Desktop: WinForms

  A common scenario when entering data is a cascade of comboboxes, where the list in the next combo is populated after selecting a value in the previous. A typical example is selecting a country from a combo then selecting from a filtered list of cities in a second combo. We have had tons of questions on how this can be done within a row in RadGridVIew so I decided to make a small demo. I have used a nice List of countries by continent.           There are lots of ways to achieve this with RadGridView. Bellow I have tried to demonstrate...

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...

This was pretty ...

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...

Q3 marks the release of some fantastic new features in the RadControls for WinForms. I know many of you have been waiting for one feature in particular... resource grouping. Well, I'm happy to say, the wait is over, resource grouping is here! Today, I am going to take some time out to explain to you how it works.   Adding Resources Programmatically Creating and adding resources to the RadScheduler is quite simple. In fact, assigning resources to appointments is by no means a new feature of the RadScheduler. The following code creates and adds a resource to the RadScheduler: Resource ...
