Here are the main highlights: Map Sources support – RadMap for Silverlight allows you to visualize rich geographical information from external geo imagery sources. VEMapProvider (Bing Maps)   EmptyProvider – the Map control also supports empty provider that is not connected to any real imagery service;...

    Fairfield / Westchester Code Camp 2009

    November 11, 2009 Share
    So this is not my normal type of post, but I wanted to take a moment to thank the folks over at the Fairfield / Westchester Code Camp for a great time this past Saturday.  They had 24 sessions going over 4 tracks to cover the day, with a lot of great content on everything from my personal favorite, Silverlight, to Azure, F#, Poweshell, and a ton more.  Looking forward to all of the presentations being posted online so I could see some of what I missed.     Telerik was one of the sponsors for this awesome code camp, but aside from...

    Data-binding Telerik CoverFlow for Silverlight + some Routed Commands goodness

    November 05, 2009 Share
    With our still hot Q3 2009 release we introduced a brand new RadCoverFlow control, that was rewritten from scratch in order to be able to exploit some new features in Silverlight 3 that improved both its performance and appearance. We are now using matrix projections to transform the items’ content and pixel shader effects to render the reflection. This allows us to show and properly transform any element in RadCoverFlow, including UI Elements, controls and video, as well as instantly synchronize the reflection. This major change in the control caused major changes in its API and usage patterns. We provide some...

    Virtualized Telerik ComboBox for Silverlight

    October 28, 2009 Share
    In some scenarios it is required to load thousands of items in a ComboBox. Since by default the control creates RadComboBoxItem containers for each data item, it might take some time to open the drop-down. To resolve the problem you only need to change the RadComboBox ItemsPanel with VirtualizingStackPanel: <telerikInput:RadComboBox> <telerikInput:RadComboBox.ItemsPanel> <ItemsPanelTemplate> <VirtualizingStackPanel /> </ItemsPanelTemplate> </telerikInput:RadComboBox.ItemsPanel> </telerikInput:RadComboBox> .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; }   thus making the drop-down to open instantly. Attached is a simple application that loads 1000 items in two RadComboBox controls, one virtualized, the other – not virtualized. The difference between the two controls is visible and becomes much larger if you create 100,000 items! VirtualizingComboBox I hope this helps....
