How to add a right click context menu on a TextBox in Silverlight and also support simple editing commands, like Cut, Copy and Paste? This is pretty easy with RadContextMenu for Silverlight and I will show you now: First I declared a TextBox and set the RadContextMenu.ContextMenu attached property on it: <TextBox x:Name="TextContainer" AcceptsReturn="True" TextWrapping="Wrap" Text="Right click to open a fully functional context menu that depends on the selection and the clipboard content">    <telerikNavigation:RadContextMenu.ContextMenu>        <telerikNavigation:RadContextMenu ItemClick="ContextMenuClick" Opened="ContextMenuOpened" Closed="ContextMenuClosed">             <telerikNavigation:RadMenuItem Header="Cut" />             <telerikNavigation:RadMenuItem Header="Copy" />             <telerikNavigation:RadMenuItem Header="Paste" />         </telerikNavigation:RadContextMenu>     </telerikNavigation:RadContextMenu.ContextMenu> </TextBox> .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; }   If you want to open the context menu with Right click, you need to make the Silverlight plug-in windowless. Otherwise, you should set the EventName and/or ModifierKey properties on RadContextMenu to configure it...

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,...
