Implementing Data Paging with RadDataBoundListBox and the OnDemandManual Data Virtualization Mode
It is clear that a good data driven Windows Phone 7 application must have a smart approach of handling large amounts of data and keeping jagged scrolling and long lasting loading screens away from the end-users. There are a bunch of approaches which handle similar situations but recently I had a discussion with a developer using our controls which focused on implementing data paging as a way of coping with large amounts of data. During this discussion I came up with an idea to utilize the OnDemandManual data virtualization mode of our RadDataBoundListBox to implement a mechanism which loads pages of... -

RadChart for Windows Phone 7 and Data Binding
The fastest chart for windows phone 7 is just around the corner and it is not only fast, it is also very easy to use. To prove how easy to use RadChart is, consider the following steps which take the developer from a blank phone page to a page with a working chart that visualizes real data. In short the steps are these: Create chart object -> Add axes -> add series -> bind series to data. That’s right RadChart will support data binding on day -1 (this is the beta so it is not day 1 yet). Now let’s dig right into it. First...June 06, 2011 3 min read -

Let’s build a board game with RadGridView for WinForms
You probably know RadGridView for WinForms. It became a must for every serious business application for its great and widely used features – load-on-demand hierarchy, self-referencing hierarchy, grouping, sorting, filtering, exporting capabilities and many others. There is one more cool feature that will greatly improve the user experience of your application – our built-in drag and drop mechanism. This is the core feature of the application that we would like to introduce today, namely Telerik Checkers. As the name implies, Telerik Checkers is an implementation of the standard Checkers game and follows most of its rules. The drag and drop restrictions and customizations are possible thanks to the... -

Complex filtering for RadChart
RadChart allows you to programmatically filter its data using FilterDescriptors as demonstrated in our help topic. However there are scenarios where you would like to have more complex filtering. For a sample scenario where a Chart is drawn according to the filtered RadGridView’s data - read further. The Chart and the GridView will be populated with the same data source – List of Business Objects: public class MyDateObject { public double SampleValue { get; set; } public DateTime Date { get; set; } } public class MyDataContext { public const int min = 20; public const int max = 80; public ObservableCollection<MyDateObject> List { get; set; } Random r = new Random(); DateTime baseDate = DateTime.Today; public MyDataContext() { this.CreateChartData(); } private void CreateChartData() { List = new ObservableCollection<MyDateObject>(); for (int i = 0; i < 15; i++) { List.Add(new MyDateObject() { SampleValue = r.Next(min,... -
