    Building Real Applications with Telerik MVC & OpenAccess – Introduction

    Hi every one, I want to take a moment and introduce you to a series I will be writing here on Telerik blogs.  I will be creating an MVC2 application utilizing Telerik MVC extensions, Open Access, and jQuery.  The goal is to discuss real world problems that are faced when building this type of application, and to show solutions to these issues. It will start with building a model, then the DAL, and then move onto UI issues.  I will also show ways to handle large record sets with OA fetch plans/caching, and show some tips/tricks to help keep the UI...

    Rating column for RadGrid for ASP.NET AJAX

    Here is yet another handy column type coming for RadGrid. The GridRatingColumn will show a RadRating control for every data item in your RadGrid, both in view and edit mode. GridRatingColumn will support 2 modes of interaction. In the standard mode, GridRatingColumn will behave like an ordinary editable column. It will display a read-only RadRating control when the item is in view mode and an editable RadRating control when in edit mode. Alternatively, the rating column will allow you to change the rating value even in view mode. Thus, when RadGrid posts back, you can get the updated value on the server...

    Embedding YouTube video in RadListView for ASP.NET AJAX

    Have you ever thought of embedding a YouTube video in the context of a data-bound control? Recently, a client of ours asked for such a demo and this inspired me to create a code-library project that features this scenario and uses RadListView for ASP.NET AJAX as ‘videos host’. Depending on your goal, you can control the player via JavaScript code or you can just embed a static object. In the latter case you will need something like this: 1: <object width="425" height="344"> 2: <param name="movie" value="http://www.youtube.com/v/QT0e5XqNZdo&hl=en_US&fs=1&rel=0&color1=0x5d1719&color2=0xcd311b"></param> ...

    Visual Style Builder now supports Telerik Extensions for ASP.NET MVC

    The Visual Style Builder for ASP.NET is now compatible with the shiny MVC extensions. The generated CSS code got a bit smaller, too. In order to celebrate this, I give you the lovely PinkPanther skin, for your visual pleasure.

    Calculated column in RadGridView for Silverlight + math expressions

    When the data layer does not allow to perform calculations we often need to harness the UI. Here is a a simple case  - in our business object we have the Price and the Count properties. We will have RadGridView to calculate the Total  for us in a calculated column.   Please download this sample project   If you peek into the sample project you will notice we are using a pretty standard Silverlight approach : We bind the value of the calculated column with a Binding Converter : <telerik:GridViewDataColumn Header="Total" Background="Bisque" DataMemberBinding="{Binding Converter={StaticResource CalculatingConverter}}" TextAlignment="Right" />   The calculation “logic” is in the Convert method of CalculatingConverter.cs   public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) ...
