Web: ASP.NET MVC

Wow it has been a busy release! I am glad that we managed to release our first home-grown UI extensions for ASP.NET MVC. I hope you like them and please, please share your feedback in the forum.   In this blog post I will highlight the most common problems you may encounter while using the extensions and their solutions. Here we go: The control renders fine but its client-side features do not work The most common reason is that there is no ScriptRegistrar or it is placed before the UI components. It is mandatory that you add a ScriptRegistrar because the UI components require it...

    If you want fast and strongly-typed access to your controller actions, the T4 helpers by David Ebbo are a real treasure. Since we couldn’t provide an support for them out-of the box (after all, the helper classes are generated), here is a small extension method that allows their usage as shown in the screenshot above.   using System.Web.Mvc; using Telerik.Web.Mvc; using Telerik.Web.Mvc.Infrastructure; using Telerik.Web.Mvc.UI; public static class NavigationItemBuilderExtensions { public static NavigationItemBuilder<TItem, TBuilder> Action<TItem, TBuilder> (this NavigationItemBuilder<TItem, TBuilder> instance, ActionResult action) where TItem : NavigationItem<TItem> where TBuilder : NavigationItemBuilder<TItem , TBuilder>, IHideObjectMembers { ...

As you probably know some of our controls support web service load on demand (a.k.a. client-side databinding). Also in ASP.NET MVC we can call controller actions via Ajax. In this blog post I will show you how to populate RadComboBox and RadTreeView on demand by using a controller action which returns JsonResult. Let's start with RadComboBox: Configure RadComboBox for Load on Demand I have added the RadComboBox control to the default Index.aspx view and configured it like this: <telerik:RadComboBox runat="server" ID="RadComboBox1" EnableLoadOnDemand="true" ShowMoreResultsBox="true" EmptyMessage="Type here ..." Height="200px"> <WebServiceSettings Path="Home" Method="LoadItems" /></telerik: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; } The important thing here is that RadComboBox is configured as if it were using a web service...

We have updated our MVC Forum sample application to use the official ASP.NET MVC 1.0, RadControls for ASP.NET Ajax Q1 2009 and the latest installment of Telerik OpenAccess ORM. Online demo | Download...

We have just uploaded a contribution to Microsoft’s MVC design contest – a web-design template free for all to use with the MVC framework. Our entry is a clean, simple, blue-themed web-design generic enough to fit a broad range of scenarios. Please feel free to download and jumpstart your next project. We thought the contest was a great way to further support our clients in their switch to the MVC. Our RadControls for ASP.NET AJAX already boasts full support for the MVC (see live demo, join our forums), so we thought providing an out-of-the-box design solution is a logical next step. Initiatives like this...
