    Gracefully degrade RadChart for Silverlight in ASP.NET

    In a recent webinar, I showed an example of how you can build a superior user experience in an ASP.NET website by using RadChart for Silverlight. The Telerik Silverlight chart has animations, rich rendering, and is much more visual appealing than the “static” RadChart for ASP.NET. But while the Silverlight chart is a great way to enhance data visualizations in your ASP.NET site, how do you handle users that don’t have Silverlight installed? One approach is to implement “graceful degradation.” Graceful degradation is an important and familiar principle in web design, and essentially it means this: if you build features into...

    Mouse Right Click, Double Click and Mouse Wheel in RadControls for Silverlight

    Telerik RadControls for Silverlight provide three routed events in addition to the Silverlight mouse events: MouseWheel, MouseDown and MouseUp. The latter two enable the developers to check for DoubleClick and RightClick in their applications. I will briefly show how to use this functionality: 1) MouseWheel: using Telerik.Windows.Input; ... Mouse.AddMouseWheelHandler(element, OnMouseWheel); ... private void OnMouseWheel(object sender, MouseWheelEventArgs args) { var delta = args.Delta; } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   In most cases you just need to make a ScrollViewer to respond on the mouse wheel rotations. We implemented this in the ScrollViewerExtensions.EnableMouseWheel attached behavior, so you don't have to: xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls" <ScrollViewer telerik:ScrollViewerExtensions.EnableMouseWheel="true"> ... </ScrollViewer> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } NOTE: To successfully handle the mouse wheel events, the Silverlight plugin should be in windowless mode.   2) RightClick using Telerik.Windows.Input; ... Mouse.AddMouseUpHandler(element, OnMouseUp); ... private void OnMouseUp(object sender,...

    Saving some lines of code when using RadWindow

    If you are using some of the predefined modal dialogs part of RadWindow: Alert, Prompt and Confirm you may find this article quite handy. As you know the calls to these methods are asynchronous, thus you cannot stop the current UI thread in order to get the user feedback from the windows synchronously. This introduces some issues such as the need to declare class member variables whenever they may not be necessary. Due to that there have been a few requests on our support website to create a generic parameter inside the static calls of the dialogs with the purpose of carrying...

    Integrating RadChart for Silverlight in existing ASP.NET applications

    There’s an emerging trend to integrate cool new silverlight controls into existing production asp.net solutions. And why wouldn’t it be there? There are many  asp.net applications in production out there that have been working quite well and don’t need to be replaced by a completely new technology. Wouldn’t it be nice, however, to spice them up a little with some rich silverlight visualization tools? This is exactly what a lot of our customers have been asking for lately. Well, here you can see some resources we published that will help anyone who wants to plug in RadChart for Silverlight in...
