Applying Themes on RadControls for Silverlight
The theme engine of RadControls for Silverlight is quite powerful and provides the developers with the ability to apply application-wide theme on all RadControls, as well as specific theme on a single control. If the theme does not contain the needed styles, the controls fallback to their default styles, so you could create an application theme for just a couple of controls and the rest will display with their default styles. We also provide styles for the standard controls, such as Button, CheckBox, RadioButton, etc. which enables you to create application with consistent look and feel. Each theme is distributed as...May 27, 2021 5 min read -

GridView in ComboBox with RadControls for Silverlight
Recently we received several requests for an example, demonstrating how to put a virtualized GridView in a ComboBox popup. The best way to do this in my opinion is to replace the ItemsPresenter of the ComboBox with a GridView. There is some plumbing that has to be done, but I managed to separate it in two attached behaviors. The original idea is described in my blog post for TreeView in ComboBox which I recently updated with the latest control template of RadComboBox for Silverlight. The principle is exactly the same with RadGridView and it should work with very minor adjustments with...May 27, 2021 3 min read -

I’ve made small demo application on how to search Twitter using Twitter REST API and RadGridView for Silverlight: To download Twitter ATOM response you can use simple WebClient: if (!String.IsNullOrEmpty(TextBox1.Text)) { WebClient client = new WebClient(); client.DownloadStringCompleted += newDownloadStringCompletedEventHandler(client_DownloadStringCompleted); if(!client.IsBusy) client.DownloadStringAsync(new Uri(String.Format(urlFormat, TextBox1.Text, pageSize, currentPageIndex))); } and you can parse the response using XDocument.Parse() method: XNamespace atomNamespace = "http://www.w3.org/2005/Atom"; RadGridView1.ItemsSource = from item in... -

Quick Overview of RadCarousel For WinForms
I put together a quick introduction to the RadCarousel for WinForms control and how you can get started working with it. I have shown this control to a number of people during conferences and they always think it is a WPF control instead of WinForms. It is really easy to get things going and simple to work with. I hope you will take a look at the...May 27, 2021 1 min read -

Picking and Choosing Columns with RadGridView for WinForms
Have you ever run into a situation where you needed to allow a user to select which columns they want to see in a grid? If you are using the RadGridView for WinForms you don’t have to lift a finger to implement this functionality. The Column Chooser is available for the RadGridView out of the box. Simply bind your data and you are ready to go. You can access the Column Chooser by right clicking on any column and selecting Column Chooser from the context menu. The Column Chooser is displayed as a floating window next to the application. You can now drag...May 27, 2021 2 min read -

Setting custom skin for the web report viewer
I've been asked a few times by clients how to customize the web report viewer's skins, so they can better match their company identity. I would try to describe 'the process' in this post. We are trying to stay close to the approach used for the RadControls for ASP.NET AJAX, so one who has used our web controls would be pleasantly surprised to find two familiar properties in Telerik Reporting - Skin and SkinsPath. As their names suggest, the first one is used to specify the name of the skin, while the second one specifies the path where this skin can be found. Let's start with... -

Silverlight DragDrop Hello (Real) World Application
A Most Interesting Hello (Real) World Application Sometimes you can get away with a small application to show off some features. But dragging rectangles around is just not enough. You need a TreeView, you need a GridView, ListBox and a good user feedback. Why not place everything in a Docking Control? Some examples of DragDrop can be a bit unrealistic. You do not always have your elements defined in XAML. You cannot always have a reference to the containers you want to drag/drop. So we need to go a bit more real-world. What I tried to do is create a simple application that... -

Computing Values in the RadGridView for WinForms
When working with data there are a number of occasions where you may want to calculate a value for display within a grid. Did you know you can do this within the RadGridView itself? It is really quite simple. To compute a column within the RadGridView you need to set the Expression property of the destination column. This may be a new column that you are adding to the grid to store the value or you can override the value of an existing column by setting the Expression property. Below is an example of the syntax to calculate an average across all...
