    Why we have built RadDomainDataSource for Silverlight?

    Although Rossen has stated almost all of the things in his introductory blog post about RadDomainDataSource I wanted to create a separate blog entry which answers the most important question that you might be asking: “Why Telerik have developed their own version of a domain data source component?” Here is the answer: We felt your pain We have received numerous forum posts and support tickets stating that you want a codeless approach to data-binding that supports most common data operations without the need for any custom code. During the times when RadDomainDataSource was not available you will have to write hundreds of lines of code in...

    An MVVM Approach to Telerik Domain Services for Silverlight

    There are only about 7 hours we have left in 2010 and this will be my last blog post for this year. For those of you who are not familiar with the new RadDomainDataSource control for Silverlight, here is my introductory blog post. This one describes how to load data with the new control and this one is about performing CRUD. Having read these three blogs might lead you to the next logical question: What about MVVM support? I truly believe that every time someone places an UI element or a control in his view model, a baby kitten dies somewhere. So what can...

    Creating CRUD application with RadDomainDataSource for Silverlight

    I will extend my colleague’s blog post series regarding RadDomainDataSource control with an example how to create simple CRUD (Create, Read, Update and Delete) application. For more information how to load data initially you can take a look at this blog post. Along with RadDomainDataSource control Telerik provides codeless solution for CRUD operations powered by WCF RIA Services. The solution is a combination between RadGridView and RadDomainDataSource.   First let’s create a default Silverlight project as following:     Next step is to create ADO.NET Entity data model called Northwind.edmx. For the sake of the example I’ll create this entity model with a Northwnd.mdf...

    Loading data with RadDomainDataSource for Silverlight

    will continue the series of blog posts about RadDomainDataSource with the most important one – the one about loading data. If you are not familiar with RadDomainDataSource then you should go back and read my introductory blog post. Let us move straight to the data load lifecycle. Triggering a Load A load operation can be triggered in two ways. You can either call the Load method explicitly or you can rely on the AutoLoad functionality, which I will explain later in this post. Building The Query After a load has been requested a query based on user input is constructed on the client. This query tells the...

    Binding Telerik Grid for ASP.NET MVC to OData

    We have just made a nice demo application showing how to bind Telerik Grid for ASP.NET MVC to OData using Telerik TV as OData producer. The grid supports paging, sorting and filtering using OData’s query options. To do that we implemented a helper JavaScript routine (defined in an external JavaScript file which is included in the sample project) which is used to bind the grid. Here is how the code looks like: @(Html.Telerik().Grid<TelerikTVODataBinding.Models.Video>() .Name("Grid") .Columns(columns => { columns.Bound(v => v.ImageUrl).Sortable(false).Filterable(false).Width(200).HtmlAttributes(new { style="text-align:center" }); ...
