This is Memorial Day weekend in the United States and today represents my last day as a Developer Evangelist for Telerik.  When I joined Telerik, I knew the company mostly from their outstanding reputation as a community supporting organization.  Since joining the company I have seen another side of Telerik that I think people may overlook.  The company slogan is “deliver more than expected” and sure, plenty of companies talk the talk, but very rarely do you see a company put it in action.  I am talking about people who have a real passion to deliver a product that exceeds...

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...

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,...

I recently showed you how to get started working with the RadControls for ASP.NET AJAX on Azure. It’s really a lot easier than you might think. If you missed the first two posts (and the follow-up videos), here they are for quick reference: RadControls for ASP.NET AJAX on Azure Deploying RadControls to Azure Azure Videos on Telerik TV Today, I updated the live running Telerik demo on Azure to feature the complete Telerik Web Mail demo! That means you can now see almost all of the RadControls for ASP.NET AJAX running live on the Azure Cloud. Included in the demo are RadGrid, RadEditor, RadSplitter, RadMenu, RadAjax,...

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...
