported some work we’d been doing on the WPF Grid to the WinForms Grid. For this release we have improved the speed of the condition-matching code and also have provided full run-time customization for end-users. Crucially we have also provided...(Read whole news on source site)

Entity Framework Pitfalls – Registering Custom Database Functions for LINQ

AddThis Social Bookmark Button
Like I said in my previous post, it’s not enough to add a DbFunctionAttribute attribute to a method to have it call a database function. If the function is not a built-in one, it will not be registered in the Entity Framework provider manifest for SQL Server, so it will require registration in the model. You might think, just by looking at the methods in SqlFunctions that all that it took was to add this attribute, but you would be wrong.

Random Link Roundup–11/20/2014

What time is it?  It’s time for Friday’s link roundup!  So the biggest news (and the reason for this week’s image!) is that Rob Eisenberg has left the Angular 2.0 team.  Rob is a heck of a developer, creating such awesome frameworks as Caliburn and Durandal.  Losing him is a Big Deal.  It’s not Doom and Gloom time yet, but I kinda feel like that’s where we’re headed… Rob Reynolds of Chocolatey had a successful Kickstarter this week.  He also wrote about how the passion of a few
people and their tools saved Windows. Underlined links in web browsers are ugly.  Or at least, they were.  Smarter Link Underlines gives you some simple(ish) CSS that will beautify your links. Material-UI is a library and CSS framework for building “Material Design” compatible apps.  The CSS could be used anywhere, but the components themselves are for ReactCSS Dig is an interesting tool that could help you spot both duplication and inconsistencies across your CSS. The stock Android emulator is notoriously slow.  The Visual Studio Emulator for Android, however,...(Read whole news on source site)

Mobile Essentials: Productivity Tools for Mobile Developers

AddThis Social Bookmark Button
A bunch of mobile development and tooling enthusiasts here at the office wanted to put out some tools, templates and general productivity enhancements for mobile developers, so we decided to set up a custom Visual Studio gallery that you can set up to get these tools in an integrated fashion in the Extensions and Updates dialog (a.k.a. Extension Manager). These will generally be projects we work on the side, on weekends and nights and hackathons. The goal of these extensions is to be completely independent of your other tools in VS (like your Xamarin installation) so that you can try them
without risking breaking your stable development environment. If something doesn’t quite work, you just remove the extension and you’re done. Pristine environment back! At Xamarin, we may use this gallery also for early prototypes or spikes we do on top of the Xamarin Platform, so that we can gather early feedback without disrupting your stable installation and without requiring you to switch between official channels. Whatever we put out will be for use “at your own risk” so to speak. As I said, it could become a way for us to also share bits earlier and get timely feedback for...(Read whole news on source site)

WinForms and WPF Spreadsheet: Grouping and AutoFilter (Coming soon in v14.2)

AddThis Social Bookmark Button
The premier spreadsheet control for Windows developers is getting a couple of much-requested features for v14.2: data grouping, and filtering of data using the AutoFilter feature. Let’s see what these involve. Data Grouping One of the biggest new features of our WinForms, WPF, and ASP.NET datagrids in v14.2 is the ability to export data from the grid to an XLS/XLSX file and maintain the grouping and sorting currently configured in the grid. The requirement is to allow end-users to group, sort, filter data within the grid, export the result to an XLSX file, and then open up that
file in Excel to continue analyzing that data. All grouping, sort orders and filtering options transfer to the XLSX file and the user is given a similar look to the data within Excel. See here for details on this new functionality. Well, anything Excel can do our spreadsheet controls should be able to do too, and with v14.2 we’ve added data grouping to the control. You can group data by using the corresponding commands of the Outline group on the Data tab on the corresponding ribbon. ...(Read whole news on source site)

RavenDB 3.0 Release date: 25 Nov, 2014

AddThis Social Bookmark Button
Barring anything major, we’ll be releasing RavenDB 3.0 in 5 days . It will be  a stable release and you’re encourage to move to it as soon as it is available, using the Esent database. The Voron database is still in RC mode (mostly because we’re paranoid and want to have more real world experience before we go full forward with this), but it is going to be fully supported. Upgrading instances will use Esent, and new databases will default to Esent unless you explicitly select Voron.
