    RadGridView for WinForms vNEXT is coming

    The new version of RadGridView is coming in May (as beta) and I am eager to show you some of the new features. There are many methods to indicate errors in RadGridView. However, until now it didn’t support the most natural and easy way for this - the IDataErrorInfo interface. Things have changed, so let me show you how to use this interface.   As MSDN says,“IDataErrorInfo provides the functionality to offer custom error information that a user interface can bind to.” Actually, you don't need to know anything about this interface. You can just set the ErrorText property of the desired row or cell: this.radGridView1.Rows[5].ErrorText = "There...

    Upgrade Existing WinForms Applications to Use the Latest RadControls

    Upgrading projects to new versions can be a pain, especially when you have to update several assemblies from a single version, as is the case with RadControls for WinForms. Q1 2010 simplifies this process a lot, by giving a couple of ways (one new and one updated) to upgrade existing applications to the latest and greatest version of RadControls for WinForms: By using the new Visual Studio Extensions (VSX), available in VS2005, VS2008 and VS2010 RC; By using the updated Project Upgrade Utility. Here are the steps: Upgrading a classic Windows Forms application to the latest RadControls for WinForms by using the Visual Studio Extensions Install...

    WinForms RadGridView vNext will feature new hierarchy modes and performance improvements!

    February 26, 2010 Share
    During the past year, we received many suggestions for new features and bug fixes for RadGridView for WinForms. After analyzing them we realized that we should do a major refactoring of both the data layer and the UI of our grid control. Then we set an ambitious goal -- to refactor the control and implement the most wanted features. This is obviously a massive task and the new grid control will not be part of Q1, but it is coming up afterwards as beta, and will be officially available for Q2 2010. This will give us enough time to test all...

    Sales Dashboard Application for Windows Forms

    Shortly after the Q3 2009 release we developed the Sales Dashboard Application for Windows Forms - a composite business application for visualizing a company’s sales force performance. It is built with the Q3 2009 versions of Telerik’s WinForms components, RadChart for WPF, Telerik OpenAccess ORM, and implements the Telerik CAB Enabling Kit for WinForms, which helps in the development of smart-client line-of-business (LOB) applications. Since the interest in this application is still high, we felt the need to have a dedicated place to discuss this application. In case you have not played with it yet, download the source code, and enjoy!   Also check: Silverlight/WPF Sales...

    Gmail-like labels in RadGridView for WinForms? No problems!

    December 15, 2009 Share
    As you probably know, RadControls for WinForms are built on top of our own Telerik Presentation Framework. This especially designed framework gives you the ability to extend the existing RadControls to a great level. Today, I am going to share with you how you can plug Gmail-like labels in RadGridView for WinForms (http://www.telerik.com/products/winforms/gridview.aspx). First of all we need the construction blocks for the labels. These blocks are represented by a very important element of our framework – the LightVisualElement. Several RadControls use this element extensively – RadTreeView, RadPanelBar, RadCalendar and RadGridView. The advantage of this element is that it incorporates all essential...
