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,...

This post might seem like a no brainer, but I've received quite a few inquiries on this matter recently, so decided to post here.  Let's say you have a parameter of Type: DateTime with AllowNull: true and we filter on a field based on the input parameter value i.e.: Expression        Operator      Value ===========   ========  ================================= =Fields.MyField        =            =Parameters.MyParam When we tick the 'null' checkbox, it basically filters the report to find the Fields with Nulls. However one might expect that it just won't filter at all with this setup. And indeed if you do not wish to filter, you should not have to. Then how do you handle "empty/blank" values in such cases and...

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,...
