    Integrating Silverlight Data Visualization controls with WCF RIA Services

    Hello everyone! There are several blogposts which demonstrate how to bind RadControls to an SQL database using WCF RIA services. This one will show how the Data Visualization controls can be bound to а sample database with RIA services. For this sample a combination of RadTimeBar and RadLinearSparkline is used without code behind modifications or ViewModel. Changing the selection of TimeBar’s time span updates the “Flight Statistics” and “Arrivals and Departures statistics” charts. The Bar Chart is populated with the number of Arrivals per Date (as being selected) and the Pie shows the Total of the Arrivals/Departures for the chosen...

    Reading/Writing cookies with HtmlPlaceholder for Silverlight

    Recently we received a support ticket with a question whether RadHtmlPlaceholder provides support for cookies. By default, RadHtmlPlaceholder doesn't have a mechanism for reading/writing cookies. However, with the right bits of JavaScript, everything is possible :) Imagine you have an HTML page which you want to read/write cookies to and all this has to happen from Silverlight. First, you need few JavaScript methods for reading/writing cookies. Let's call the page we want to read/write cookies to CookiesPage.html. <html>     <head>         <title>Cookies Page</title>         <script type="text/javascript">             // Create a cookie with the specified name and value             function SetCookie(name, value) {                 document.cookie = name + "=" + value;                 alert("Cookie successfully set");             }             // Retrieve the value of...

    Getting Started Video Series for RadTimeBar for Silverlight and WPF

    A week after the official release of RadTimeBar for Silverlight and WPF with the Q1 2011 SP1 release, we have some fresh new resources ready for you to watch to start getting the hang of working with RadTimeBar and integration with other RadControls. Last week I blogged about the Official Release of RadTimeBar, which included walking through some examples and some sample code.  But some of you would rather see it in action along with an expert voice on how this integration can take place - and we heard you!  We have just published three new videos up to Telerik TV...

    How to create Scatter Error Bars and Box Plot Series with RadChart for SL/WPF

       Currently RadChart provides 27 2D Chart types for SL/WPF. You can easily customise the existing chart types to create a more complex series like the box plot(also known as box-and-whisker diagram and widely spread in descriptive statistics). This blog post will demonstrate how to create Box Plot and Scatter Error bars by reusing the default Styles of the CandleStick and Scatter series and adding custom CandleStick / CandleStickSeriesDefinition (ScatterPoint/ ScatterSeriesDefinition) pair of classes. Box Plot: The BoxPlot have five number summaries: the smallest observation (sample minimum), lower quartile(Q1), median (Q2), upper quartile(Q3), and largest observation (sample maximum).For the purpose the Open, Close, High and Low...

    Official Release of RadTimeBar for Silverlight and WPF

    When we rolled out the Q1 2011 release, there was a surprise control that we included in the release as a Beta version – RadTimeBar.  This control is useful for scenarios where you require a birds-eye view of your time-based data, be it sales history, support volume, or any other statistic that you might want to track over a longer period of time. The real value in the RadTimeBar control, however, is in the integration scenarios that it offers with other controls from RadControls for Silverlight and WPF.  By utilizing data-centric controls like RadGridView and RadChart with the RadTimeBar, your “birds-eye view”...
