Evaluated (Calculated) Column for WPF/Silverlight RadGridView with IronPython
The Dynamic Language Runtime (more info here) is a great way to spice up those boring old CLR applications. Not only has the DLR helped bring the dynamic keyword to C# 4, but it helps Python and Ruby live on top of .NET. Using the DLR and IronPython, it's relatively easy to craft a calculated column, giving you the power to execute IronPython expressions over your data objects. What's more, you can import Python modules such as math, datetime, etc. You can download the source code for this example here. The exact same code can be used for both Silverlight and WPF....July 12, 2010 -

Export Beyond Excel with RadGridView for WinForms
The RadControls for WinForms Q2 2010 beta release has been live for a couple of weeks now, and we have been getting excellent feedback on the fancy new features. Along with several brand new components (RadListControl, RadPageView and RadDesktopAlert to name a few), we have introduced a completely redesigned grid, along with numerous new features and possibilities. Up until now we have supported Export to Excel capabilities in RadGridView, and not much more. Although ExportToExcelML offers some cool and unique features, exporting only to Excel was not enough for our clients. Our integration with Telerik Reporting could not suit all of our client's requirements either. Now,...July 07, 2010 -

How to: Validate data with SL/WPF RadGridView Part II – asynchronous validation on item/row level via RIA services and INotifyDataErrorInfo interface
In my previous post I’ve tried to explain RadGridView validation mechanism and support for 2 layers of validation (UI and Data) for a property/cell level. RadGridView exposes same events on a row level too (RowValidating, RowValidated and RowEditEnded). Since this theory you can find on our online help I’ll begin with the interesting stuff - asynchronous validation example. I’m glad to announce that with the next (2010.Q2) version RadGridView will support asynchronous validation. By asynchronous validation I mean that RadGridView can save a value in its collection and from somewhere (server side usually) to receive a message that this value doesn’t pass some...July 02, 2010 -

How - to: Change the Default Keyboard Behavior in RadGridView for Silverlight/ WPF
RadGridView provides a set of keyboard navigation scenarios that will result in certain consequence of commands to be executed. Thus – and naturally in this case - when clicking on the Del–button will cause deletion of the current item, Ins-button will add a new one into the grid. However, there exists a great possibility that you do not need this pre-coded behavior and you want to predefine it. In that case you can follow up one of the following two scenarios. The first one is to use the basic interface responsible for the keyboard navigation – IKeyboardCommandProvider and implement your own...June 30, 2010 -

RadReminder for WinForms brings Outlook interfaces to your application
The Q2 2010 release introduces a brand new RadReminder component. Its purpose is to enable users to track different objects and their events. The architecture is pretty simple and intuitive and allows any IRemindObject implementation to be monitored by a RadReminder instance. The component comes with a built-in dialog that displays all the currently tracked objects in a grid and enables you to visually snooze or dismiss an item. The dialog is completely customizable and localizable and gives you the ability to modify each object’s display text and icon. Built-in reminder dialog Dialog’s display routine raises several events, allowing you to cancel...June 10, 2010
