Q1 2009 SP1 (version 2009.1.413) The latest improvements and additions to both the suites are here and ready for download under the users' accounts. What's New in RadControls for WPF We added three new controls: RadColorPicker Telerik Color Picker control allows the users to choose a color from more than 20 pre-defined palettes. Additionally, custom palettes can also be defined by the users. RadTimePicker Telerik TimePicker control is an easy to use control allowing you to integrate time selection in your web applications. The control exposes an advanced parser that converts numeric values into valid time. Using the templates of the TimePicker control you can...

For all you tweeps out there, this is a quick plug for the newest Twitter client on the block, digiTweet. I was first alerted to this new client on Channel 10, and just started using it with my account. I must say I am very pleased. For a beta product, this one gets two thumbs up! It’s built with WPF and is open source (you can find it on CodePlex). I also happen to like the sleek interface. Being a .NET guy, I’m partial to apps that are build with .NET (the Twitter client I’ve been using, TweetDeck, was built with Adobe...

RadChart supported point mark visual indicators for chart series like Line, Area, Spline, etc. from version one, however, customization of these indicators was hard and certainly not for the faint-hearted. With the latest version of the control released this week (Q1 2009 SP1) we introduced two major improvements that significantly simplify the interaction with the point mark indicators.   Option 1: Customizing the appearance of the point marks through the PointMark API and predefined point mark shapes RadChart supports 8 predefined shapes that you can use for the point marks (members of the Telerik.Windows.Controls.Charting.MarkerShape enumeration): Circle (default) Diamond Hexagon Triangle Square SquareRounded StarFiveRay StarEightRay   Here is a sample code snippet that demonstrates...

Those of you paying attention to “conference news” are probably aware of Microsoft’s entrance in to the cloud computing space via their platform code-named “Windows Azure.”  This version of “Windows in the cloud” essentially makes it possible to easily build and deploy .NET web applications to Microsoft’s hosted cloud infrastructure. The benefits of deploying your application to the cloud are (potentially) many, but I am going to assume you are already aware of the key “selling points” (such as scalability, scalability, and…oh yeah, scalability). TELERIK IS CLOUD READY I’m pleased to report that Telerik is “Cloud Ready.” This is a bit of...

Another popular feature in RadGrid for ASP.NET AJAX is header context menu and I’ve made small demo how to achieve the same in RadGridView for Silverlight:   Similar to the custom filter row you can enable this functionality for your grid with a single property: <telerikGrid:RadGridView x:Name="RadGridView1" telerikGridViewHeaderMenu:GridViewHeaderMenu.IsEnabled="True" telerik:StyleManager.Theme="Vista" /> Enjoy! [Download]...

I recently posted an entry regarding the Radial Gauge for WPF where I demonstrated how you can create a half circle gauge.  Not long after that post, I received a question asking about Linear Gauges and how to use multiple scales in a single Linear Gauge.  It is not that there is a functional difference, but rather a visual difference.  The Office Black theme (shown below) has a border area in the middle where the linear gauges were overlapping causing a visual collision.  There are a number of ways that you can accomplish a task and I think one of...

With all the new features we have introduced in our latest release you might have missed some of the improvements we have implemented in the framework for ASP.NET Online Demos. These are the most important changes that will improve the experience of browsing through the demos: New Search: You can now quickly search the titles of all demos (They are now about 700!)   Change Skin: There is a new option to change skins in the demos. You can easily see how the demos will look if you set another skin. The change skin dropdown is implemented ...

To enable RadContextMenu for every grid data row you should do: 1) Handle RowLoaded event for the grid and create RadContextMenu: void RadGridView1_RowLoaded(object sender, RowLoadedEventArgs e) { if (!(e.Row is GridViewHeaderRow) && !(e.Row is GridViewNewRow)) { RadContextMenu rowContextMenu = new RadContextMenu(); // create menu StyleManager.SetTheme(rowContextMenu, StyleManager.GetTheme(RadGridView1)); // set menu Theme // create menu items rowContextMenu.Items.Add(new RadMenuItem() { Header = "Show row ID property value" }); ...

Say you've assigned a resource to an appointment and you want to make it visually distinctive from the rest.  The resource can be anything - room, status, priority and so on. Until the Q1'09 release this required writing some code, but not any more. You can now define a set of resource filters that will apply a CSS class when a match is found. For example: <telerik:RadScheduler runat="server" ID="RadScheduler1" ...> <ResourceStyles> <telerik:ResourceStyleMapping Type="Calendar" Text="Development" ApplyCssClass="rsCategoryGreen" /> <telerik:ResourceStyleMapping Type="Calendar" Text="Marketing" ApplyCssClass="rsCategoryRed" /> <telerik:ResourceStyleMapping Type="Calendar" Text="Work" ApplyCssClass="rsCategoryOrange" /> </ResourceStyles></telerik:RadScheduler> .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; } You can match resource's type, key and/or text. All matching rules will be applied. For your convenience, we've included a number of predefined styles: rsCategoryBlue...

As you know RadControls for ASP.NET AJAX controls fully leverage .NET 3.5 and come with built-in support for LINQ, LinqToSQL, EntityDataSource, ADO.NET DataServices, and WCF Web Service. With Q1 2009 our online examples feature .NET 3.5 examples for all databound controls (Grid, Scheduler, ComboBox, Menu, TreeView, PanelBar). In this post I will guide you through the process of creating a RadComboBox which loads its items on demand using WCF services. This will be a step by step tutorial, but if you are familiar with the process you can jump directly to the online demo. The steps below show how to load the items of RadComboBox...
